Originally posted by edblysard UP had the first steam turbine from GE, it used a recovery system to recycle the steam, condense it back to water, and use it again, saving on water stops.

Double ended with cabs on both ends, 4500 hp, built nov 1948 returned to GE and dismantled. This is the demo unit, ran on UP as #50, on NKP and Pennsy as GE#101. Used bunker C fuel oil, as did the rest of UPs turbines, except Nos 80A/80B, which used pulverized coal in a slurry as fuel. UP is the only buyer. That's great Ed! a lot of info. You mentioned coal in a slurry. To me a slurry is something dry (coal) mixed with something wet (water, oil, gas) Is that what you mean. If it is, what was it mixed with? I need a view of # 80A & B.

That could be true, but in the fifties, I think it was GM, built a bus with a turbine located in the back in a normal position. Most helicopters use turbines now. Maybe they are a diffrent type.

The trubines are started on diesel fuel, and when they reach some ungodly rpm, the coal powder, or bunker c oil, is introduced. By the way, the bunker c or number 2 fuel oil, was so thick, it was preheated by a on board steam heater, so it would flow freely. The compression from the intake blades makes the fuel, no mater what type, into a gas thats quite combustible, and helps ignite the mix. Just like with a diesel, if you compress a fuel fast and dense enough, it will ignite from the friction and heat cause by the compression. Pentrax has the only footage I know of showing the coal turbine, it quite a good looking locomotive, for what it is, but then all the turbines are eye catchers. The gas turbines were regulars at UP's LA east yard,it was one of their turn around points. I think the title of the video is UP's Mighty Turbines. I will dig it out tomorrow, and see if there is a stock number on it. Funny, all this talk about turbines not being used today, due to not being efficent, but no one mentioned Amtrak's turboliners, just put back into service. A jets is a jet is a jet? I will let you know here tomorrow. And to clear up what will sure to be a debate, yes, dry products can be a slurry. Kaloin clay, used to coat printer paper, and make fine china plates, is shipped as a dry slurry in tank cars because it is so fine, it flows like a liquid. Compressed dry, then fired, it can be made into dinner ware, and fine plates. It is pressed dry on to a base paper to make the top quality printer paper you use every day. Thats what the silky or smooth, almost dusty feel is on you printer paper, it kaloin dust.

Stay Frosty, ] Hi There Ed, In many modern electric power plants coal is pulverised like you described. I have a friend who is an operator in the Muscateen Iowa power plant. He told me that the coal is forcefully injected from the four corners of the firebox into the air where it forms a plasma ball that is so bright that you need tinted glass like a welders helmet in order to view it. The ball just hangs there in mid-air. They burn two high capacity hopper cars of coal and hour. Just the same, as good a fuel as it is, coal blown into a turbine would be so abrasive I just don't see how they would have even tried that experiment. In navel ships that use bunker oil the oil is pumped into the tanks hot where it cools and solidifies to a tar consistancy. When it is needed it is heated with a steam line that makes the oil flow again. Say! this isn't really related but, In MN. the state has mandated that all diesel fuel be mixed with soybean oil. A friend of mine owns a fuel distribution buisness here. He said that soybean oil solidifies at a higher temp. then diesel fuel. In a cold climate like MN. there are going to be problems. He said that the soybeen oil is going to have to be heated. Have you run into soy oil for fuel yet?

And the coal "dust" or slurry is introduced into a combustion chamber first, where the air from the compression blades will compress and ignite it, the exhaust gas produced is what turns the turbine. This was a gas turbine also, just the fact that the fuel was pulverized coal set it apart. The same principle is used in the "Gas" turbines, its the exhaust gas from the combustion chamber that flows over and turns the turbine. These were the same basic design as the jet turbine engines GE made, and still makes, a set of intake or compression blades, followed by a combustion chamber, with a set of turbine baldes in the exhaust side, with the turbine connected to a standard alternator/generator set up via a drive shaft. The compressor blades ran off the other end of the same shaft through reduction gears, so the faster or hotter the exhaust gas flowed, the faster the compression baldes worked, but the gears keep it within a certain range, you could blow out the combustion process if you let the compression side get too intense, or start a fire if you allowed them to turn too slow because the fuel wouldnt compress enought to become a gas. The exhaust didnt provide any push whatsoever, it just drove the turbine. But it is the same exhaust gas that also corroded the turbine blades, both the bunker c and the coal slurry exhaust gas produced was very corrosive, and with the coal slurry, some small particulate matter would also escape the combustion process, and further degrade the turbine blades. The standard gas turbines had a aux diesel in the A unit, with a small generator, that provided power to the traction motors when the locomotive was moving about the yards for service, it cost to much, and was to loud to use the turbine to do that. With a steam turbine, you dont have to worry about compression or combustion, the steam is hot enought to turn the turbine, more steam, more rpm on the turbine. Personaly, I feel that with the advances in metals and composite compounds, along with computer logic chips, like the "computer" in your new car, the gas turbine could be a realistic contender for coast to coast freight and passenger trains. The fuels are here now. Shoot, you could run one on LPG, butanes or propane, even methanol or compressed natural gas.

For the speeds that UPS and Fed EX are asking for, Gas Turbine's are the only economical choice. Let us not forget the advantages of Gas Turbine. Once at speed they can be very therfty on fuel.

He told me that the coal is forcefully injected from the four corners of the firebox into the air where it forms a plasma ball that is so bright that you need tinted glass like a welders helmet in order to view it. The ball just hangs there in mid-air. They burn two high capacity hopper cars of coal and hour. Just the same, as good a fuel as it is, coal blown into a turbine would be so abrasive I just don't see how they would have even tried that experiment. In navel ships that use bunker oil the oil is pumped into the tanks hot where it cools and solidifies to a tar consistancy. When it is needed it is heated with a steam line that makes the oil flow again. Say! this isn't really related but, In MN. the state has mandated that all diesel fuel be mixed with soybean oil. A friend of mine owns a fuel distribution buisness here. He said that soybean oil solidifies at a higher temp. then diesel fuel. In a cold climate like MN. there are going to be problems. He said that the soybeen oil is going to have to be heated. Have you run into soy oil for fuel yet?

And the coal "dust" or slurry is introduced into a combustion chamber first, where the air from the compression blades will compress and ignite it, the exhaust gas produced is what turns the turbine. This was a gas turbine also, just the fact that the fuel was pulverized coal set it apart. The same principle is used in the "Gas" turbines, its the exhaust gas from the combustion chamber that flows over and turns the turbine. These were the same basic design as the jet turbine engines GE made, and still makes, a set of intake or compression blades, followed by a combustion chamber, with a set of turbine baldes in the exhaust side, with the turbine connected to a standard alternator/generator set up via a drive shaft. The compressor blades ran off the other end of the same shaft through reduction gears, so the faster or hotter the exhaust gas flowed, the faster the compression baldes worked, but the gears keep it within a certain range, you could blow out the combustion process if you let the compression side get too intense, or start a fire if you allowed them to turn too slow because the fuel wouldnt compress enought to become a gas. The exhaust didnt provide any push whatsoever, it just drove the turbine. But it is the same exhaust gas that also corroded the turbine blades, both the bunker c and the coal slurry exhaust gas produced was very corrosive, and with the coal slurry, some small particulate matter would also escape the combustion process, and further degrade the turbine blades. The standard gas turbines had a aux diesel in the A unit, with a small generator, that provided power to the traction motors when the locomotive was moving about the yards for service, it cost to much, and was to loud to use the turbine to do that. With a steam turbine, you dont have to worry about compression or combustion, the steam is hot enought to turn the turbine, more steam, more rpm on the turbine. Personaly, I feel that with the advances in metals and composite compounds, along with computer logic chips, like the "computer" in your new car, the gas turbine could be a realistic contender for coast to coast freight and passenger trains. The fuels are here now. Shoot, you could run one on LPG, butanes or propane, even methanol or compressed natural gas.

QUOTE: Originally posted by kevarc Like I said before, no you couldn't, the size of the turbine and all the aux equipment would limit it to one turbine per frame. Just becasue the engine is small does not mean that it would be adaptable to what would be required. There are a great many limits other than size.
QUOTE: Originally posted by sooblue Originally posted by edblysard UP had the first steam turbine from GE, it used a recovery system to recycle the steam, condense it back to water, and use it again, saving on water stops.

Condenser system too complicated, heavy maintainance on boiler, considered a failure, returned to GE 1939. First Gas Turbine GE demo unit#101, numbered UP 50 when tested by UP. Double ended with cabs on both ends, 4500 hp, built nov 1948 returned to GE and dismantled. This is the demo unit, ran on UP as #50, on NKP and Pennsy as GE#101. Used bunker C fuel oil, as did the rest of UPs turbines, except Nos 80A/80B, which used pulverized coal in a slurry as fuel. UP is the only buyer. That's great Ed! a lot of info. You mentioned coal in a slurry. To me a slurry is something dry (coal) mixed with something wet (water, oil, gas) Is that what you mean. If it is, what was it mixed with? I need a view of # 80A & B. I must know more [:p] Thanks, Sooblue 23 17 46 11 Reply edblysard Member sinceMarch 2002 9,265 posts Posted by edblysard on Friday, July 25, 2003 12:42 AM Hi sooblue, The slurry was pulverized coal, almost as fine as talc, it will burn quite hot. The trubines are started on diesel fuel, and when they reach some ungodly rpm, the coal powder, or bunker c oil, is introduced. By the way, the bunker c or number 2 fuel oil, was so thick, it was preheated by a on board steam heater, so it would flow freely. The compression from the intake blades makes the fuel, no mater what type, into a gas thats quite combustible, and helps ignite the mix. Just like with a diesel, if you compress a fuel fast and dense enough, it will ignite from the friction and heat cause by the compression. Pentrax has the only footage I know of showing the coal turbine, it quite a good looking locomotive, for what it is, but then all the turbines are eye catchers. The gas turbines were regulars at UP's LA east yard,it was one of their turn around points. I think the title of the video is UP's Mighty Turbines. I will dig it out tomorrow, and see if there is a stock number on it. Funny, all this talk about turbines not being used today, due to not being efficent, but no one mentioned Amtrak's turboliners, just put back into service. A jets is a jet is a jet? I will let you know here tomorrow. And to clear up what will sure to be a debate, yes, dry products can be a slurry. Kaloin clay, used to coat printer paper, and make fine china plates, is shipped as a dry slurry in tank cars because it is so fine, it flows like a liquid. Compressed dry, then fired, it can be made into dinner ware, and fine plates. It is pressed dry on to a base paper to make the top quality printer paper you use every day. Thats what the silky or smooth, almost dusty feel is on you printer paper, it kaloin dust.

This was a gas turbine also, just the fact that the fuel was pulverized coal set it apart. The same principle is used in the "Gas" turbines, its the exhaust gas from the combustion chamber that flows over and turns the turbine. These were the same basic design as the jet turbine engines GE made, and still makes, a set of intake or compression blades, followed by a combustion chamber, with a set of turbine baldes in the exhaust side, with the turbine connected to a standard alternator/generator set up via a drive shaft. The compressor blades ran off the other end of the same shaft through reduction gears, so the faster or hotter the exhaust gas flowed, the faster the compression baldes worked, but the gears keep it within a certain range, you could blow out the combustion process if you let the compression side get too intense, or start a fire if you allowed them to turn too slow because the fuel wouldnt compress enought to become a gas. The exhaust didnt provide any push whatsoever, it just drove the turbine. But it is the same exhaust gas that also corroded the turbine blades, both the bunker c and the coal slurry exhaust gas produced was very corrosive, and with the coal slurry, some small particulate matter would also escape the combustion process, and further degrade the turbine blades. The standard gas turbines had a aux diesel in the A unit, with a small generator, that provided power to the traction motors when the locomotive was moving about the yards for service, it cost to much, and was to loud to use the turbine to do that. With a steam turbine, you dont have to worry about compression or combustion, the steam is hot enought to turn the turbine, more steam, more rpm on the turbine. Personaly, I feel that with the advances in metals and composite compounds, along with computer logic chips, like the "computer" in your new car, the gas turbine could be a realistic contender for coast to coast freight and passenger trains. The fuels are here now. Shoot, you could run one on LPG, butanes or propane, even methanol or compressed natural gas.

WHY, I did a little reading on them. They are a perfect fit for High Speed Intermodel service between California and Chicago. For the speeds that UPS and Fed EX are asking for, Gas Turbine's are the only economical choice. Let us not forget the advantages of Gas Turbine. Once at speed they can be very therfty on fuel.

Originally posted by edblysard Hi sooblue, The slurry was pulverized coal, almost as fine as talc, it will burn quite hot. The trubines are started on diesel fuel, and when they reach some ungodly rpm, the coal powder, or bunker c oil, is introduced. By the way, the bunker c or number 2 fuel oil, was so thick, it was preheated by a on board steam heater, so it would flow freely. Stay Frosty, ] Hi There Ed, In many modern electric power plants coal is pulverised like you described. I have a friend who is an operator in the Muscateen Iowa power plant. He told me that the coal is forcefully injected from the four corners of the firebox into the air where it forms a plasma ball that is so bright that you need tinted glass like a welders helmet in order to view it. The ball just hangs there in mid-air. They burn two high capacity hopper cars of coal and hour. Just the same, as good a fuel as it is, coal blown into a turbine would be so abrasive I just don't see how they would have even tried that experiment. In navel ships that use bunker oil the oil is pumped into the tanks hot where it cools and solidifies to a tar consistancy. When it is needed it is heated with a steam line that makes the oil flow again. Say! this isn't really related but, In MN. the state has mandated that all diesel fuel be mixed with soybean oil. A friend of mine owns a fuel distribution buisness here. He said that soybean oil solidifies at a higher temp. then diesel fuel. In a cold climate like MN. there are going to be problems. He said that the soybeen oil is going to have to be heated. Have you run into soy oil for fuel yet?
