  • Conversion of Coal-Fired Electric Generating to Natural

    improves boiler cleanliness and tends to increase heat absorption. However, combustion- zone radiation rates to the furnace walls tend to be lower. Achieving design steam temperatures and full boiler output can be difficult for a boiler originally designed to burn coal. Higher tube-metal temperatures may be experienced when firing natural gas.Learn More

  • Boiler design for ultra-supercritical coal power plants

    Jan 01, 2013 · Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).Learn More

  • How Do I Connect a Coal Boiler to an Oil Boiler? | Coal

    Apr 11, 2009 · I ran two loops of it. I insulated it myself. Much cheaper and it seems to work OK. I cannot measure a temp loss from coal boiler to oil boiler. I covered each pipe with that 1/2'" thick black insulation, then bundled the four together and wrapped with that foil bubble wrap. They went inside 6" …Learn More

  • Boiler-Venting Considerations - Heating Help

    I switched it back to the manual/always-open state. I intend to replace the electric damper, after reading many posts on The Wall that indicate that a vent damper on an over-sized, not-too-efficient gas boiler paired with a chimney designed for a coal-fired boiler will improve efficiency by keeping the boiler warmer during off-time.Learn More

  • Boiler — The Rhodes Mansion

    The new heating system was designed so that in appearance it would resemble a 1930's boiler, while providing modern comfort and efficiency. The home originally had a large coal-fired, gravity boiler. This was replaced in the 1930's with a "modern" oil-fired boiler.Learn More

  • How they piped coal-fired steam systems - Heating Help #1

    Nov 21, 2014 · "Right. The oil boiler cycles on and off. The coal boiler didn't. It wasn't long before the oil men figured this out. They realized they couldn't pipe their new, oil-fired jobs with those long girdling mains. They began to do things in a different way. Instead of one long main, they ran several shorter mains off the steam boiler's header.Learn More

  • 5 Common Questions About Concealing Surface Pipework

    were in the late 1940s, when there was still a demand for cheap coal-fired boilers. Note that not all round boilers were that bad- I've seen some ads for round tubular boilers that looked like they had plenty of heat-transfer surface. But the usual round cast-iron boiler used a lot more fuel than it should have, even on coal.Learn More

  • Challenges when Converting Coal-Fired Boilers to Natural Gas

    Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls.
