  • oil fired boiler not working - help! | Mumsnet

    Feb 14, 2007 · We've got a coal fired back boiler so ned to keep the coal fire in the lounge stoked up in order to heat the house. Complete pain in the bottom when the coal froze and I needed to hack it out of the coal bunker before it could even make it onto the fire. Grrrrrr. Eventually (when we find a plumber who'll return our calls) Learn More


    from a No. 2 Oil to a No.6 or high asphaltene Bunker C grade oil or road grade asphalt or Petroleum Coke. In such cases, variation in viscosity (burning something like "Black Strap Molasses" or hot maple syrup for the liquids – coke is a solid more like coal) can have a serious impact on combustion efficiency and overall boiler efficiency.Learn More

  • Blending Coal in Thermal Power Stations

    Mar 05, 2005 · We use Coalogic to track all the coals in the yard to deliver the "target spec" coal to the boiler in real-time. This also includes modeling of the flow of the bunkers so that the blend is actually what should go to the boiler and not just to the bunkers.Learn More

  • Coal Fired Power Stations | Hawk Measurement Systems

    Boiler Coal Bunker: The boiler bunker was 20 meters (65 ft) high. The level transmitter was to control the shuttle conveyer. For application 1 and 2 we provided low frequency 10 kHz loop powered transmitters to overcome dust, rat holing etc. Coal on Belt Detector: Monitoring coal on the conveyor belt. Range 1 …Learn More

  • AccuTrack - Coal quality tracking system - Engineering

    Monitor Coal Quality Online coal analyzers are used to measure and analyze the coal quality variables which are tracked though the bunker coal flow model.

  • Coal Quality Management Model For Dome Storage (DS-CQMM)

    (2001) state that boiler efficiency at power plants is affected mainly by the changes in coal quality. Therefore, coal quality management is a fundamental concern. In order to deliver a uniform product, mines usually use coal blending in order to homogenize mixtures of coal in such a way that the properties of the final blend satisfy particular Learn More

  • Coaling (ships) - Wikipedia

    Coal cannot be pumped and, once loaded, it had to be continuously moved to ensure bunkers nearest the boilers were always full should full power be suddenly needed. These problems were sufficiently serious for the Royal Navy to build HMS Queen Elizabeth as an oil-fired ship despite an abundance of coal and a shortage of oil in the United Kingdom .Learn More
