  • Effects of low sulfur fuel oils on combustion performance

    Jan 13, 2010 · Irrespective of whether fuel oil is used for load carrying or as support for fuel in a boiler, it is very important to maintain the fuel oil temperature as the amount of unburned fuel collection over a period of time can explode the boiler or lead to air pre-heater fires. Both of this lead to a long outage of the boiler and a loss of production.Learn More

  • The Role of Coal Characteristics in Boiler Operation

    for normal volatile content variations between 25% and 50%, there is little effect on boiler operation or furnace design. The extremely low volatile fuels can give us problems. See Figure 4 for pulverizer capacity reduction when extra fineness is required. In short, pulverized anthracite cannot be fired in a furnace designed for bituminous coal.Learn More

  • Optimizing Boiler-System Efficiency | HPAC Engineering

    Oct 01, 2009 · A commercial facility was operating three 40,000-pph dual-fuel (natural gas and methane) boilers at 5- to 6-percent excess O 2 while experiencing high exit-gas temperatures. The problem was caused by overly conservative combustion characterization during times of low natural-gas costs.Learn More
