  • Scaling in boilers - Lenntech

    Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the Learn More

Economite burners do well up to 300,000. Riello gas burners are very set up sensitive and need real experience with gas burner set up. When you get above 400,000 BTU's you need to be careful with the gas burner choices. Some burners and boilers …Learn More

  • Boiler Fuel - an overview | ScienceDirect Topics

    The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding device (speed Learn More
