  • Coal Gasification - an overview | ScienceDirect Topics

    Gasification offers potential environmental and efficiency advantages over conventional coal combustion. Efficiency benefits derive from the potential combustion of the gasified coal, commonly referred to as producer gas, in a gas turbine. A Brayton cycle for a gas turbine is a more efficient heat engine than the Rankine cycle used in a boiler.Get Price

  • INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

    Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent.Get Price
