The coal used has a heating value (energy released when the fuel is burned) of 29,300kJ/kg. Assuming that 75 percent of this energy is transferred to the steam in the boiler and that the electric generator has an efficiency of 96 percent, determine: the overall plant efficiency (the ratio of net electric power output to the energy input as fuel)

Guideline for Technical Regulation Volume 2

May 06, 2020 · Boiler pricing can vary by the size, style, brand, and efficiency. Most boilers in today's market are high efficiency, which is considered above 87% AFUE for oil-fired boilers, and 90% AFUE for gas-fired boilers. Boiler also have minimum efficiency ratings. Gas-fired boilers must be above 82% and oil fired boilers above 84%.
