Understanding Coal Power Plant Heat Rate and Efficiency

Sep 16, 2018 · The effective generation of Steam is possible if the efficiency of the boiler using pulverised fuel fired system is high. Efficiency is ratio of output (i.e., steam) to the input. There are two ways of knowing thermal efficiency. One is the direct method and the other one is indirect method efficiency from direct method is calculated as under.

performance of pulverized coal plants. For example; a large utility boiler can be tested and found to be meeting the original design boiler efficiency by completing an ASME boiler heat loss method performance test. Yet the unit heat rate may be off design by over 300 Btu's per kWh due to the non optimization of

Jul 05, 2009 · Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses. Table 3.2.
