1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

Jul 05, 2009 · Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

Power Generation - Coal Fired

efficiency is the "heat loss" method. Most Eastern Bituminous coal fired utility boilers are capable of around efficiency. It should be pointed out that 90% boiler efficiency can be maintained — yet unit heat rate penalties experienced at that given time may represent more than — or about 200 BTU/KwHr.

Conversion of Existing Coal-Fired Boilers to Natural Gas

improves boiler cleanliness and tends to increase heat absorption. However, combustion -zone radiation rates to the furnace walls tend to be lower. Achieving design steam temperatures and full boiler output can be difficult for a boiler originally designed to burn coal. Higher tube -metal temperatures may be experienced when firing natural gas.
