How to Run a Coal Fired Boiler at the Best Efficiency …

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.

Boiler Efficiency – an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

2. Boilers Bureau of Energy Efficiency 31 The coal-feed hopper runs along the entire coal-feed end of the furnace. Acoal grate is used to control the rate at which coal is fed into the furnace, and to control the thickness of the coal bed and speed of the grate. Coal must be uniform in size, as large lumps will not burn out com-

Conversion of Existing Coal-Fired Boilers to Natural Gas …

Estimated Boiler Performance and Expected Plant Performance. Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water. Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency.
