The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary

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. There are a few minor losses in boiler which can also

Chromium speciation is vital for the toxicity of products resulting from co-combustion of coal and biomass. Therefore, understanding of formation processes has been studied using a combination of X-ray absorption fine structure (XAFS) spectroscopy and thermodynamic equilibrium calculations. The influence of cofiring on Cr speciation is very dependent on the type of fuel. Cr(VI) contents in the
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.
The aim of this study was therefore to identify the changes in physical and chemical parameters of bituminous coal and slags during the combustion process in different zones of a boiler grate, and in particular the changes in mercury content, as well as the temperature effect on these changes.

Net reductions in boiler efficiency while burning natural gas compared with coal range from approximately 3 percent to 5 percent depending on various factors related to the original furnace design.
Buderus Coal Boiler I don't know if it's still available , but I installed a Buderus Logana multi-fuel boiler in my home back in 1983. It's still going strong. A 5 section cast iron unit with double doors in front and a Sampson (mechanical aquastat) valve for draft control. I burn oil for DHW during the summer and anthracite coal during the winter.
The oxygenated feed-water treatment technology of supercritical unit can effectively decrease the corrosion of water-steam system, and thus steam-water quality and operating efficiency are greatly promoted.
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-
Cofiring biomass and coal is a time-tested fuel-switching strategy that is particularly well suited to a stoker boiler, the type most often found at coal-fired federal facili-ties. However, cofiring has been successfully demonstrated and practiced in all types of coal boilers, including pulverized-coal boilers, cyclones, stokers, and fluidized
