Methods of Firing Steam Boiler | Electrical4U

Dec 30, 2018 · As the combustion is most efficient pulverized coal firing increases the overall efficiency of a steam boiler. As handling of lighter coal dust is much easier than the handling of heavier coal chips, it is quite easy to control the output of the boiler by controlling the supply of fuel to the furnace.

Comparison of Chars Obtained under Oxy-Fuel and ...

The combustion of coal in conventional power plants produces large amounts of CO2 which contributes to the greenhouse effect. One of the ways to approach the CO2 emissions abatement is to burn the coal in an O2/CO2 atmosphere which eliminates the need of a separation step. In this study, two coals of different rank (a high volatile and a low volatile bituminous) have been burned in a drop tube ...
