The role of pulverized coal drying temperature in fly ash

Down-fired combustion, is one of the three boiler combustion modes in the coal-fired power plants. Down-fired boiler widely used in China is a suitable furnace type for combusting the hard-to-burn coal owing to its large lower furnace space, high furnace temperature, long-flame characteristic, etc,, .

Off-design performance analysis of a new 300 MW

Feb 01, 2021 · Generally, when the difference between the softening temperature (ST) and the deforming temperature (DT) of the coal is less than 100 °C, the furnace outlet flue gas temperature θ 1 ″ should be equal or less than the value of ST minus 100 °C .In this paper, the coal DT is 1220 °C and ST is 1300 °C, so the flue gas temperature at the furnace outlet should not be more than 1200 °C.
