| Abstract: | Based on the reason why the flue gas temperature deviation is occurred in a corner firing boiler and the practical boiler operating parameters, the measure to reduce the deviation by shifting down the position of tertiary air is proposed. For the 300MW pf boiler of Hanchuan Power Plant, thermal calculation results show that there would not be any adverse effect of the air shifting on the combustion stability and slag bond in the furnace. |
