Summary: | The invention discloses a method for improving coal-slime-whole-burning circulating fluidized bed boiler efficiency. The original outlet size of a hearth is reduced with a reduction ratio of 1:(0.80 to 0.91). An original boiler is transformed to solve the above problems in coal-slime-whole-burning of the circulating fluidized bed boiler, when the load carrying capability is increased to rated load and full load, the bed temperature is restored to be normal temperature, and a returning amount is also obviously increased. The returning temperature is 970 to 980 DEG C, particularly the concentration of nitric oxides in discharged smoke is lowered to about 100mg/m , and the smoke denitrification cost is reduced. The usage amount of ammonium hydroxide is greatly reduced, and more cost is reduced each year. |
