Embodiment
[0017] Embodiment: The engineering coal is low calorific value lignite, which has high water content, low calorific value and medium sulfur content. Its main characteristics are easy to catch fire, easy to coke, difficult to burn out, weak abrasiveness, and high content of calcium oxide in the ash (GaO=47.75%).
[0018] The combustion method of the circulating fluidized bed boiler is low-temperature fluidized combustion, which can not only desulfurize but also denitrate, and can also inhibit the formation of CO. At the same time, it can also greatly reduce the flue gas temperature and reduce the heat loss of the boiler exhaust, thereby further improving the boiler thermal efficiency.
[0019] According to the actual operation, the equivalent available coefficients of #1 and 2 boilers are 92.63% and 94.6% respectively; the measured average values of thermal efficiency of #1 and 2 boilers are 93.26% and 93.56% respectively; the environmental protection emission values of boi...
