A kind of coal-fired boiler in power plant smoke emissioning pollution thing controls process unit and control method, includes the flue gas heat recovery system that coal gasification system is connected and cleaning system three part being connected with flue gas heat recovery system with coal gasification system；Coal gasification system is used for producing fuel gas with low heat value, removes the SO in flue gas under the rear portion synthesis gas effect of the boiler in flue gas heat recovery system X 、NO X , remove the heavy metal in flue gas and halogen by cleaning system.It is simple and easy to get that the present invention has raw materials technology, does not produce secondary pollution, and pollutant removing efficiency is high, the advantage that pollutant removing efficiency is not affected by smoke components, can realize high efficiency synchronous removing NO X 、SO X , halogen, hydrargyrum, lead, chromium, the purpose of the flue gas pollutant such as arsenic. |
