Abstract

The invention discloses a forecast system of sulfur dioxide in heating furnace flue gas, and a forecast method. The forecast system comprises a heating furnace and a nozzle arranged on the heating furnace; the system further comprises an air pipeline conveying mechanism for conveying air into the nozzle, a coal gas pipeline conveying mechanism for conveying the coal gas into the nozzle, and a coalgas detection analysis mechanism for detecting the coal gas compositions in the coal gas conveying mechanism. Through the forecast system disclosed by the invention, the coal gas desulfurization process production and the fuel use production control can be guided, thereby realizing ultra-low emission and reducing the enterprise desulfurization cost.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a forecasting system and a forecasting method for sulfur dioxide in flue gas of a heating furnace. Background technique [0002] As the form of environmental protection becomes increasingly severe, the requirements for environmental protection emissions become more stringent. As far as the emission limit of flue gas from steel rolling heating furnace in the steel industry is concerned, the "Work Plan for Ultra-low Emission Transformation of Iron and Steel Enterprises (Draft for Comment)" issued by the Ministry of Environmental Protection requires that: SO in the flue gas of steel rolling heating furnace 2 Will be by 150mg / Nm 3 down to 50mg / Nm 3 It is planned to be implemented nationwide by 2020. At present, some environmentally sensitive areas have issued and implemented corresponding local standards for ultra-low emissions. [00...
