Abstract

The invention belongs to the field of heat energy engineering equipment, and particularly discloses an experimental device for researching blending combustion of pulverized coal and biomass. The experimental device comprises a furnace body assembly used for providing space and heat required by combustion, wherein a combustion tray assembly arranged in the furnace body assembly; a powder feeder assembly connected with the furnace body assembly and positioned above a combustion tray assembly; a gas supply assembly connected with the powder feeder assembly and the furnace body assembly; a coolingassembly which is connected with the powder feeder assembly and provides a cooling medium for the powder feeder assembly; a tail gas analyzing and processing assembly which is connected with the furnace body assembly and is used for analyzing and processing the combustion tail gas; a shooting and temperature measuring assembly which is arranged beside the furnace body assembly and is used for shooting a fuel combustion image and measuring the fuel flame temperature; and an electric control box assembly which is used for supplying power to other assemblies. The interaction in the blending combustion of biomass and pulverized coal be captured, the flame temperature and gas products in the ignition and combustion process can be detected.

Description

technical field [0001] The invention belongs to the field of thermal energy engineering equipment, and more specifically relates to an experimental device for studying mixed combustion of coal powder and biomass. Background technique [0002] Excessive exploitation and use of fossil fuels will cause resource depletion and produce a large amount of pollutants, such as SOx, NOx and CO 2 These pollutants will cause a series of environmental problems such as acid rain and greenhouse effect, and seriously endanger human life and property safety. Biomass energy is a clean and renewable energy with abundant raw materials and low production cost, so it is regarded as an important alternative fuel to fossil fuels. Biomass absorbs CO during photosynthesis 2 CO released from the combustion process 2 Form a "carbon balance", is CO 2 Zero-emission fuel, and low sulfur content in biomass, can effectively reduce SO 2 emissions. Therefore, burning biomass mixed with pulverized coal ha...
