An experimental device for studying mixed combustion of pulverized coal and biomass

Abstract

The invention belongs to the field of thermal energy engineering equipment, and specifically discloses an experimental device for studying the mixed combustion of coal powder and biomass, which includes: a main body assembly of a furnace, which is used to provide the space and heat required for combustion. There is a combustion tray assembly; a powder feeder assembly, which is connected to the furnace body assembly and is located above the combustion tray assembly; a gas supply assembly, which is connected to the powder feeder assembly and the furnace body assembly; a cooling assembly, which is connected to the powder feeder assembly connected to provide cooling medium for it; exhaust gas analysis and processing component, which is connected to the main component of the furnace, used to analyze and process the combustion exhaust gas; photographing and temperature measurement component, which is located next to the main component of the furnace, used for shooting Fuel combustion image and measurement of fuel flame temperature; electrical control box assembly, which is used to power other components. The invention can not only capture the interaction between biomass and pulverized coal in mixed combustion, but also detect the flame temperature and gas products in the ignition and combustion process.

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...

Problems solved by technology

The existing dropper furnace device is only suitable for the study of the ignition and combustion behavior of a single fuel, and it is difficult to accurately capture and distinguish the two types of fuel for mixed combustion, let alone study the interaction between the two
