Embodiment Construction

[0014] As shown in the accompanying drawings, the biomass dense molding fuel combustion test bench of the present invention includes a base and a furnace arranged above the base, an electronic balance display device 1 is placed in the base, and an observation port is provided on the front of the base corresponding to the display screen of the electronic balance 2. The display value of the electronic balance can be observed from the observation port. There is a ventilation pipe on one side of the base, and a valve 11 is provided at the end of the ventilation pipe adjacent to the base to control the gas flow rate. An oxygen inlet 13 and a nitrogen inlet 14 are arranged outside the valve 11, and a gas inlet 13 is arranged between the valve 11 and the oxygen inlet 13. The mixing box 12 is provided with a fan 15 at the end of the air duct. The electronic balance stage 3 is placed in the furnace, the furnace is connected to the base, the inner wall of the furnace is provided with a ...

Abstract

The invention discloses a biomass briquette combustion test bed, which comprises a base and a hearth arranged above the base. An electronic balance display device is arranged in the base, the position, which corresponds to an electronic balance display screen, of the front face of the base is provided with a viewing port, one side of the base is provided with an aeration pipeline, one end, which is near the base, of the aeration pipeline is provided with a valve, and the outside of the valve is provided with an oxygen inlet and a nitrogen inlet; and an electronic balance object stage is arranged in the hearth, the hearth is communicated with the base, the inner wall of the hearth is provided with a resistance heater, one side of the hearth is provided with a temperature-measuring insertionhole, the top of the hearth is provided with a thermal insulation upper furnace door, and an exhaust pipeline is arranged above the hearth. The biomass briquette combustion test bed can allow for thereading of the dynamic mass of briquettes through the display of an electronic balance in the base at any time, and for the reading of the temperature in the hearth by a thermocouple inserted into the hearth. A smoke exhaust pipe is provided with a flue gas sampling port, a flue gas flow velocity measurement insertion hole and a temperature measurement port and can analyze the indexes of flue gassuch as components, flow velocity, temperature and the like.

Description

technical field [0001] The invention relates to a biomass dense molding fuel combustion test bench. Background technique [0002] Biomass compression molding technology is to compress biomass waste such as straw, rice husk, sawdust and wood chips into a solid molding fuel with a certain shape and high density by mechanical pressurization. The fuel is easy to be accepted by people because of its advantages of high thermal efficiency, long-lasting vitality, cleanness and environmental protection, and convenient transportation and storage. The microstructure analysis and combustion mechanism research of biomass compact briquette fuel is the basis for realizing the efficient combustion and rational utilization of biomass compact briquette fuel, and it is also the theory for realizing safe, stable and economical combustion of biomass compact briquette fuel combustion equipment and reasonable arrangement of heating surfaces At the same time, it provides a scientific basis for the...
