Abstract
The invention discloses a biomass anti-backfire feeding device which comprises a biomass feeder and an anti-backfire device. The biomass feeder is used for conveying biomass fuel falling down from a hopper into a biomass boiler. The anti-backfire device is arranged at a discharging outlet of the biomass feeder and comprises a material raising portion and a cover plate. The material raising portion is a hollow cylinder with the two ends provided with openings. One end of the material raising portion is communicated with the discharging outlet of the biomass feeder, and the cover plate is hinged to the other end of the material raising portion. The material raising portion inclines upwards, and the included angle alpha between the material raising portion and the horizontal plane ranges from 30 degrees to 50 degrees. In the using process, biomass fuel passes through the upward material raising portion and bursts through the cover plate to be scattered into a boiler combustion chamber in a parabolic shape. In the dynamic falling process, the biomass fuel makes full contact with air and is fully combusted, combustion efficiency is high, the combustion temperature is high, and burnout time is short. Moreover, through the upward material raising portion and the cover plate, the backfire phenomenon can be well avoided, and the purposes of guaranteeing the thermal efficiency of the boiler and improving safety are achieved.
