#$%^&*AU2020102185A420201015.pdf#####Abstract The present invention discloses a straw bale direct-burning biomass boiler with bale breaking and feeding devices. The straw bale direct-burning biomass boiler includes a bale breaking roller assembly and a feeding roller assembly. The bale breaking roller assembly is positioned in a straw bale breaking chamber or a hearth of the boiler and includes one or two rotatable bale breaking roller spindle tubes; a water-cooling channel or an air-cooling channel is formed in each of the bale breaking roller spindle tubes; annular outer walls of each bale breaking roller spindle tube are provided with a plurality of bale breaking thorns; the feeding roller assembly is positioned in the hearth of the boiler and includes one or two rotatable feeding roller spindle tubes; a water-cooling channel or an air-cooling channel is formed in each of the feeding roller spindle tubes; and annular outer walls of each feeding roller spindle tube are provided with a plurality of feeding thorns. The present invention solves the direct burning problem of the straw bales, so that the straw bales may be well burned out in the boiler, a temperature of the boiler is rapidly increased, and thermal efficiency is high. Meanwhile, the bale breaking roller assembly, the feeding roller assembly and corresponding rotary bearing seats are prevented from being damaged even if in a high-temperature state for a long time.Drawings of Description 3 2 4 1: Fig. 1 1
