Problems solved by technology

[0002] At present, there is a problem that straw bales cannot be fully burned and burned in existing straw bales burning direct-fired biomass boilers. The reason is that straw bales in the existing boilers are naturally burned by blower air, which not only burns slowly, but also does not burn completely. In addition, if the moisture in the straw seriously exceeds the standard, the straw will not be able to burn out in the furnace, which leads to the disadvantages of slow temperature rise and low thermal efficiency in the existing straw-bundled direct-fired biomass boilers.

Abstract

The invention discloses a straw bundle burning direct-fired biomass boiler with a bale breaking and material stirring device. The straw bundle burning direct-fired biomass boiler comprises a bale breaking roller assembly and a material stirring roller assembly, wherein the bale breaking roller assembly is positioned in a straw bale breaking chamber or a hearth of the boiler and comprises one or two rotatable bale breaking roller main shaft pipes; a water cooling channel or an air cooling channel is arranged in each bale breaking roller main shaft pipe; a plurality of bale breaking thorns are arranged on the annular outer wall of each bale breaking roller main shaft pipe; the material stirring roller assembly is positioned in the hearth of the boiler and comprises one or two rotatable material stirring roller main shaft pipes; a water cooling channel or an air cooling channel is arranged in each material stirring roller main shaft pipe; and a plurality of material stirring thorns are arranged on the annular outer wall of each material stirring roller main shaft pipe. The straw bundle burning direct-fired biomass boiler solves the problem of straw bundle direct burning, straw bundlescan be sufficiently burnt out in the boiler, the temperature of the boiler is increased fast, and heat efficiency is high; and meanwhile the structures such as the bale breaking roller assembly, thematerial stirring roller assembly and corresponding rotating bearing pedestals cannot be damaged due to the fact that the structures are in a high-temperature state for a long time.

Description

technical field [0001] The invention relates to the technical field of straw bundling and burning, in particular to a straw bundling burning direct-fired biomass boiler with a bag breaking and feeding device. Background technique [0002] At present, there is a problem that the straw bales cannot be fully burned in the existing direct-fired biomass boilers. The reason is that the straw bales are naturally burned by the blower in the existing boiler, not only the burning speed is slow, but also the combustion is not complete. In addition, if the moisture in the straw exceeds the standard seriously, the straw cannot be burned out in the furnace, which leads to the disadvantages of slow temperature rise and low thermal efficiency in the existing straw-bundled direct-fired biomass boilers. [0003] Therefore, how to solve the technical shortcomings of the existing straw-bundled direct-fired boilers and provide a straw-bundled direct-fired biomass boiler that can be fully burned ...
