The invention relates to the technical field of biomass equipment, in particular to a multilayer combined type combustor for the biomass equipment. The multilayer combined type combustor for the biomass equipment comprises a combustor body. The combustor body comprises a cylindrical furnace shell, and the top of the furnace shell is provided with a pot. A first-stage combustion bin is arranged inthe middle in the furnace shell. The first-stage combustion bin comprises an annular face, a first frustum-shaped side wall inclining inwards is arranged on the periphery of the bottom of the annularface, and the edge end of the bottom of the first frustum-shaped side wall is provided with a bottom combustion bin face. The middle of the bottom combustion bin face is an arc-shaped protruding filter net which arches upwards, and an annular filtering groove net which is concaved inwards is formed between the periphery of the bottom combustion bin face and the edge end of the bottom of the firstfrustum-shaped side wall. The multilayer combined type combustor for the biomass equipment is convenient to use, simple in structure and low in cost, the maximum combustion can be reached, maximum heat energy generation can be formed, the combustion efficiency of the multilayer combined type combustor is greatly improved, waste is reduced, and the requirement for energy saving and environment protecting of the present society is met.
