Air outlet pipe of biomass burning furnace and burning furnace

Abstract

The invention discloses an air outlet pipe of a biomass burning furnace and a burning furnace. A plurality of straight air pipe side air outlets are uniformly distributed in a top pipe body of a straight air pipe on the same circumference and a relative large sheet straight air pipe cap is arranged on a top end face of the straight air pipe. The air outlet pipe of the biomass burning furnace and the burning furnace have the following beneficial effects: an air distribution pipe of an annular air duct also is of a cone-shaped annular structure as a whole; the plurality of straight air pipe side air outlets are uniformly distributed in the top pipe body of the straight air pipe on the same circumference and the relative large sheet straight air pipe cap is arranged on the top end face of the straight air pipe, and such a structure of the straight air pipe is capable of distributing air more uniformly on the same horizontal plane within a hearth; and a plurality of bent air pipe side air outlets are uniformly distributed in a pipe body, in a bend direction, of the top of a bent air pipe on the same semi-circle, and such a structure of the bent air pipe is capable of uniformly jetting air to the central position of the hearth, and therefore, air may be distributed more uniformly in the middle of the hearth.

Description

technical field [0001] The invention belongs to a solid fuel combustion furnace, and relates to a fully automatic feed biomass combustion furnace in which the fuel is combusted from top to bottom, in particular to a biomass combustion furnace air outlet pipe and a combustion furnace. Background technique [0002] The air outlet direction of the air outlet holes in the furnace of the existing biomass combustion furnace is consistent with the axis direction of the air outlet pipe, and there is only one air outlet, which causes the oxidant (air) to concentrate on the local combustion of the fuel, which increases the concentration of the fuel during the combustion process. The possibility of slag seriously affects the working performance of the combustion furnace. [0003] Therefore, the prior art scheme also needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to provide a biomass combustion furnace air outlet pipe and a co...
