Secondary combustion stove

Abstract

The invention discloses a secondary combustion stove which comprises a stove cover, a combustion air supply pipe, a combustion chamber, a movable cover plate, an air pipe, an ash door, an ash chest, an ash cleaning opening, an evaporation chamber, a residual heat water jacket, a flue pipe, a watering hopper, an air outlet pipe, a circulating pipe, a water outlet nozzle, a bolt plug, a blower and a valve. The secondary combustion stove is characterized in that the residual heat water jacket is arranged on the outer side on the periphery of the combustion chamber; a cooker is mounted in the middle of the combustion chamber; the flue pipe is mounted on the rear side at the top of the combustion chamber; the combustion air supply pipe is arranged on the side edge of the combustion chamber; the combustion air supply pipe and the blower are arranged at the lower part of the combustion chamber. According to the secondary combustion stove, the blower is adopted to supply air for the combustion air supply pipe and the air is supplied to the combustion chamber for combustion-supporting, the secondary air supply is achieved; the structure is simple, the floor space is small, the use is convenient and simple, cleanness and sanitation are realized and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to a stove, in particular to a secondary combustion stove using biomass such as crop stalks, cattle and sheep dung as fuel. Background technique [0002] Existing stoves mostly use one pot and one stove to burn firewood and stick boards. However, with the improvement of people's living standards, firewood and wood boards are not allowed to be used as fuel, and biomass such as straw, cattle and sheep dung in rural crops has become the majority The main fuel in rural and pastoral areas is smoky, unhygienic and inconvenient, and its utilization efficiency is low. In order to improve the living environment of farmers and herdsmen, make full use of renewable biomass energy such as crop stalks, cattle and sheep dung in rural pastoral areas, change the combustion mode, install a flat pad utilization device around the ring of the stove, and add secondary energy to the furnace Combustion wind supports combustion, improves utilization effi...
