Abstract

The utility model relates to a household furnace used in the countryside, in particular to a biomass hot water cooking gasification furnace which solves the problems like uneasy control of air supply volume of air supply structure, unreasonable up and down air inlet proportioning, complex structure and operation, etc, of the current gasification furnace. The biomass hot water cooking gasification furnace includes a furnace body, an ashpan arranged above the furnace body and an insulating sleeve arranged in the furnace body; the inside of the insulating sleeve is provided with a combustion room, a gasification room and an ash collection room in sequence; the gasification room and the ash collection room is separated by a furnace grate; a secondary air supply room communicated with the top part of the combustion room is formed between the insulating sleeve and the furnace body; an air bellow is arranged below the furnace body; the air outlet of the air bellow is communicated with the secondary air supply room; the inside of the ash collection room is provided with a pull type ash collection hopper which is matched with the ash collection room; and one side of the ashpan is provided with a hot water tank integrally manufactured with the ashpan. Both the first air supply volume and the secondary air supply volume can be adjustable; the biomass hot water cooking gasification furnace can realize the optimal combustion effect through reasonable up and down air inlet proportioning, has a simple structure, is convenient to be operated, and adopts the hot water tank to sufficiently use the heat energy generated during the combustion of gases.

Description

Biomass hot water cooking gasification furnace

Technical field

The utility model relates to a kind of rural area Domestic stove, is specially a kind of biomass hot water cooking gasification furnace.

Background technology

Along with improving constantly and the continuous reinforcement of environmental consciousness of people's living standard, various biomass gasifying furnaces have appearred in the market, it is to utilize living beings (as: agricultural waste material such as stalk, rice husk, branch, weeds or house refuse etc.) to burn under anaerobic condition, make most of combustible species be converted into fuel gas, use for cooking.In said process, all can be equipped with the air feed structure when living beings gasification and gas fuel burning, but an existing air feed structure and secondary air feed structure exist all that wind supply quantity is wayward, the air intake proportioning is unreasonable and cause combustion instability, influence the problem of gasification result up and down, and air feed structure more complicated, volume greatly, complicated operation, use inconvenience.In addition, existing rural area is more single with the gasification furnace function ratio, and the heat energy that produces during gas fuel burning fails to be fully used.

Summary of the invention

The utility model provides a kind of biomass hot water cooking gasification furnace in order to solve wayward, the problems such as the unreasonable and complex structure of air intake proportioning, complicated operation up and down of existing gasification furnace air feed structure wind supply quantity.

The utility model is to adopt following technical scheme to realize: biomass hot water cooking gasification furnace, comprise the body of heater that is fixed on the furnace bottom, be positioned at the ashpan of body of heater top and the insulation sleeve that is positioned at body of heater, be provided with the combustion chamber from top to bottom successively in the insulation sleeve, vaporizer and dust collection chamber, separate by fire grate between vaporizer and the dust collection chamber, innovative point of the present utility model is to be incubated between sleeve and the body of heater and constitutes the secondary air supplying chamber that communicates with top of combustion chamber, bellows are equipped with in the body of heater below, the air outlet of bellows is communicated with secondary air supplying chamber, is provided with the drawing and pulling type flue-dust retainer that cooperatively interacts with it in the dust collection chamber.Described bellows are made of the drive unit of blower fan and the rotation of control blower fan usually, are existing known products.

Described ashpan one side is provided with the boiler of making one with it, when gasification furnace is being used for the process of cooking, the heating of the water in the ashpan one side boiler can have been made full use of waste heat.

Adopt structural design of the present utility model, regulate a wind supply quantity (being living beings gasification time institute's required airflow) by the folding degree of drawing and pulling type flue-dust retainer, regulate secondary wind supply quantity (oxygen demand when being gas fuel burning) by bellows, by air intake rational proportion up and down, make burning reach optimum efficiency, simple in structure, easy to operate, realized that furnace temperature and intake are controlled, carry out different air distributions in each burning period, realized the gasification of fixed carbon, the raising of combustion thermal efficiency has been had the meaning of breakthrough; In addition, the heat energy that the utility model produces when adopting boiler with gas fuel burning is fully used, and has effectively utilized waste heat, is user-friendly to.
