Multi-fuel heating furnace

Abstract

A multi-fuel heating furnace comprises a furnace body provided with a hearth inside. An ash bucket is disposed below the hearth. The upper portion of the furnace body is provided with a chimney holder and a feed hole communicated with the hearth. The hearth is provided with an internal compartment communicated with the hearth. The compartment houses a thermoelectric blower which is provided with a switch and which is disposed on the inner wall of the compartment. Both the compartment and the furnace body are provided with a plurality of pores allowing the thermoelectric blower to suck in air. The multi-fuel heating furnace has the advantages that combustion can be subjected to blow pressurizing to achieve thorough combustion and higher heating amount; the switch for controlling the thermoelectric blower to start and stop is provided, the thermoelectric blower is stopped when not needed, fire sealing time is longer, and continuous combustion is achieved; operation of the thermoelectric blower allows the furnace to well combust in the area lower than 4500m in altitude, and the furnace is well adaptable to high altitudes and high in heat efficiency; the multi-fuel heating furnace is also applicable to flat areas and is low in production cost, low in application and maintenance costs and stable and reliable in performance.

Description

technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a multi-fuel heating furnace. Background technique [0002] At present, when camping in the wild for heating, the plain type coal firewood heating stove is mainly used in the living tent. The stove uses coal, firewood, dry animal manure, etc. as fuel. When used in plateau areas above 4000m, there are problems of incomplete combustion, serious heat supply attenuation, short fire closure time, and even continuous combustion cannot be maintained. For tents with a large indoor area, plateau heating is mainly solved by plateau fuel heaters. However, for tents with a small area and fewer residents, the use of fuel heaters for heating has problems such as high investment costs and high operating costs. Therefore, the heating problem of small-area tents in plateau areas has not been well solved for many years. Contents of the invention [0003] The object of the present i...

Problems solved by technology

[0002] At present, when camping in the wild for heating, the plain type coal firewood heating stove is mainly used in the living tent. The stove uses coal, firewood, dry animal manure, etc. as fuel. When used in plateau areas above 4000m, there are problems of incomplete combustion, serious heat supply attenuation, short fire closure time, and even continuous combustion cannot be maintained

For tents with a large indoor area, plateau heating is mainly solved by plateau fuel heaters. However, for tents with a small area and fewer residents, the use of fuel heaters for heating has problems such as high investment costs and high operating costs.

Therefore, the problem of heating small area tents in plateau areas has not been well solved for many years.
