Abstract

The utility model relates to a household coal heating stove, in which the inner wall cross section inside the heating cavity is rectangular. A fast hot assembly communicated to a water jacket is vertically arranged inside the heating cavity. A dust removal gate is arranged on the water jacket. The inside of the heating cavity can be provided with 2 to 3 layers of fast hot assemblies, and a vertical and horizontal cross-shaped layout is arranged in the upper and lower layer directions. The utility model is simple in structure with low cost. The heating surface is increased with the fast hot assembly. The heat absorption of the fast hot assembly structure is fast and complete. The ash scale on the fast hot assembly wall can be easily cleared after the dust removal gate is open, thereby a high efficient endothermic status of the fast hot assembly can be often maintained. The utility model has higher thermal efficiency with significant energy conservation, which can save coal by nearly 50% than general stoves.

Description

The residential coal combustion heating stove

The utility model relates to no pressure coal heating stove.

Civilian small heater stove has the market demand widely in northern China, particularly rural area samll cities and towns.At present, most of small heater stoves all are to develop on the basis of normal domestic use coal furnace, and are simple in structure, waste fuel, and outstanding shortcoming is that the heating surface of stove is little, the thermal efficiency is low, causes energy waste on the one hand, has increased user's financial burden on the one hand.

The purpose of this utility model is to provide the residential coal combustion heating stove of a kind of thermal efficiency height, energy savings.

The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises combustion chamber 7, water jacket 3, heating chamber 4, smoke exhaust pipe 1, delivery port 2 and water return outlet 8, heating chamber cross section of inboard wall of the present utility model is rectangular, vertically be provided with the fast hot box 5 and 6 that is communicated with water jacket in heating chamber, water jacket is provided with dedusting door 11.The speed heating box can be provided with 2～3 layers in heating chamber, every layer can be provided with a plurality ofly, and lower floor and upper strata direction can be cross-like in length and breadth.

The utility model is simple in structure, cost is low, and fast hot box has increased heating surface, and its structure heat absorption is fast and abundant, open the dedusting door, can clear up the black dirt on the fast hot box wall easily, make fast hot box often keep high efficiency heat absorption state, therefore, the utlity model has the higher thermal efficiency, energy savings is more remarkable, and test shows that comparable general stove economizes on coal nearly 50%.The dedusting door can also be used to regulating chamber temperature, when using stove to cook, the dedusting door can be opened a slit, reduces flue suction force, improves combustion chamber temperature.

Accompanying drawing 1 is the utility model structure (small size type) schematic diagram;

Accompanying drawing 2 is the utility model structure (large tracts of land type) schematic diagram;

Accompanying drawing 3 is the utility model profile schematic diagram.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.
