AI Technical Summary

Problems solved by technology

These coal furnaces are relatively old, and the furnace lining is generally made of mud. Due to the unreasonable design of the furnace lining structure, the coal cannot be fully burned, and a large amount of fine coal powder and combustible gas are discharged from the chimney, which wastes energy and pollutes the environment.

Embodiment Construction

[0013] As shown in Figure 1, the furnace lining 7 is made of pottery clay or inorganic refractory material directly on the inner wall of the furnace body 11 to form a hollow furnace 10 with a bell mouth shape with a large bottom and a small top; the inner wall of the furnace lining 7 has a bottom air inlet 8 from bottom to top. There is a side wall air inlet 9 that penetrates the furnace lining wall on the outer wall of the furnace lining 7; there is a raised part near the smoke outlet 6 on the upper part of the furnace lining 7 as a fire wall 5; The unclosed combustion circle 3, the unclosed part of the combustion circle 3 sandwiches the raised fire-retaining wall 5, the distance between the upper edge of the combustion circle 3 and the burner basin 2 is 15mm; four steel bars with a height of 19mm are welded under the combustion circle 3 Support 4, steel bar support 4 is placed on furnace lining 7.

Abstract

An energy-saving combustion method without smoke for coal stove features that the mixture of powdered coal and combustible gas is burning in vortex mode in a high-temp combustion chamber consisting of upper stove basin, non-closed combustion ring, supporting frame, fire wall and the top opening of stove liner. Its combustion apparatus is composed of stove cover, upper stove basin, smoke outlet, fire wall, stove liner, combustion box, stove body, grate and ash storing base.

Description

technical field [0001] The invention belongs to the technical field of combustion, and more specifically relates to a combustion method and a combustion device of a household coal stove. Background technique [0002] At present, many residents in rural areas and small towns in northern my country still use simple coal stoves that burn coal slime and loose coal for heating, boiling water, and cooking in winter. These coal furnaces are relatively old, and the furnace lining is generally made of mud. Due to the unreasonable design of the furnace lining structure, the coal cannot be fully burned, and a large amount of fine coal powder and combustible gas are discharged from the chimney, which wastes energy and pollutes the environment. The simple coal furnace feeds coal from the furnace mouth, coal preheating, high-temperature combustion, and smoke emission are all here. From the point of view of the combustion principle, the preheating zone and the high-temperature combustion z...
