Heating furnace provided with heat conducting device

Abstract

The invention provides a heating furnace provided with a heat conducting device. The heating furnace comprises an inner housing and an outer housing; the inner housing is internally provided with a combustion chamber; a fan is arranged inside a cavity between the inner housing and the outer housing; the rear part of the inner housing is provided with a rear heat absorbing chamber; an air inlet ofthe rear heat absorbing chamber is connected with an air blowing opening of the fan; the combustion chamber is further internally provided with a hot air tube; the air inlet of the hot air tube is formed in the inner wall of the rear heat absorbing chamber; an exhausting opening of the hot air tube extends to a hot air exhausting opening of the heating furnace; the two sides of the inner housing are further each provided with a side heat absorbing chamber; the lower parts of the side heat absorbing chambers communicate with the rear heat absorbing chamber; and the air outlet of the rear heat absorbing chamber and the air outlets of the side heat absorbing chambers all communicate with the hot air exhausting opening of the heating furnace. The heating furnace provided with the heat conducting device realizes heat exchange by virtue of the rear heat absorbing chamber, also realizes heat exchange by virtue of the hot air tube and the side heat absorbing chambers, increases the heat absorption area in comparison with the heat exchange realized by the rear heat absorption chamber only, and greatly increases the heat utilization rate.

Description

Technical field [0001] The invention relates to a heating stove, in particular to a heating stove with low exhaust gas temperature and capable of effectively using combustion heat. Background technique [0002] Existing heating stoves usually have a heat absorption cavity at the back of the combustion chamber. The heat is transferred to the heat absorption cavity through the back wall of the combustion chamber, that is, the back wall of the inner casing, and then the fan blows out the hot air in the heat absorption cavity. However, after monitoring, it was found that the exhausted flue gas was still at a relatively high temperature, and the high-temperature flue gas was exhausted outdoors, resulting in low combustion heat utilization. Summary of the invention [0003] In order to solve the problems of high exhaust gas temperature and low combustion heat utilization rate when only a heat absorption cavity is provided at the rear of the combustion chamber in the prior art, the prese...
