Clean combustion heating stove for civil use

Abstract

The invention provides a clean combustion heating stove for civil use. The clean combustion heating stove for civil use comprises a hearth, a fire grate, an ash hopper, a primary air inlet and a chimney; the chimney is provided with a waste heat recycling box; and a plane heat exchange water jacket is arranged on the upper portion of the hearth. According to the improvement of the innovative structure, a cylindrical air supply cavity formed by an inner air ring, an outer air ring and a lower end face is arranged at the lower center of the plane heat exchange water jacket; the outer air ring and the inner air ring are tangential and are provided with an outer ventilation hole and an inner ventilation hole in a staggered manner; the lower end face of the air supply cavity is closed or is provided with an end face ventilation hole; and a secondary air inlet pipe is introduced from the exterior of the hearth and is connected to the cylindrical air supply cavity. According to the clean combustion heating stove for civil use, by means of the structural improvement, the hearth is internally divided into three combustion spaces for tertiary air inflow combustion supporting, air is supplied for volatile components which are obtained when fuel is heated and separated out but is not combusted in time for combustion supporting, after combustible substances are sufficiently combusted many times, the heat converting efficiency is substantially improved, and combustible materials and pollutants contained in exhausted smoke are reduced, so that the pollution discharge problem caused when combustion of a civil use fuel coal stove is not complete can be solved.

Description

technical field [0001] The invention relates to a clean burning civil heating stove, which belongs to the technical field of civil heating and dust removal. Background technique [0002] Residents in northern rural areas and surrounding cities and towns generally use civilian stoves to burn loose coal for heating in winter, causing serious emissions of pollutants such as smoke and dust. For example, there are about 50,000 rural areas in Hebei, more than 15 million peasant households, which dissipate 28 million tons of coal annually, emit 268,800 tons of particulate matter, 462,000 tons of sulfur dioxide, and 436,800 tons of nitrogen oxides. Statistics show that pollution from scattered coal burning in rural areas of Hebei contributes 30% to the province's air pollution. Burning 1 ton of loose coal in rural areas emits more pollutants than burning 50 tons of coal in power plants. [0003] The ubiquitous problems of existing civil heating stoves include the following aspects...
