The most preferred embodiment of the high-efficiency energy-saving heating stove course of work:

The utility model adopts double-deck burning, spin slot formula heat dump, the secondary eddy flow new construction to hot blast, steam added combustion device and 3-stage dust-removal, and realization can be efficient, energy-conservation, smoke abatement and dust control, design philosophy that the thermal efficiency is high.

The ground floor burning is carried out on moving grate, is covered with flame-proof thermal insulation material owing to adopt on spherical hearth and the thorax, has improved fire box temperature; Adopt cellular secondary fire grate to improve radiation of burner hearth heat, guaranteed that the coal oxidation reaction is temperature required; The secondary hot-air that comes out by pre-hot bellows, secondary air channel and circle of contact tuyere forms rotating pit type hot blast stream in lower combustion chamber, guaranteed air capacity suitable in the oxidizing process; Therefore prolong the holdup time of high-temperature flue gas in burner hearth, improved efficiency of combustion.

Second layer burning is carried out on the secondary fire grate, because the burning in the lower combustion chamber, make secondary fire grate temperature higher, satisfy the carbon monoxide that produces in reduction and the water decomposition process the combustion temperature, therefore, combustion-supporting secondary fire grate plays high-temperature flue gas is evenly spread, and fuel gas is contacted with oxygen with the catalyst water vapour that the steam added combustion device provides again, and impels oxidation reaction fully to carry out once more on the secondary fire grate; And fuel gas is fully burnt, played the first smoke abatement and dust control effect.

In the two-layer heat-exchange device of upper furnace body, clean-burning high-temperature flue gas, lowered the temperature through two-stage spin slot formula heat dump, finish heat exchange, most of dust being fallen into dropped clearly on the plate of deduster on grate once more through two-step filter again, burning is discharged to grey chamber with cinder at last, this two-layer heat exchange dust arrester has been finished heat exchange, flue gas ash removal, contraction, the cooling of the high-temperature flue gas that heating is provided, at last being discharged out of the furnace by the top chimney of task.
