The purpose of this utility model provides a kind of when continuing new coal or ash disposal, does not influence continuous result of use, and furnace temperature is stable, over-emitting black exhaust not, energy-efficient new-type domestic type coal stove.

Below, in conjunction with the accompanying drawings, design of the present utility model is described in detail:

Accompanying drawing 1, be the schematic diagram of the utility model front view.

Accompanying drawing 2, be along the A-A cross sectional plan view.

Accompanying drawing 3, be the partial sectional view of A after removing fire door and furnace shell.

The technical solution of the utility model is such: burner hearth 3 is made tunnel type, its front has fire door 8, open a fire output hole 6 in the burner hearth front top, as flame export, this is provided with fire-regulating plate 5 and the fire door 7 that can adjust flame intensity above outlet, be provided with flue 4 at the fire door side and be connected with chimney, be respectively equipped with the slideway 1 that the cross section is the Contraband type in the bottom of burner hearth both walls, the slideway two ends are fixed on support or the furnace shell. Be equipped with the port comb 2 that several width are slightly larger than the moulded coal bottom surface on this slideway, the two ends of this fire grate are embedded in the Contraband type slideway, can Slide along slideway, this fire grate is inserted slideway by fire door 8, can extract out from the end of slideway or the corresponding wicket 9 of side, and the following of fire grate be air compartment and grey chamber, and the burner hearth both sides are provided with heat-insulation layer 12 and metal furnace shell 11, and ash 10 is located at the rear side lower part of burner hearth.

The utility model is placed on moulded coal (Sequare honeycomb briquet or coal briquette) earlier on the port comb 2 in use, and fire door 8 is opened, with a carriage of holding of manufacturing separately fire grate 2 and moulded coal are advanced burner hearth 3 along slideway 1 together, then advance again second, third piece, until slideway is occupied, close upper furnace door.
