Abstract

The utility model relates to a household heating stove, in particular to an energy-saving reverse burning type household heating stove, which solves the problems of the prior reverse burning type household heating stove that since stack gases can not be fully burned, fuel waste and environment contamination are caused, and the powder coal can not be burned. The heating stove comprises a stove body in which a hearth and a flue are arranged, grate bars are fixed at the lower part of the hearth, a secondary wind supplying device is arranged on an outlet of the hearth, and the secondary wind supplying device comprises a wind supplying ring with an air outlet hole formed on the inner side thereof and a wind supplying tube which is fixed outside the wind supplying ring with one end thereof being communicated with an inner chamber of the wind supplying ring and the other end thereof penetrating the stove body communicated with the outside of the stove body; and the width of each grate bar is 12 mm, the thickness thereof is 40 mm, and the spacing thereof is 20 mm. The heating stove causes the stack gases to get full combustion at the part of the hearth outlet through adding the secondary wind supplying device, thereby realizing the energy conservation and emission reduction; and meanwhile, through the preference of the self size of the grate bar and the spacing thereof, and the match with the secondary wind supplying device, the heating stove can burn the powder coal with high tar content.

Description

Energy-conservation counter-burning type domestic heating stove

Technical field

The utility model relates to the domestic heating stove, is specially a kind of energy-conservation counter-burning type domestic heating stove.

Background technology

Existing counter-burning type heating stove comprises body of heater, be provided with burner hearth and flue in the body of heater, lower furnace portion is fixed with fire bars, and the position corresponding with stockhole is provided with and cooks and the heating switching device shifter on the flue, and switching device shifter comprises and is supported in the rotating shaft in the flue and is fixed in baffle plate in the rotating shaft; Have the exhaust opening that communicates with flue on the hearth wall of fire bars below.The end of rotating shaft is fixed with turning handle.During heating, thereby pull the rotating shaft in the turning handle rotation switching device shifter, rotating shaft drives the baffle plate motion, baffle plate blocking-up stockhole upwards, vent pathway through flue, flue gas in the burner hearth is downward at this moment, through fire bars, the exhaust opening of fire bars below and flue and discharge (promptly realizing anti-the burning), body of heater (or body of heater with water jacket) be heated and realize heating, volatile matter that initiate coal is at high temperature separated out and fuel gas, be fully burned through the flourishing layer of fuel, pass through simultaneously the filtration of ash bed again, flue does not have black smoke discharging substantially, has reduced exhaust smoke level and to the pollution of atmosphere.When cooking, the rotating shaft in the backward rotation switching device shifter makes exhaust opening under the baffle plate blocking-up fire bars through the vent pathway of flue.

When existing heating stove was used to cook, flue gas was accelerated at furnace outlet position flow velocity, formed negative pressure.Cause furnace outlet position anoxic, flue gas can not fully be burnt, not only waste fuel and contaminated environment.Simultaneously because fire bars size and the design of fire bars spacing are unreasonable, can not use the face coal when anti-burning work, can only burn contains the few high-quality lump coal of tar, along with the decline of this fat coal output, the price of coal is in recent years in continuous rise, and common people can't afford gradually to the price of this coal.

Summary of the invention

The utility model can not fully burn in order to solve existing counter-burning type domestic heating kiln gas, waste fuel, and contaminated environment and the problem that can not burn the face coal provide a kind of energy-conservation counter-burning type domestic heating stove.

The utility model is to adopt following technical scheme to realize: energy-conservation counter-burning type domestic heating stove, comprise body of heater, be provided with burner hearth and flue in the body of heater, lower furnace portion is fixed with fire bars, the place is provided with secondary air supply device at furnace outlet, and secondary air supply device has the benefit vane of venthole by its inboard and is fixed in mends the vane outside and an end communicates with benefit vane inner chamber, the other end passes body of heater and constitute with secondary air channel that body of heater is interlinked to the outside.During work, outer gas stream enters the furnace outlet position through secondary air channel, benefit vane, thereby realizes the secondary at furnace outlet position is mended wind, and flue gas is fully burned at the furnace outlet position, reaches fuel saving, reduces pollution problems.

Energy-conservation counter-burning type domestic heating stove described in the utility model, its fire bars width is 12mm, and fire bars thickness is 40mm, and the fire bars spacing is 20mm.Preferred by to fire bars self size and fire bars spacing makes heating stove described in the utility model can burn the face coal.Fire bars adopts and narrows down the high temperature resistant fire bars of thickening and reduced the fire bars spacing, thereby has reduced the burning resistance, and coal is fully burned.

Energy-conservation counter-burning type domestic heating stove described in the utility model can make flue gas be fully burned at the furnace outlet position by setting up the secondary air supply device that is made of benefit vane, secondary air channel, thereby realizes energy-saving and emission-reduction; Preferred by to fire bars self size and fire bars spacing cooperates secondary air supply device simultaneously simultaneously, makes the high face coal of this heating stove incendivity tar content, overcome original heating stove and can only burn the single problem that contains the few high-quality lump coal of tar.
