Abstract
The utility model relates to a hearth of a biomass fuel vaporizing combustion furnace. The hearth comprises a hearth jacket and a grate at the bottom thereof, a sliding door and an ash case which are arranged below the grate, and a feeding opening and a feeding door which are arranged at the upper part of the grate, wherein a fireproof tube is arranged above the grate so as to bear a gas ring, and a heat-insulation layer is arranged between the fireproof tube and the hearth jacket. The gas ring is gradually narrowed upwards, and more than one row of secondary air holes distributed evenly is arranged at the periphery of the gas ring. When the hearth is in working, biomass fuel is stuffed on the grate of the hearth for burning through the feeding opening; the sliding door is operated so as to control air supply amount and promote reducing fire of the fuel to generate combustible gas; the combustible gas can be combusted with the help of air permeating from the secondary air holes; when the fuel finishes generation of the gas, the sliding door is adjusted to continuously combust coke till the coke is after-combusted; the heat accumulation function of the fireproof tube is contributive to reliable fuel and stable combustion; and the heat insulation action of the heat-insulation layer is contributive to reliable fire banking and fast starting of the hearth. The hearth can burn out volatile and coke for one time.
Description
Technical field
The utility model relates to the household solid-fuel furnace kitchen range, biomass fuel gasifying burning home furnace particularly, the burner hearth parts of especially described cooking stove.
Background technology
Vast farmers and Lin worker, always heating is gathered materials on the spot, cooked to custom; The household kitchen range of research biomass fuel, for saving faggot, protection forestry, developing agricultural, purification room, protection environment, saving fossil energy, significant.
The volatile matter of low heat value biomass fuel accounts for 70% greatly, coke accounts for 30% greatly, carries out gasification and combustion integrative, burnout volatile matter and coke, is the basic outlet that improves fuel efficiency, minimizing soot emissions.
Gasification is a burner hearth with the core component of combustion integrative.The shortcoming of common burner hearth is: heat dissipates big, and it is low that the bottom of a pan gets the thermal efficiency; Fire box temperature is low, and thick bavin difficulty is grilled thoroughly, and wet bavin can not burn; Furnace temperature fluctuation is big, and it is difficult to start, and it is difficult to quicken, the difficulty of banking up a fire.
Summary of the invention
In order to improve furnace temperature, reduce hear rate, adaptation is banked up a fire, and the utility model provides a kind of simple, suitable, economic burner hearth.
The technical scheme that its technical problem that solves the utility model adopts is: the burner hearth that designs a kind of biomass fuel gasifying burning cooking stove, the fire grate that comprises burner hearth cover and bottom thereof, sliding door below the fire grate and grey case, the feeding port on fire grate top and filler door, being that refractory tube is accepted the combustion gas circle above the fire grate, is insulating tube or insulation filler between refractory tube and the burner hearth cover.The combustion gas circle upwards dwindles gradually, and the above equally distributed secondary air hole of a row is arranged on every side.
The operation principle of the utility model burner hearth is: in burner hearth when work,, biomass fuel is filled in through feeding port on the fire grate of burner hearth and is burnt; The operation sliding door, air quantity is given in control, impels the fuel anoxycausis to produce fuel gas; The air-breathing that fuel gas advances thoroughly by secondary air hole; When the fuel aerogenesis finishes, regulate sliding door coke is burnt away, until after-flame; The heat accumulation function of refractory tube is facilitated reliable, the burn steadily of fuel; The insulation effect of heat-insulation layer facilitates burner hearth reliably to bank up a fire, start fast.This burner hearth can once burnout volatile matter and coke.
The beneficial effect of the utility model burner hearth is: abundant refractory tube, have good heat storage performance, and be convenient to provide fire box temperature, facilitate reliable, the burn steadily of fuel; The insulation effect of heat-insulation layer facilitates burner hearth reliably to bank up a fire, start fast, reduces hear rate; Refractory tube, heat-insulation layer and sliding door synergy can be controlled furnace temperature fluctuation, solve difficult problems such as starting difficulty, acceleration difficulty, the difficulty of banking up a fire.

Sequence number among the figure: 21 burner hearth covers, 22 fire grates, 23 refractory tubes, 24 combustion gas circles, 25 insulating tubes, 26 secondary air holes, 27 feeding ports
The specific embodiment
As shown in the figure, a kind of burner hearth of biomass fuel gasifying burning cooking stove, the fire grate (22) that comprises burner hearth cover (21) and bottom thereof, sliding door and grey case below the fire grate (22), the feeding port (27) and the filler door on fire grate (22) top, being that refractory tube (23) is accepted combustion gas circle (24) above the fire grate (22), is insulating tube (25) between refractory tube (23) and the burner hearth cover (21).Combustion gas circle (24) upwards dwindles gradually, and the above equally distributed secondary air hole (26) of a row is arranged on every side.The secondary air hole (26) of corresponding combustion gas circle (24), burner hearth cover (21) and insulating tube (23) are provided with secondary air hole (26); Combustion air passes the secondary air hole (26) of burner hearth cover (21), insulating tube (23), combustion gas circle (24), with the interior fuel gas mixed combustion of combustion gas circle (24).
During burner hearth work, the fire grate (22) that biomass fuel is filled in burner hearth through feeding port (27) is gone up burning; The operation sliding door, air quantity is given in control, impels the fuel anoxycausis to produce fuel gas; The air burning that fuel gas advances thoroughly by secondary air hole (26); When the fuel aerogenesis finishes, regulate sliding door coke is burnt away, until after-flame; The heat accumulation function of refractory tube (23) is facilitated reliable, the burn steadily of fuel; The insulation effect of insulating tube (25) facilitates burner hearth reliably to bank up a fire, start fast.This burner hearth can once burnout volatile matter and coke.
Claims (5)
1. the burner hearth of biomass fuel gasifying burning cooking stove, the fire grate that comprises burner hearth cover and bottom thereof, and the feeding port and the filler door on the sliding door below the fire grate and grey case, top, it is characterized in that, being that refractory tube is accepted the combustion gas circle above the fire grate, is insulating tube or insulation filler between refractory tube and the burner hearth cover.
