Description

Controllable fast starting coal-saving stove

The controlled quick startup coal stove of the coal burning of a kind of solid of the utility model and gas combustion dual mode dual-purpose belongs to energy technology.

In China, because domestic gas is under-supply, in a quite long period, most of people's in small and medium-sized cities and small towns life will be based on direct fire coal with fuel.Consult relevant patent documentation and technical data according to the designer, for coal furnace, though had development faster in recent years, two air intake honeycomb briquette stoves of introducing from Japan for example, to promote abundant burning, set up heat collector panel improving ignition temperature, but this stove still has a lot of shortcomings by the secondary oxygen supply: (one) speed of getting angry is slow, bank up a fire behind the several hrs, temperature reduces in the stove, adds new coal, and temperature is lower in the stove, needed just can get angry in 15～30 minutes, and influenced people's work and rest; (2) poor performance of banking up a fire, if the air admission hole envelope is tight excessively, fire is suffocated by regular meeting, and is big slightly if air admission hole stays, tends to make burning too fast again, make coal very fast burn burn down, do not reach the purpose of banking up a fire equally; (3) the stove fire size can not resemble arbitrarily control on demand the gas furnace, uses inconvenient.

From over 1986, a kind of jet-propelled coal furnace has appearred in China, has improved the speed of getting angry, but this stove is to provide pressure by water-head, controls tolerance with the control water yield, so pressure is little, weak effect, and the sensitivity of control is low, and the speed of getting angry is still fast inadequately.

Task of the present utility model is a kind of controlled quick startup coal furnace that designs at the shortcoming that above-mentioned coal furnace exists, it can start fast, the time of getting angry is only used 5～8 minutes, the performance of well banking up a fire is arranged, can bank up a fire continuously 24 hours, the big I of its firepower is controlled as required.

Task of the present utility model is finished by following manner, place a regenerative apparatus (9) to improve fire box temperature in combustion chamber (19) periphery, thereby improving it banks up a fire and combustibility, be provided with high pressure gas-controlled type auxiliary combustion equipment (13), in stove, spray into high-pressure steam generation chemical reaction, produce fuel gas, we just can utilize direct burning and two kinds of combustion systems of fuel gas buring of coal simultaneously like this.Burner hearth is passed in the combustion gas that produces, and burns at an upper portion thereof, has improved the ignition temperature and the burning velocity of upper furnace, because the jet effect of the high velocity air that sprays into has produced very strong blasting action, has quickened burning simultaneously, has therefore shortened the time of getting angry greatly.For the size of regulating firepower, can change air inflow by adjusting control valve door (7) on the one hand and realize, on the other hand, a controlled firestopping ring (11) is set on fire door top, with its size of regulating fire door, further realize control to the stove fire size.This stove and accessory almost can resemble and be convenient to use the liquefied gas furnace.

Bottom is described in further detail in conjunction with the accompanying drawings.

Figure one is the utility model generalized section.

One, high pressure gas-controlled type auxiliary combustion equipment (13), it is by little inflator (1), the little water tank of vapour-pressure type (2), vaporizer (4) is crossed hot cell (5), control valve (7) and jet pipe compositions such as (8).Vaporizer (4) places the periphery of combustion chamber (19) or regenerative apparatus (9), the little water tank of vapour-pressure type (2) can be arranged at upper of furnace body, also can be arranged at body of heater bottom or outside, be connected with vaporizer (4) by water pipe (3), cross the top that hot cell (5) places vaporizer (4), and be communicated with it, give the little water tank of vapour-pressure type (2) inflation pressurization with little inflator (1), water in the little water tank (2) enters vaporizer (4) along water pipe (3), steam after the gasification entered hot cell (5), superheated vapor enters wireway (6) by crossing hot cell (5), by control valve door (7), enter jet pipe (3), ejection enters in the burner hearth from spray orifice (14).

Two, regenerative apparatus (9) is made up of a double sandwich sleeve, is placed in the periphery of garden cartridge type combustion chamber (19), and high-temperature phase change heat accumulation material (10) is equipped with in interlayer inside, to guarantee the temperature of burner hearth during banking up a fire.

Three, controlled firestopping ring (11), its representative instance can be an a pair of slotting type firestopping ring (11), (figure two), it comprises that two profiles of tooth are equipped with tooth bar (16) to each plate inboard of plate (18) adjusting turn-knob (17) is housed on gear (20) gear (20) that extent of opening between the adjusting plate is housed between two tooth bars.(17) are turned round in turn control, make two tooth bars (16) relative motion, can make two profiles of tooth plate (18) be left or close up, and realizing opening or seal fire door, thereby control the size of stove fire.

Four, filling high-temperature resistant thermal insulating material around the body of heater, is insulation and the fire resistance that improves body of heater, and after banking up a fire, controlled firestopping ring (11) will revolve to put and close up state, covers a garden column type or a garden dish-type furnace crown (12) of being made by high-temperature resistant thermal insulating material above again.

Five, fire door (15) in order to air inlet, goes out ashes when opening, and banks up a fire with realization during sealing.

The utility model has fundamentally improved the deficiency of common coal stove, and therefore while dual-purpose solid combustion and two kinds of combustion systems of fuel gas buring have following characteristics:

1, thermal efficiency height, this stove and accessory both can be used for cooking, also can be used for warming, and the thermal efficiency can reach 80%.

2, the speed of getting angry is fast, and the general coal stove time of getting angry is 15～30 minutes, and this stove time of getting angry is 5～8 minutes.

3, the big I of firepower is regulated as required, can resemble convenient use the gas furnace.

4, the performance of banking up a fire is good, can bank up a fire continuously 24 hours, can use at once after opening.
