Description

The cooking, boiling water, bathing and heating room multipurpose furnace

The utility model relates to a kind of burning coal that looses not only can cook a meal with brick kitchen range but also can boiling water without interruption and hot water, added the multipurpose stove that cold water is applicable to that dining rooms such as office, school, restaurant are used automatically.

Burn bituminous coal at present and use brick kitchen range, have reverse burning cooking range and secondary wind kitchen range etc. multiple by cooking a meal of environmental requirement smoke abatement and dust control.Reverse burning cooking range is to utilize machinery to deliver coal from the bottom up to reach in the bituminous coal volatile matter fully to burn to eliminate the effect of black smoke.The machinery of delivering coal divides fluid pressure type and cagem type, all exists inconvenient operation, the shortcoming that the fragile life-span is short; Secondary wind kitchen range coal is with common to pull out the wind kitchen range the same, when under fire grate, blasting a wind, in burner hearth, blast the effect that secondary wind reaches the elimination black smoke with manually coal being added in above the fire grate uniformly, its shortcoming is that the cast iron burner hearth of supplying with secondary wind very easily burns out because of directly contacting flame, causes the chimney over-emitting black exhaust.More than the common drawback of two kinds of smoke elimination kitchen ranges can not normally use will emit when being coal the black smoke of a period of time to have a power failure the time, the thermal efficiency is not high.

The purpose of this utility model is to design does not a kind ofly have electricity can use yet, and flue dust reaches environmental requirement, long service life, and the burning bituminous coal brick kitchen range that the thermal efficiency is high, and can make boiling water without interruption, the multipurpose furnace that the boiler of hot water uses.

Fig. 1 is a body of heater contour structures schematic diagram.

Fig. 2 is the body of heater profile.

The utility model is achieved in that coal is passed through upper furnace door (17) adds upper furnace (19), when Upper furnace door (17) is turned over turnover panel (28) simultaneously to the right air from upper furnace door (17) when opening enter and supply with combustion Burn required oxygen, enter lower furnace (15) and through flue (14) through the hot flue gas that produces behind the coal combustion Enter secondary furnace (27) and enter atmosphere from chimney (2). Partly the upper unburnt coal of upper fire-grating (12) falls The required oxygen that burns away on the lower fire grating (13) has ash discharging hole to enter. Reach for the double-layer grate combustion mechanism this moment To the purpose of eliminating black smoke, hot flue gas runs through the water tank sufficient heat exchange from burner hearth and enters atmosphere by chimney. When upper furnace door (17) is closed, simultaneously turnover panel (28) is turned over the left side, open the rear air of lower furnace door (16) from lower Fire door enters, and up supplies coal combustion. The flame that burning produces directly heats iron pan (9), hot flue gas from Flue (20) enters chimney (2) through secondary furnace (27) and enters atmosphere and pull out at this moment the wind brick kitchen range and use. From secondary Air port (18) enters the Secondary Air of secondary furnace (27) and hot flue gas is fully mixed that unburnt coal volatile matter is got Take full advantage of with the heat energy that burns away, guarantee not over-emitting black exhaust of chimney. Adjustment doors (1) is used for controlling pulls out wind-force; Automatic watering mechanism (24) adds water after the water level of boiler (23) is lower than lower limit, after water level is higher than the upper limit Cut off running water (25); When the water level of boiled water tank (22) drops to a certain degree, the water footpath in the boiler (23) Check valve (26) flows into boiled water tank (33), when the water level of boiled water tank (33) is higher than the water level of boiler (23), Boiling water flows into boiler through check valve (4) water is heated; Steam pipe (3) is with the steam in the boiled water tank (22) Inject boiler (23) to the water heating, and make boiled water tank (23) be in the operating on low voltage state. So just consist of Combustion process and the water cycle process of this stove.

(5) are furnace shells as shown in the figure; (6) heat-insulation layer; (7) boiling water halter; (8) decorative panel; (9) iron pan; (10) range panel; (11) hand-hole is used for maintenance; (19) upper furnace is built into so that be incubated with refractory brick; (22), (23) hot water joint, be used for the heating of external hot water circuit and have a bath; (31) hot water halter; (32) cap relief valve.

In sum: the utility model has adopted compositions such as double-layer grate combustion chamber, secondary wind secondary furnace, boiled water tank and boiler, iron pan, flue, chimney, turnover panel.Cooking a meal when using with brick kitchen range: fire down instead burns through secondary wind secondary furnace further oxidation again and makes the abundant after-flame of volatile matter in the coal during coal.Just burning when normal combustion, residual flammable composition is at secondary wind secondary furnace exhaustive oxidation after-flame.Situation when doing to equal above-mentioned coal when boiler uses.Therefore guarantee that fuel is fully burned, chimney is over-emitting black exhaust not, have province's coal, safety, automatic loading water, can boiling water without interruption and the advantage of hot water have cook a meal, tea, bath, warm multiple use.
