Description

Waste heat energy saving gas stove

The utility model relates to a kind of public coal gas cooking stove that adopts atmospheric burner.

The public coal gas cooking stove of atmospheric burner of domestic production at present is the smoke directly ventilating formula.It has one or more heating furnaces, and each heating furnace is the individual layer furnace wall, and the bottom is a burner, and top is a pot frame.Ember and flue gas are directly discharged from the space between frying pan limit and the pot frame.Therefore, the cook time often suffers the smoked hardship of fiery flue-cured tobacco in operation, and simultaneously, frying pan that the cook is used or spoon are surrounded by naked light, cause hot-spot, when fry good dish take the dish out of the pot, spoonful the time, often cause coking or color blackening, influenced cooking quality.In addition, because naked light is a lot of with the touch opportunity of pot, the interior oil of spoon, and easily cause the phenomenon of catching fire in the pot.It is pointed out that the structure of this cooking stove, determined ember and flue gas to discharge from the space between frying pan and the pot frame, like this, the major part of the heat that is discharged during gas-fired is also discharged thereupon, so thermal waste is big.

The purpose of this utility model provides a kind of cooking stove with closed annular flue burner hearth, to improve cook's operating environment, improves the cooking quality of vegetable, and improves the public coal gas cooking stove of atmospheric burning type UTILIZATION OF VESIDUAL HEAT IN of heat energy utilization rate.

For this reason, the structure taked of the utility model is like this: be made up of two identical in structure heating furnaces (1) (2), a UTILIZATION OF VESIDUAL HEAT IN chamber (3), shell and exit flue (4).Wherein the furnace wall of each heating furnace (1) (2) is to be burner hearth in the inside and outside double furnace wall, and being positioned at lower furnace portion is atmospheric burner (9).This inside and outside double furnace wall is to enclose circle with the iron plate of thick 1～3mm to be welded, and forming distance therebetween is the closed annular flue (4) (5) of 40～60mm.Closed annular flue (4) (5) skin, promptly the double furnace wall outer surface adheres to heat-insulation layer (6), to reach the heat-insulation and heat-preservation purpose.Closed annular flue (4) (5) internal layer, promptly double furnace wall inner surface cover system refractory cement layer (7) plays heat-blocking action, makes burner hearth can not bake overheated the distortion because of being subjected to fire.On the furnace wall, vertical refractory cement layer (7) surface has 4～14 rectangle exhaust openings (8) along circumference.The locular wall of above-mentioned UTILIZATION OF VESIDUAL HEAT IN chamber (3) is an individual layer, is to surround cylindric being welded with thick 1～3mm iron plate.There is a circular open its upper end.The one cylindric slaughterhouse (10) of packing into from above-mentioned circular open is arranged in the UTILIZATION OF VESIDUAL HEAT IN chamber (3), constitute flue (11) between the locular wall of this slaughterhouse (10) and UTILIZATION OF VESIDUAL HEAT IN chamber (3).UTILIZATION OF VESIDUAL HEAT IN chamber (3) is communicated with closed annular flue (4) (5) in above-mentioned two heating furnaces (1) (2) respectively by two connection flues (12) (13).In addition, UTILIZATION OF VESIDUAL HEAT IN chamber (3) away from its connection be connected flue (12) (13) opposite side, have an exhaust opening, the flue (11) in the UTILIZATION OF VESIDUAL HEAT IN device (3) is communicated with exit flue (14) by this exhaust opening.In addition, its outer surface also adheres to heat-insulation layer (23).

The burner (9) of heating furnace (1) (2) bottom makes gas-fired, and the heat that gas-fired produced is absorbed by frying pan, waste heat then enters closed annular flue (4) (5) by exhaust opening on the furnace wall (8), enter UTILIZATION OF VESIDUAL HEAT IN chamber (3) by connecting flue (12) (13) again, be used to heat slaughterhouse (10).Thereby waste heat is fully utilized.Secondary waste heat and cigarette then come out from the flue (11) that constitutes between slaughterhouse (10) and UTILIZATION OF VESIDUAL HEAT IN chamber (8) wall, by exhaust opening, after exit flue (14) discharge.

The utility model is provided with the space owing to adopt closed annular flue (4) (5) between frying pan and pot frame, and ember and cigarette can not run into the kitchen, makes frying pan obtain evenly, heat fully.In addition, waste heat and flue gas by closed ring flue (4) (5), be connected flue (12) (13) after, enter UTILIZATION OF VESIDUAL HEAT IN chamber (3), make the middle soup of slaughterhouse (10) obtain heating, thereby waste heat is fully used, has reduced exhaust gas temperature, heat utilization efficiency improves.Closed annular flue (4) (5) has guaranteed that kitchen environment is not contaminated, has improved operating condition, and it is roasting to make the cook avoid smoke fire.

Fig. 1 is the utility model profile schematic diagram.

Shell is made up of with base plate side plate (15), front panel (16), rear board, range panel (17).Being positioned at range panel (17) back end edge, is backboard (18) perpendicular to this range panel (17).

Ever-burning flame switch (19), pulse auto lighting switch (20), burner switch (21) also are housed on the plate (16) in front.

22 is the igniter battery case.
