Description
Technical field
The utility model relates to a kind of dining room of supplying large and medium-sized dining room combustion gas large stove, can produce in cooking especially that steam carries out steamed rice, washes water open, many function, energy-savings kitchen range of heat supply water.In particular, he is a kind of fire-tube type high efficiency burnt gas steam engine kitchen range
Background technology
Present combustion gas large stove generally has only the function of cooking, carries out cooking at them, and flue gas just is not utilized and directly enters in the atmosphere when boiling water, so general heat energy utilization rate is low, and the exhaust gas temperature height, the general thermal efficiency has only 20%--30%.And in some large and medium-sized dining rooms, school lunch service should cooking, cook bear again boil water, towards gruel etc., so common combustion gas large stove just can not satisfy their demand, they just must drive two or three stoves simultaneously and carry out different work simultaneously, could satisfy their demand, so just make the dining room expend very big human and material resources and financial resources.
The utility model content
Technical problem to be solved in the utility model provides a kind of heat energy utilization rate height, multi-use, fire-tube type high efficiency burnt gas steam engine kitchen range that cost of investment is low.
In order to solve the problems of the technologies described above, the fire-tube type high efficiency burnt gas steam engine kitchen range that the utility model provides, comprise stove, burner hearth, burner and flue, in the burner hearth of described stove, be provided with the tubular steam engine, be formed with smoke-box between the inwall of the outer wall of described tubular steam engine and the heat-insulation layer of described stove, described smoke-box is connected with described flue, in described tubular steam engine, be provided with the smoke-box interlayer, described smoke-box interlayer upper end is connected with the many fire tubes that are communicated with burner hearth, the sidewall of described smoke-box interlayer is connected with the many smoke exhaust pipes that are communicated with described smoke-box, the bottom of described tubular steam engine is provided with the blowdown joint, and described tubular steam engine is provided with inlet union and steam (vapor) outlet.
Heating surface covers the outer wall of whole described tubular steam engine in the described smoke-box.
Many described smoke exhaust pipes radially evenly arrange along described tubular steam engine circumference, and many described fire tubes axially evenly arrange along described tubular steam engine circumference.
The inlet union of described tubular steam engine is connected with the float chamber, is provided with ball-cock assembly in the described float chamber.
The water capacity of the peak level of described tubular steam engine is less than 30 liters.
The inboard of described flue interlayer and described tubular steam engine, the outside and top all have at interval and at interval all be full of water layer.
Adopt the fire-tube type high efficiency burnt gas steam engine kitchen range of technique scheme, adopt the burner of the automatic IGNITION CONTROL of efficient energy-saving, burner is fixed on below the steam engine, allow fuel gas in the burner hearth internal combustion, the thermal-flame that produces directly washes away frying pan and carries out cooking, and radiation tubular steam engine inwall.The flame that washes away is run into the bottom of a pan and is returned down and enter fire tube, and flue gas enters the flue interlayer behind the fire tube absorption portion heat, enters smoke-box by smoke exhaust pipe then, and the heat in the flue gas is absorbed in a large number by steam engine.By chimney flue gas is entered air at last.The utility model makes flue gas through repeatedly streaming by utilizing the high-temperature flue gas after the cooking, fully absorbs the heat energy in the flue gas, makes full combustion of fuel, and heat fully absorbs, and the thermal efficiency is significantly improved, and reaches energy-conserving and environment-protective.
The utility model adopts the efficient heat-collecting fire tube, and through repeatedly streaming.Make fire tube stream formula gas steam engine kitchen range in cooking, fully absorb waste heat in this kitchen range and the flue gas by the efficient heat-collecting pipe, make steam engine produce minute-pressure steam, utilize its steam to carry out steamed rice, wash water open, towards gruel etc.Make fire tube stream formula gas steam engine kitchen range when cooking is finished like this, meal is also cooked, can also be provided part life boiling water.Make the thermal efficiency bring up to 70%--80% from the 20%--30% of traditional gas-cooker, take full advantage of its heat energy, reach multi-use, reduce the waste of cost of investment and thermal source.Because the water capacity of its peak level of steam engine does not belong to boilers and pressure vessel scope of inspection (the 2nd of " steam boiler safety and technical supervision rules " chapter 1 general provisions, these rules are not suitable for capacity less than fixed pressure steam boiler and the atomic energy boiler of 30L) less than 30 liters.Its steam engine air chamber is equipped with safety valve, and on steam engine output jet chimney any valve is not installed, guarantees that steam engine carries out work under the minute-pressure state.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, stove 1 is provided with burner hearth 16, burner 3, pipeline circuit control 8, cooker 17 and flue 15, in burner hearth 16, be provided with tubular steam engine 2, the upper end of tubular steam engine 2 is vaporium 12, be formed with smoke-box 6 between the inwall of the heat-insulation layer 7 of the outer wall of tubular steam engine 2 and stove 1, heating surface covers the outer wall of whole tubular steam engine 2 in the smoke-box 6, smoke-box 6 is connected with flue 15, in tubular steam engine 2, be provided with smoke-box interlayer 10, the inboard of flue interlayer 10 and tubular steam engine 2, the outside and top all have at interval and the interval in all be full of water layer, smoke-box interlayer 10 upper ends are connected with the many fire tubes 9 that are communicated with burner hearth 16, many fire tubes 9 axially evenly arrange along tubular steam engine 2 circumference, the sidewall of smoke-box interlayer 10 is connected with the many smoke exhaust pipes 11 that are communicated with smoke-box 6, many smoke exhaust pipes 11 radially evenly arrange along described tubular steam engine 2 circumference, the bottom of tubular steam engine 2 is provided with blowdown joint 13, tubular steam engine 2 is provided with inlet union 14 and steam (vapor) outlet, the inlet union 14 of tubular steam engine 2 is connected with float chamber 4, be provided with ball-cock assembly 5 in the float chamber 4, the water capacity of the peak level of tubular steam engine 2 is less than 30 liters, the water of certain altitude is equipped with in tubular steam engine 2 the insides, water is entering 2 li in tubular steam engine by float chamber 4 earlier, vaporium 12 sides have steam (vapor) outlet, steam (vapor) outlet is not installed any valve, directly connects kitchen tools such as steam-cooking cabinet.
Because the water capacity of the peak level of tubular steam engine 2 does not belong to boilers and pressure vessel scope of inspection (the 2nd of " steam boiler safety and technical supervision rules " chapter 1 general provisions, these rules are not suitable for capacity less than fixed pressure steam boiler and the atomic energy boiler of 30L) less than 30 liters.Its vaporium 12 is equipped with safety valve, and on steam engine output jet chimney any valve is not installed, guarantees that steam engine carries out work under the minute-pressure state.
