Meanwhile the high-temperature flue gas waste heat for making the high-temperature flue gas after burning drain into flue 10, pass through outer refractory
Water circulation coil pipes 3 are by the gradual cyclic absorption of secondary flue gas waste heat institute on the perisporium of thermal insulation layer 4, and inlet water tank follows obtained hot water again
Ring, when circulating hot water reaches the setting temperature of cooling-water temperature sensor 18 in water tank 11, started with water water pump 17.Self-con-tained unit 7 is
Instruction with water water pump open after, will be stored in the delivery in water tank 11 to the total boiler in kitchen, be available for total kitchen with
Steam box moisturizing is supplied with the grade of this stove hot water tap 9 hot water.Each monomer stove is set to reach the remarkable effect of synergy again more than 10%.
When temperature sensor 18 reaches setting temperature in water tank 11, automatic controller 7 is that instruction water water pump 17 starts, by water
Delivery in case stores to the total boiler in kitchen is interior, meanwhile, water vapor linked valve delivery port 19 can be carried out to water tank 11 automatically
Moisturizing, reach water level balance or ball-cock assembly in water tank 11 and close.
Whole operation program process：Cold water inlet valve under the foreboard of stove framework 8 is connected with water, gas interstage valve 14,
After first opening cold water switch before water, gas interstage valve 14, water, gas and electricity threeway is realized；Water, the cold water of gas interstage valve are i.e. into water, gas
In interstage valve 14 below film layer, on the one hand push rod opens water, in gas interstage valve 14 simultaneously above film under hydraulic pressure effect
Burnt gas valve enters magnetic valve, and the cold water of water vapor linked valve delivery port 19 is formed into water tank and water circulation coil pipes entrance simultaneously to follow
Ring, and simultaneously it is electric started by the synchronic command of self-con-tained unit 7, kitchen range is entered general safety, stably, reliably by program
Operating mode is run.Water, gas interlocked valve 14, operation are first to open water valve, obtain hydraulic pressure effect, and inside automatically turns on gas valve entrance again
Magnetic valve waits instruction.
The cold valves handle that water on stove front panel, the leading portion of gas interstage valve 14 are first pinned with the right hand is operated first, towards counterclockwise
Direction is rotated to 90 ° of positions, that is, opens cold valves, and cold water quickly enters water, film layer lower end in gas interstage valve 14, on the one hand exists
Push rod opens water, the burnt gas valve in gas interstage valve 14 simultaneously above the lower film of hydraulic pressure effect, fuel gas source GAS1 is flowed into automatic control
In gas electromagnetic valve in device, while cold water flows into water tank all the way by film layer upper end, water, gas interstage valve 14b cold water
11 bottom, another way cold water flow to the lower end of water circulation coil pipes 3, and from bottom to top flow into the top of water tank 11, two-way cold water
Into after water tank 11, the water level of water tank 11 can be progressively set to be tended to be balanced under ball float effect.
After water, gas interstage valve 14 are opened, obtain power supply E1 electric, even if self-con-tained unit 7E2 is electricly synchronous, in 2~3 seconds

Left and right, self-con-tained unit 7 just export S1 signals to the igniting on more sides of standpipe combined efficient power-saving infrared burner 5 and fire in burner hearth
Flame detection pin S2 implements to carry out seedling ignition combustor pulse firing and flame ion detection, if seedling fire does not detect at the appointed time
To flame, self-con-tained unit 7 is that can cut off gas source rapidly, the meeting sound and light alarm prompting of indicator lamp 20 before stove on left panel, this
When self-con-tained unit will enter defence program, then it represents that operating personnel need to restart preparation again.If seedling fire lights success, automatic control
After magnetic valve can wait seedling fire flame stabilization in device 7, flame ion detection probe can quickly perform magnetic valve self-locking, that is, open certainly
Control seedling fire valve D1 in the gas electromagnetic valve in device 7 to open, then seedling fire combustion gas gas1 is sent into gas2 burner hearths by seedling fire tube road
In the seedling ignition combustor on more sides of standpipe combined efficient power-saving infrared burner 5.Main fire valve D2 simultaneously in gas electromagnetic valve is same
Step is opened, and combustion gas has been directly communicated to wait operating personnel to be grasped main fire with the right hand during main fiery operation valve 6, Sui on guidance panel
Make valve 6 and be counterclockwise rotated by 90 ° position, implement to run under fuel gas buring Full loads, now stove back upper right side
The power numeral of combustion gas, when the main fiery handle of operation valve 6 turns down clockwise, display can be shown on the screen of display 21
Power on 21 screens shows that number synchronously reduces.
After operating personnel open the main fiery progress of operation valve 6 normal operating of gas apparatus, more standpipe combination high-efficiency sections in burner hearth
Energy infrared burner 5 carries out various culinary art cookings and into certainly into safe and reliable, complete, stable fired state at once
Control the internal circulation system that programmed instruction cold water implements self-closing negative-pressure type preheating cold water from bottom to top.
When the hot water of interior circulation in burner hearth outer refractory thermal insulation layer 4 reaches the setting of cooling-water temperature sensor 18 in water tank 11
During temperature, self-con-tained unit 7 is to instruct the water water pump 17 i.e. automatic start for kitchen boiler, as shown in figures 1 and 3, for kitchen
The total boiler in room is opened with water water pump 17, will be stored, is available in the delivery in stove inner water tank 11 to the total boiler in kitchen
Total kitchen and steam box moisturizing are supplied with the grade of this stove hot water tap 9 hot water.Estimate each monomer stove；It just can reach synergy again
More than 10% remarkable effect, reach secondary fume waste heat recovery synergistic effect.
In a word, presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent be the foregoing is only
