Observe door (2) and be used for observing combustion case, exhaust outlet (9) can connect blast pipe, allow steam discharging, making the pressure in the furnace tube (16) is normal pressure, upper perforated plate (10) fixedly tubulation (13) upper end also is the demarcation strip of boiling water body of heater (6) and smoke-box (8), pair discharge orifice (28) is arranged on the demixing plate (12), boiling water exports (11) after pipeline flows out by boiling water, hot water is through entering the boiling water body of heater to discharge orifice, the existence of demixing plate (12) has reduced boiling water and has been back in the hot water body of heater (18) and goes, can guarantee the supply of boiling water, tubulation (13) is as quirk, and the lower end is fixing by lower perforated plate (17), be communicated with burner hearth (19), the upper end is logical with smoke-box (8) limit, advances fire hole (20) and sprays into the inlet of burner hearth (19) for fuel, and insulation layer (15) adopts fiber heat preservation material, cooling water inlet (23) taps into waterpipe, hot water outlet (27), boiling water outlet (11) picks out waterpipe, and thermometer hole (26) seals after inserting thermal detector.The utility model is fuel used to be oil or liquefied gas, fuel sprays into burner hearth (19) internal combustion by burner through advancing fire hole (20), and first heats cold water ring, water in the curved water pipe, continue completing combustion through tubulation (13) then, water in the furnace tube (16) is heated, hot water upwards flows, and be subjected to the lasting heating of tubulation (13), near the demixing plate (12) time, water temperature is near boiling point, export (11) to boiling water and reach boiling point fully, the steam of the water generates of boiling is discharged by exhaust outlet (9), guarantees that the pressure in the boiling water body of heater (6) is normal pressure, after flue gas arrives smoke-box, the oblique horizontal water tube of transversal flow further carries out being discharged by chimney after the heat exchange.The hot water that boiling water, hot water two purpose stove produce is exported from hot water outlet (27).Boiling water is located output by boiling water outlet (11).Therefore can supply boiling water and hot water simultaneously.

The utility model has increased cold water ring and curved water pipe in burner hearth (19), so just increased heating surface, has reduced bottom temperature simultaneously, has reduced heat and has scattered and disappeared; In smoke-box, increased oblique horizontal water tube, increased heating surface, reduced exhaust gas temperature, the utility model has been done on the basis of former boiling water, water heater after these two improvement, the thermal efficiency of dual-purpose stove brings up to 91% by original 85%, black furnace provides the time of boiling water to shorten to 12 minutes by original 14 minutes after starting, and has reached efficient, purpose of energy saving.In addition.Because the utility model material therefor is generally the high-quality stainless steel, is easy to remove incrustation scale in the body of heater, thereby the problem that general water-tube boiler lowers efficiency because of pipe scaling is difficult to remove occurs and can in the utility model, not occur with medicine.

Use the utility model can be easy to the automatic control of commence operation operation, alleviate labor intensity of operating personnel.Fig. 4 and Fig. 5 have provided the embodiment that the utility model automatic water-supply, oil supply system figure and automatically controlled circuit diagram are installed at the flat-roofed house roof.Pipe temperature relay (30, be when water temperature is lower than a certain temperature (as 60 ℃) in return pipe 1WDJ), connect back water pump (33,2SD) circuit, back water pump (33,2SD) be used for that pipeline is lower than 60 ℃ water pump and return dual-purpose stove (38), check valve (34) stops the interior water of dual-purpose stove and the side of liquid level water tank (42) to flow back to water pump (33), hot water temperature's relay (40,2WDJ) be used to control the igniting of burner (L) and stop working, the feedwater height of liquid level water tank (42) control dual-purpose stove (38), boiler (43) is stored boiling water, boiling water liquid level relay (44,3YJ) be used to control the igniting of burner (41) and stop working, burner (41, L) by oil pump, nozzle, air blast, automatic ignitor is formed, oil jetting combustion in burner hearth (19), the required oil level of liquid level fuel tank (46) control burner (41).Automatically the control course of work is: power turn-on switch 1HK, water pump 1SD electric motor starting, water pump supplies water to liquid level water tank (42), liquid level water tank (42) again to the dual-purpose stove automatic water-supply with it simultaneously, fluid position relay (45,2YJ) connect auxiliary reclay YC, oil pump (48, YD) start, oil pump is to liquid level fuel tank fuel feeding, and the liquid level fuel tank is again from trend burner (41, L) fuel feeding, change-over switch 3HK closes, temperature relay 2WDJ connects auxiliary reclay LC, and burner L starts, flame in burner hearth, when water temperature in the dual-purpose stove is raised to temperature relay 2WDJ setting temperature, the 2WDJ action, the LC dead electricity, burner L is out of service.Be lower than when setting up liquid level when the liquid level in the boiled water tank (43) again, liquid level relay (44,3YJ) is connected auxiliary reclay LC, and burner L starts, flame in burner hearth, when the liquid level in the boiled water tank reaches the transfer liquid level, the 3YJ action, the LC dead electricity, burner L is out of service.When water temperature in the return pipe is reduced to when setting up temperature, pipe temperature relay 1WDJ connects 2SC, and back water pump (33,2SD) electric motor starting returns the water pump in the pipeline to dual-purpose stove and reheats, and when do not need the back water pump startup night, can disconnect change-over switch 2HK.When water pump, when oil pump burning needs are manual, can be by the button that starts or stops separately.Pump motor, Oil pump electrical machinery have all been installed indicator lamp in the control circuit of burner, can monitor the operation of dual-purpose lamp and whole unit according to indicator lamp.

The utility model is rational in infrastructure, volume is little, in light weight, take up an area of and lack, a stove is dual-purpose can supply boiling water and hot water simultaneously, and usable oils or liquefied gas are made fuel, free from environmental pollution, and easily realize automation mechanized operation operation, efficient, energy-conservation, be well suited for hotel, hotel, residential area, office building etc. and be installed in roof and supply boiling water, hot water automatically to the user, as the heating in winter and summer the lithium bromide central air conditioning thermal source.
