Abstract
The utility model relates to the heating furnace technology by using gas. The utility model has the main structure that an air box is arranged behind the sealed furnace body; an air changing device is connected with the upper part thereof. The upper part in the furnace body is provided with a baffle board; a burner is arranged at the lower part of the furnace body and is connected with an ejector; the ejector is connected with a valve and the valve is connected with a starting flame tongue and a thermocouple assembly. The air changing device of the utility model is composed of two concentric pipe sleeves of different radius by stacking together; the front end thereof is provided with a guard net and a device for preventing air from reversely flowing. The utility model has the advantages of safety and reliability and has the pretty yellow flame for watching; the thermal efficiency reaches the level above 85 percent.
Description
The utility model relates to the warming stove technology of using combustion gas.
The heater of existing use combustion gas, except because of the gas leakage security performance not too reliable, its thermal efficiency is not very high, is not really good-looking blue flame at the flame of European gas-operated thermal bath facility, its thermal efficiency 82%.In the U.S., gas-operated thermal bath facility has the yellow flame of a beauty, resembles very much the flame of the firewood of burning, and is very good-looking, but its thermal efficiency is less than 50%.
The purpose of this utility model is, a kind of all types combustion gas that is applicable to is provided, and do not have exhaust gas leakage, and combustion flame is yellow, and the thermal efficiency is higher than 85% the combustion gas stove that has air interchanger.
For achieving the above object, the technical solution of the utility model is; At the rear of airtight body of heater one watertight aircase is housed, its top connects air interchanger; Deflection plate is housed above in body of heater; Burner is housed below body of heater, and this burner connects injector, and injector connects valve, and valve connects and starts the tongues of fire and thermocouple sub-assembly.
Air interchanger by two with one heart but the pipe of different radii be nested in and form together, its front end has protection network and preventing air reverse flow device.
The shape of passing through opening of the air intlet of burner of the present utility model and combustion gas makes it the gaseous mixture of a desirable air and combustion gas so that obtain beautiful yellow flame, and lower wind door can make this mist reach optimal state.Air interchanger makes the utility model be different from traditional flue, and its extracting air is not in its residing room, but the outer fresh air of suction chamber, smog that produces during simultaneously with fuel gas buring and waste gas are discharged.The burnt gas switch valve connects thermocouple in addition, and when starting torch extinguished, valve promptly cut off air feed; Valve jointing temp sensor can keep temperature requiredly, and the utility model is not only safe and reliable for this reason, and the thermal efficiency is higher than 85%, is the desirable combustion gas warming furnace of warming.
Below in conjunction with accompanying drawing the utility model is elaborated:
Accompanying drawing 1 is a stereogram of the present utility model;
Accompanying drawing 2 is A-A cutaway views of the present utility model;
Accompanying drawing 3 is B-B cutaway views of the present utility model;
Accompanying drawing 4 is cutaway views of the utility model air interchanger;
Accompanying drawing 5 is the utility model 10KW burner and valve connection layout;
Accompanying drawing 6 is the utility model 8KW burner and valve connection layout.
Structure of the present utility model is shown in accompanying drawing 1,2,3,5,6, reaching cast iron plate 3 and base plate 13 by furnace sidewall 7 and 5, and the front is by to the doorstep 15 and the heating stove formed of lower wind door 19, and there is a watertight aircase 18 at its rear, is connected to air interchanger above watertight aircase 18; In the utility model bottom valve 14 is housed, by pipeline 20 city's net combustion gas is connected to valve 14, by pipeline 21 valve 14 is connected with thermocouple sub-assembly 9 with starting torch, pipeline 22 links to each other valve 14 with burner 17; Nozzle support 11, injector 12 and burner 17 are housed above valve 14; Nozzle reinforced 10 is connected to burner 17 places; Above burner 17 starting torch and thermocouple sub-assembly 9; In the utility model upper back, with watertight aircase 18 joints, deflection plate support 6 is housed, to fix one on this support and be skewed deflection plate 8, the top of deflection plate 8 is lower wind door 19 below Qianmen 15 against loam cake 4, and windowpane 16 is housed on door 15.
Air interchanger structure of the present utility model is as shown in Figure 4: overlapping outside air intake duct 2 in the outside of inner air intake duct 1, two air intake duct concentrics, different radii, the radius of outside air intake duct 2 are greater than the radius of inner air intake duct 1, and protection network and preventing air reverse flow device are equipped with in its termination.
During use, combustion gas arrives valves 14 from gas grid by pipeline 20, and valve 14 is with hand switch, and adjustable solar term flow is to burner 17 with start the tongues of fire 9, and when starting torch 9 extinguished, thermocouple 9 by-pass valve controls 14 cut off the air feed of heating stove.When combustion gas when piping 22 arrives injectors 12, in (region D) lining, burning has primary air there, arrives after the burner 17 (area E), mist expanded before going out from opening.Burning is above burner (regional F) just in time, and the secondary air that replenishes that brings with external straw 2 carries out together.Smog then flows along deflection plate 8 (regional G) in the stove, process laterally then, so that return to the back (H zone) of deflection plate, smog and waste gas can be discharged to inside air intake duct 1 (area I) lining of air interchanger by the flue interface there.
Air interchanger of the present utility model (seeing accompanying drawing 4) is made up of the pipe of two concentric different radiis, and inner air intake duct 1 (area I) can be got rid of the smog waste gas of heater inside; Outside air intake duct 2 (regional A) can be drawn the fresh air next from the outside.The end of air interchanger should be in the horizontal direction of outside, house, and (K zone) just can install air interchanger as long as have the hole of outside air intake duct 2 diameters in wall.
Claims (2)
1. a combustion gas stove that has air interchanger is made up of body of heater, pipeline, valve, burner, it is characterized in that, at the rear of airtight body of heater one watertight aircase is housed, and its top connects air interchanger; Deflection plate is housed above in body of heater; Burner is housed below body of heater, and this burner connects injector, and injector connects valve, and valve connects starting torch and thermocouple sub-assembly.
2. stove as claimed in claim 1 is characterized in that, described air interchanger by two with one heart but the pipe of different radii be nested in and form together, there are protection network and preventing air reverse flow device in its termination.
