The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1, heat storage type combustion stove disclosed in the utility model is to be fuel with fuel gas or flammable liquid, is applied to the smelting of non-ferrous metals such as tin, lead, aluminium, copper, the firing equipment in the processing technology.In the present embodiment, heat-accumulating burner and by-pass valve control are two respectively, are oppositely arranged on two exits of circulation air path, and for stability and the accuracy of controlling, by-pass valve control can also be connected with the PLC controller by circuit respectively, realize Digital Control.
This heat storage type combustion stove comprises and smelts pot 1 that the outer cover of smelting pot 1 is equipped with body of heater 2, smelts between pot 1 and the body of heater 2 to be provided with circulation air path 3.The exit of circulation air path 3 is respectively arranged with heat-accumulating burner, comprise a heat-accumulating burner 17 and No. two heat-accumulating burners 4, also be respectively arranged with connected burning torch on the heat-accumulating burner, i.e. a burning torch 16 and No. two burning torches 5, each heat-accumulating burner are connected with separately by-pass valve control respectively.No. one heat-accumulating burner 17 all is connected with reversal valve 7 with No. two heat-accumulating burners 4, and reversal valve 7 is connected with air-introduced machine 18 with air blast 12.By-pass valve control all is provided with on the fuel tube 11 that is the heat-accumulating burner connection, and fuel tube 11 is divided into two branch roads: one is passed through the igniting motor-driven valve and directly is connected with heat-accumulating burner; A fuel control valve 10 is set on another branch road, is connected with heat-accumulating burner by after the fuel cutoff valve respectively by the pipeline after this fuel control valve 10.
By-pass valve control comprises igniting motor-driven valve and fuel cutoff valve, is divided into igniting motor-driven valve 15, fuel cutoff valve 13, No. two igniting motor-driven valves 6, No. two fuel cutoff valves 8 according to the difference of the heat-accumulating burner that is connected.
The pipeline that reversal valve 7 is connected with air-introduced machine 18 is provided with exhaust gas temperature transmitter 14; The pipeline that reversal valve 7 is connected with air blast 12 is provided with volume damper 9.
Operation principle of the present utility model is:
Metal that will melting places to be smelted in the pot 1, smelt pot 1 and be installed in body of heater 2 inside, a circulation air path 3 is set between the two, two heat-accumulating burners 4,17 are installed in the exit of body of heater 2 fronts, circulation air path 3, are formed fuel combustion control system and are realized the accumulation of heat commutation function by fuel cutoff valve 8,13, reversal valve 7, volume damper 9, fuel control valve 10, exhaust gas temperature transmitter 14, igniting motor-driven valve 6 and 15, burning torch 5 and 16.An igniting motor-driven valve 15 and a burning torch 16 are used for lighting heat-accumulating burner 17 No. one, ignite after this burner master flame, No. one fuel cutoff valve 13 is in opening, equally, No. two igniting motor-driven valves 6 and No. two burning torches 5 are used for lighting heat-accumulating burner 4 No. two, ignite after this burner master flame, No. two fuel cutoff valve 8 is in opening, fuel control valve 10 is regulated size according to the height of hot blast temperature, volume damper 9 and the fuel control valve 10 proportional aperture sizes of regulating, make fuel and air before entering body of heater inside, mix in heat-accumulating burner earlier, and then enter in the body of heater, this just makes fuel and air fully mix, improve combustion rate, energy savings.
This heat storage type combustion stove is in operation when heat-accumulating burner 17 burnings, and No. two heat-accumulating burner 4 is in smoke evacuation accumulation of heat state, and this moment, reversal valve 7 made a heat-accumulating burner 17 be in the air blast state, and No. two heat-accumulating burner 4 is in the air inducing state.Because the obvious heat of smoke when No. two heat-accumulating burner 4 has been saved heat-accumulating burner 17 operations, thereby can make exhaust gas temperature be reduced to the tolerance limit stage, simultaneously, when this burner transfers fired state to, air is converted to the air sensible heat by heat-accumulating burner with the heat of saving, be used to the air distribution that burns, improve the temperature of air distribution, reduced smoke evacuation thereby saved fuel.Otherwise, when exhaust gas temperature transmitter 14 reaches setting commutation temperature, reversal valve 7 automatic reverses, at this moment No. two heat-accumulating burners 4 are in fired state, No. one heat-accumulating burner 17 is in smoke evacuation accumulation of heat state, this moment, reversal valve 7 made No. two heat-accumulating burners 4 be in the air blast state, and No. one heat-accumulating burner 17 is in the air inducing state.Obvious heat of smoke during 4 operations of No. two heat-accumulating burners of a same heat-accumulating burner 17 savings is applied to heat-accumulating burner 17 again during fired state by medium air, carries out reversing combustion so back and forth.Owing to adopted heat storage technology to make this combustion furnace reach the dual purpose that the energy-conservation and limit of the limit reduces the NOx discharge capacity.Storage heater alternate combustion and smoke evacuation in the heat-accumulating burner of combustion furnace body of heater both sides, high velocity air make furnace gas produce the very strong effect of mixing.The major flow of gas stream in the stove to be from an effluent to opposite side, and change direction constantly, thus expanded the flame combustion zone, the border of flame almost expands to the border of burner hearth, makes in the stove temperature even.Prolonged the service life of heating furnace.
