Description
Technical field
The invention belongs to the fuel gas caloric value determination apparatus technical field, especially relate to a kind of self-preheating burner that is used on the fuel gas caloric value determination apparatus.
Background technology
The burner tip of using on the tradition fuel gas caloric value determination apparatus is not sealed; Smoke discharging pipe is located at the positive top or the upper lateral part of combustion chamber, and flue gas can be taken away great amount of heat, makes fire box temperature on the low side; Be unfavorable for the burning of coal gas; Especially for low-heat value gas, require certain environment temperature, environment temperature is crossed when hanging down and can be stopped working; And combustion gas and combustion air that traditional caloric value instrument adopts generally do not carry out preheating; So concerning low-heat value gas, igniting at normal temperatures can be crossed low and flame-out usually because of environment temperature, also just adds electric furnace heating wire around burner and in the furnace wall and solve the low excessively way of this temperature; Though this kind method can promote environment temperature; But owing to relate to the problem in service life of electric furnace heating wire, need periodic replacement, can cause that maintenance process is loaded down with trivial details, maintenance cost is high; And this kind method manufacture craft is comparatively complicated, and cost of manufacture is high.
Summary of the invention
The object of the present invention is to provide a kind of self-preheating burner that is used on the fuel gas caloric value determination apparatus,, effectively guarantee the reasonable burning environment that fuel gas buring is required, and simplify production technology, reduce maintenance period and maintenance cost through making full use of the heat resource of self.
The objective of the invention is to realize through following technical proposals:
The self-preheating burner that is used on the fuel gas caloric value determination apparatus of the present invention; Comprise the combustion chamber; The exhaust gases passes that is connected of bottom, combustion chamber therewith; Be located at combustion air pipeline in this exhaust gases passes, gas pipeline and the burner that is connected of combustion air pipeline, gas pipeline therewith, it is characterized in that being provided with the sealing top board at described top of combustion chamber, the bottom of described exhaust gases passes is connected with a smoke discharging pipe.
Described exhaust gases passes bottom outer wall is provided with flanged joint, and the end of described smoke discharging pipe is provided with the adpting flange of band seal washer, and this adpting flange is fixedly connected with described flanged joint through securing member.
Operation principle of the present invention:
Gaseous mixture is lighted the back and is ejected in the combustion chamber from burner; Because the top closure of combustion chamber; The flue gas that burning back produces can't directly be discharged outside the burner, and because of smoke discharging pipe is positioned at the bottom of combustion chamber, flue gas can be after colliding the top, combustion chamber make a circulation in the exhaust gases passes below the flow direction because furnace pressure is a malleation; Owing to receive the percussion that flame makes progress in the middle of the combustion chamber; Therefore circuitous flue gas can flow downwards along the outer wall of combustion chamber, flows through the outer wall of burner, combustion air pipeline, is discharged to outside the burner through outer smoke exhaust pipe road again.In stove, travel back across the bottom of combustion chamber because this flue gas does not have directly discharge under the effect of malleation, therefore improved combustion chamber temperature, guaranteed the required environment temperature of burning, and make that fuel gas is abundant, completing combustion; Flue gas travels back across the bottom of combustion chamber, can flow through the outer wall of burner and combustion air pipeline, has played the effect of preheating; Because the flue gas here is very near from the combustion chamber, so temperature is very high, is equal to fire box temperature basically; Can the gas in burner and the air duct be carried out preheating, because gas pipeline is in the inboard of combustion air pipeline, therefore after the combustion air in the combustion air pipeline is by preheating; Combustion air is flowed through the outer wall of gas pipeline again can the preheating fuel gas, makes fuel gas and combustion air before mixing, a higher temperature arranged, and is easier to igniting; Because fuel gas does not contact before burner with combustion air, so does not have explosion danger after the preheating, the outer wall of while burner because flue gas is flowed through; Can carry out preheating to burner again, make to keep a higher temperature in the burner, be easy to gaseous mixture more and lighted; Under triple preheatings of flue gas, can effectively guarantee the ignition success rate of gaseous mixture, and continue, stablize, burn completely.
Advantage of the present invention:
1) the present invention has improved fire box temperature because the top, combustion chamber is closed, and has guaranteed the required environment temperature of burning, and is easy to fuel gas completing combustion more;
2), make that igniting is easier because smoke discharging pipe of the present invention is positioned at the bottom of burner, and the backflow of flue gas can be played the effect of preheating burner, combustion air pipeline and gas pipeline;
3) rational structure combination of the present invention, the existing heat resource of a utilization itself, production technology is simple, safeguards simply, does not produce maintenance cost, more convenient user's use.
Description of drawings

The specific embodimentFigure
Below in conjunction with the description of drawings specific embodiment of the present invention.
As shown in Figure 1: the self-preheating burner that is used on the fuel gas caloric value determination apparatus of the present invention; Comprise combustion chamber 4; The exhaust gases passes 5 that is connected of 4 bottoms, combustion chamber therewith is located at combustion air pipeline 1 in this exhaust gases passes 5, gas pipelines 2 and the burner 3 that is connected of combustion air pipeline 1, gas pipeline 2 therewith, it is characterized in that being provided with at 4 tops, described combustion chamber sealing top board 7; The flue gas that produces after 4 internal combustion of combustion chamber like this can't directly be discharged from the top; The bottom of described exhaust gases passes 5 is connected with a smoke discharging pipe 6, collide the sealing top board 7 on 4 tops, combustion chamber when flue gas after, receive the percussion that burner 3 flames make progress; Force flue gas can only make a circulation to flow downwards, and get in the exhaust gases passes 5.In the time of this flow of flue gas, promptly played effect to combustion-supporting airduct 1, gas pipeline 2 and burner 3 preheatings, insulation; Make fuel gas and combustion air before mixing, a higher temperature arranged, be easier to igniting; Also improved the temperature in the combustion chamber 4, guaranteed the required environment temperature of burning, and made that fuel gas is abundant, completing combustion.Flue gas after circulating is discharged through smoke discharging pipe.
Described exhaust gases passes 5 bottom outer walls are provided with flanged joint 5-1; The end of described smoke discharging pipe 6 is provided with the adpting flange 6-1 of band seal washer; This adpting flange is fixedly connected with described flanged joint 5-1 through securing member 6-2, is convenient to adopt the smoke discharging pipe of different size.
