Abstract
The utility model discloses a kind of gas-solid double fuel boiler, comprise feed hopper, chain or reciprocal grate, burner hearth, boiler convection bank, upper strata rear arch and lower floor's rear arch, be gas combustion chamber between upper and lower layer rear arch, gas combustion chamber front end communicates with burner hearth, rear end is provided with gas burner system, the gas flame of combustor ejection moves from back to front, enters boiler furnace from gas combustion chamber; Chain or reciprocal grate are positioned at the below of lower floor's rear arch, and solid fuel, from the feed hopper input being positioned at boiler front portion, drives through chain or reciprocal grate, moves from front to back.Boiler of the present utility model adopts chain or reciprocal grate technology, and existing individual layer rear arch is changed into double-deck rear arch, like this between double-deck rear arch, just define a space as gas combustion chamber, thus achieve not only can burning solid, but also can the object of combustion gas.
Description
Technical field
The utility model relates to a kind of boiler, especially a kind of not only can burning solid, but also can the boiler of combustion gas.
Background technology
At present, domestic city is all faced with the problem how traditional industry boiler is transformed, and is trend of the times with gas for coal, but, on a large scale coal-burning boiler is changed into gas fired-boiler and there are again the problems such as source of the gas is not enough.
Gas-solid double fuel boiler can adapt to the demand of this situation.First, when not possessing combustion gas condition, this boiler can solid be fuel, waits when in the future possessing gas supply condition, and this boiler can direct gas fired.Secondly, if two kinds of fuel have, but fuel supply is unstable, with season, changes with fuel reserve situation, and only there is restriction in season by living beings not, only with gas, this boiler also can solve this and make us awkward problem.
But existing gas-solid double fuel boiler, pulverized-coal fired boiler basis grows up, its combustion system is room combustion, and solid fuel must first be clayed into power, and just can spray into boiler combustion, and the investment of milling equipment is huge, has even exceeded the price of boiler main frame.And invest the grate firing boilers such as the wide chain of little application, reciprocal grate due to the restriction by fire grate and individual layer chimney arch, be only limited to solid-fuelled burning always, before this patent, not yet occur gas-solid double fuel grate firing boiler technology.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of not only can burning solid, but also can the chain of combustion gas or reciprocating-grate boiler.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of gas-solid double fuel boiler, comprise feed hopper, chain or reciprocal grate, burner hearth, boiler convection bank, upper strata rear arch and lower floor's rear arch, be gas combustion chamber between upper and lower layer rear arch, gas combustion chamber front end communicates with burner hearth, rear end is provided with gas burner system, and the gas flame of combustor ejection moves from back to front, enters boiler furnace from gas combustion chamber; Chain or reciprocal grate are positioned at the below of lower floor's rear arch, and solid fuel, from the feed hopper input being positioned at boiler front portion, drives through chain or reciprocal grate, moves from front to back.
Boiler of the present utility model adopts chain or reciprocal grate technology, and existing individual layer rear arch is changed into double-deck rear arch, like this between double-deck rear arch, just define a space as gas combustion chamber, thus achieve not only can burning solid, but also can the object of combustion gas.
The further technical scheme of the utility model is: be all provided with secondary air channel in upper strata rear arch and lower floor's rear arch, and the mouth of pipe of described secondary air channel penetrates the front end of upper and lower layer rear arch, communicates with burner hearth.In the rear arch of the upper and lower, arrange secondary air channel, can multistage combustion be realized, reduce the generation of nitrogen oxide.Than at face arch and burner hearth side wall, this arranges that the routine techniques of secondary air channel is more effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, preferred embodiment of the present utility model is: a kind of gas-solid double fuel boiler, comprise feed hopper 1, chain or reciprocal grate 2, burner hearth 9, boiler convection bank 7, upper strata rear arch 3 and lower floor's rear arch 4, be gas combustion chamber 5 between upper and lower layer rear arch 3,4, gas combustion chamber 5 front end communicates with burner hearth 9, and rear end is provided with gas burner system 6, the gas flame that combustor 6 sprays moves from back to front, enters boiler furnace 9 from gas combustion chamber 5; Chain or reciprocal grate 2 are positioned at the below of lower floor's rear arch 4, and the biomass granule fuel of solid inputs from the feed hopper 1 being positioned at boiler front portion, drives, move from front to back through chain or reciprocal grate 2.All be provided with secondary air channel 8 in upper strata rear arch 3 and lower floor's rear arch 4, the mouth of pipe of described secondary air channel penetrates the front end of upper and lower layer rear arch 3,4, communicates with burner hearth 9.
Claims (2)
1. a gas-solid double fuel boiler, comprise feed hopper, chain or reciprocal grate, burner hearth and boiler convection bank, it is characterized in that: also comprise upper strata rear arch and lower floor's rear arch, be gas combustion chamber between upper and lower layer rear arch, gas combustion chamber front end communicates with burner hearth, rear end is provided with gas burner system, and the gas flame of combustor ejection moves from back to front, enters boiler furnace from gas combustion chamber; Chain or reciprocal grate are positioned at the below of lower floor's rear arch, and solid fuel, from the feed hopper input being positioned at boiler front portion, drives through chain or reciprocal grate, moves from front to back.
2. gas-solid double fuel boiler according to claim 1, is characterized in that: be all provided with secondary air channel in upper strata rear arch and lower floor's rear arch, and the mouth of pipe of described secondary air channel penetrates the front end of upper and lower layer rear arch, communicates with burner hearth.
