Abstract
The invention discloses a gas-solid dual-fuel boiler which comprises a feeding hopper, a chain or reciprocating grate, a hearth, a boiler convection bank, an upper-layer rear arch and a lower-layer rear arch. A gas combustion chamber is arranged between the upper-layer rear arch and the lower-layer rear arch. The front end of the gas combustion chamber is communicated with the hearth. The rear end of the gas combustion chamber is provided with a gas combustion engine. Gas flames injected by the combustion engine move from back to front and enter the hearth of the boiler from the gas combustion chamber. The chain or reciprocating grate is located below the lower-layer rear arch. Solid fuel is input from the feeding hopper located at the front portion of the boiler and is driven by the chain or reciprocating grate to move from front to back. According to the gas-solid dual-fuel boiler, the chain or reciprocating grate technology is adopted, an existing single-layer rear arch is replaced with the dual-layer rear arch, the space used as the gas combustion chamber is formed between the upper-layer rear arch and the lower-layer rear arch, and therefore both the aim of solid combustion and the aim of gas combustion can be achieved.
Description
Technical field
The present invention relates to a kind of boiler, especially a kind of not only can burning solid, but also boiler that can 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, still, on a large scale coal-burning boiler is changed into gas fired-boiler and exists again the problems such as source of the gas deficiency.
Gas-solid double fuel boiler can adapt to the demand of this situation.First, while not possessing combustion gas condition, this boiler can solid be fuel, waits while possessing gas supply condition in the future, and this boiler is gas fired directly.Secondly, if two kinds of fuel have, but fuel supply is unstable, with season, change with fuel reserve situation, only with gas not, only there is season limit by living beings, this boiler also can solve this and make us awkward problem.
But existing gas-solid double fuel boiler grows up on pulverized-coal fired boiler basis, its combustion system is chamber combustion, and solid fuel must first be clayed into power, and just can spray into boiler combustion, and the investment of abrasive dust equipment is huge, has even exceeded the price of boiler main frame.And invest the wide grate firing boiler such as chain, reciprocal grate of little application owing to being subject to the restriction of fire grate and individual layer chimney arch, and be only limited to solid-fuelled burning always, before this patent, not yet there is gas-solid double fuel grate firing boiler technology.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of not only can burning solid, but also chain or reciprocating-grate boiler that can combustion gas.
For solving the problems of the technologies described above, technical scheme of the present invention 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, between upper and lower layer rear arch, it is gas combustion chamber, gas combustion chamber's 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 being positioned at the feed hopper input of boiler front portion, drives through chain or reciprocal grate, from front to back motion.
Boiler of the present invention adopts chain or reciprocal grate technology, and existing individual layer rear arch is changed into double-deck rear arch, between double-deck rear arch, just form a space as gas combustion chamber like this, can burning solid thereby realized not only, but also object that can combustion gas.
The further technical scheme of the present invention is: in upper strata rear arch and lower floor's rear arch, secondary air channel is all installed, 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 realize multistage combustion, reduce the generation of nitrogen oxide.This is than arranging that at face arch and burner hearth side wall the routine techniques of secondary air channel is more effective.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the preferred embodiments of the present invention are: 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, between upper and lower layer rear arch 3,4, be gas combustion chamber 5, gas combustion chamber's 5 front ends communicate 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 is inputted from the feed hopper 1 that is positioned at boiler front portion, drive, from front to back motion through chain or reciprocal grate 2.The interior secondary air channel 8 that is all provided with of 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, between upper and lower layer rear arch, it is gas combustion chamber, gas combustion chamber's 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 being positioned at the feed hopper input of boiler front portion, drives through chain or reciprocal grate, from front to back motion.
2. gas-solid double fuel boiler according to claim 1, is characterized in that: in upper strata rear arch and lower floor's rear arch, secondary air channel is all installed, the mouth of pipe of described secondary air channel penetrates the front end of upper and lower layer rear arch, communicates with burner hearth.
