Abstract
The utility model provides a large -scale oil field gas injection boiler hangs down nitrogen fuel ware mainly includes: center plenum, combustor, secondary plenum, secondary air channel, central air pipe, ejector and circular flue, wherein: the air current is to through air inlet, air adjusting valve, cyclone, central plenum, secondary plenum, overgrate air spout in the combustor, overgrate air flow through in proper order secondary plenum, overgrate air spinning disk, secondary air channel, central air pipe sets up in the secondary air channel, and the center pin of central air pipe and secondary air channel is all on central plenum axis, the combustor is on the axis of central plenum, the combustor includes fuel injector, ejector, nozzles, circular flue is still connected to the combustor. The utility model provides a circular flue is not only gone into to the fuel ware, utilizes back cigarette technique to reduce oxynitrides, use wind through hierarchical tissue burning again, the fractional combustion of realization crude oil, further reduction oxynitrides's emission.
Description
Technical field
The utility model belongs to fuel-device field, and in particular to a kind of low nitrogen fuel device of large oilfield gas boiler.
Background technology
In July, 2013, Shandong Province issues《Shandong Province's regionality discharge standard of air pollutants》, it is stipulated that by 2017
No. 1 oil burning boiler nitrogen oxide discharging standard of January in 250mg/Nm3Within, to the year two thousand twenty January 1, oil burning boiler nitrogen oxides
Discharge capacity is in 200mg/Nm3Within.But because existing steam-injected boiler fuel device is burnt using high excess air coefficient, and tie
Structure is simple, and tissue wind is single, causes discharged nitrous oxides exceeded, improves steam-injected boiler efficiency of combustion and reduces the row of nitrogen oxides
Putting becomes the task of top priority of steam-injected boiler industry.
Utility model content
The utility model provides a kind of low nitrogen fuel device of large oilfield gas boiler and adds not only to enter to follow for solution Problems Existing
Annular smoke flue, utilizes back cigarette technology to reduce oxynitrides, further through hierarchically organized burning wind, realizes the fractional combustion of crude oil,
The further discharge capacity for reducing oxynitrides.
What the utility model was achieved through the following technical solutions：
A kind of low nitrogen fuel device of large oilfield gas boiler, mainly includes：Center air compartment, burner, secondary air chamber, Secondary Air
Pipe, central air hose, injector and cycle flue, wherein：Air flow Jing air intakes, air control valve, whirlwind in burner
Device, center air compartment, secondary air chamber, overfire air port；Secondary Air flows through successively secondary air chamber, Secondary Air spinning disk, secondary air channel；
The central air hose is arranged in secondary air channel, and the central shaft of central air hose and secondary air channel is on centre wind chamber axis；Institute
Burner is stated on the axis of center air compartment, the burner includes fuel nozzle, injector, nozzles, the burner also connects
Connect cycle flue.
The Secondary Air spinning disk is connected with secondary air regulation device.
The nozzles are provided with fire hole.
The utility model fuel sprays into injector from the nozzle of burner in free jet mode, is internally formed in injector
One low-pressure area, so as to the flue gas of cycle flue is sucked into injector, after circulating flue gas mix in injector, on Jing nozzles
Fire hole sprays into center air compartment, and from central air hose quantitative centre wind is passed through, and centre wind is sufficiently mixed at fire hole with mist of oil and makes combustion
Burn more fully, opened by secondary air regulation device secondary air duct according to case of fire, adjust the air quantity and eddy flow angle of Secondary Air,
So that fully burning in the case where loading condiction is met, formation of nitrogen oxides is reduced.
The beneficial effects of the utility model are：
The fuel device that the utility model is provided not only enters cycle flue, utilizes back cigarette technology to reduce oxynitrides, leads to again
Hierarchically organized burning wind is crossed, the fractional combustion of crude oil is realized, the further discharge capacity for reducing oxynitrides.
