Description
Technical field
The present invention relates to one kind burning nozzles, more particularly to a kind of ground flare burning nozzles.
Background technology
Recently as the introduction of external production technology, maximization, centralization trend is presented in the general layout of petroleum chemical enterprise,
A part essential as accident bleed-off system, flare system there has also been very big change, from original only overhead torch
Ground flare is developed into coexist with overhead torch, and ground flare is few due to taking up an area, easy to maintenance, safe and environment-friendly property is preferable,
Foreign countries have found broad application.
The characteristics of ground flare, has：1st, the heat radiation that torch spreads to surrounding is smaller, it is possible to reduce the area of guard plot；2、
Maintenance is convenient, and in addition to obturator is higher, remaining facility is on the ground；3rd, the sky to surrounding environment is reduced to greatest extent
Gas pollution, light pollution and noise pollution, improve the security of torch operation；4th, floor space is few, and ground flare is due to burning
Occur, on ground, fire rain will not occur.Based on ground flare it is above-mentioned the characteristics of, the beginning of the seventies in last century, foreign countries just set about ground
The research and development of torch, multiple types of floors flare discharge system is developed, be broadly divided into the multistage more burning nozzles of huge discharge and open
Formula ground flare and closed ground torch.China introduces and absorbed advanced foreign technology since the end of the nineties, particularly near
Nian Lai, country increase to natural gas demand, substantial amounts of LNG plant and liquefied natural gas receiving station have been built, so right
The demand of cryogenic natural gas ground flare surges.
Torch burning nozzles are a parts in flare system, and the torch combustion of many quantity is had in flare system
Make a fire mouth, and main effect is to handle discharge cryogenic natural gas by combustion system.Existing cryogenic natural gas ground flare combustion
The mouth that makes a fire is crotch formula structure, is distributed six crotch formula transverse tubes on each nozzles that burn, cryogenic natural gas is by being arranged on transverse tube
On aperture diffuse burning.Following defect be present in burning in crotch formula torch burning nozzles：1st, because crotch formula structure is transferred
Position is relatively more, causes gaseous-pressure loss larger, while the treating capacity for being limited to the single burning nozzles of structure is smaller；2nd, due to
The cryogenic natural gas pressure of crotch formula inside configuration is bigger, and pressure distribution is uneven, particularly at burner port, due to pressure
It is excessive, easily there is de- fire and put out phenomenon, produce potential safety hazard and environmental pollution；3rd, structure is relative complex, fabrication cycle length,
Raw materials consumption is more；To solve the deficiency in above technology, it should provide a kind of mix flare burner.
The content of the invention
The technical problems to be solved by the invention are：For deficiency of the prior art, there is provided one kind burning nozzles, use
In cryogenic natural gas ground flare burning nozzles, its is simple in construction, reasonable in design, and cryogenic natural gas can be made fully mixed with air
