Flameless gas burner

The utility model relates to the oil and gas industry and can be used in well testing or at offshore oil and gas facilities.

A device for the study of gas condensate wells, containing an ejector with inlet and pressure pipes, nozzle, confusers, socket and control devices A.S. Ks 1105624.1984 g.

A disadvantage of the known device is that when burning a gas-gas mixture on a flare, the presence of heavy hydrocarbons and a dropping liquid in n reduces the temperature of the flare. At the same time, at a combustion temperature of less than 1600 ° C, there is an “underburning of heavy hydrocarbons, which leads to soot formation, and at a combustion temperature in excess of which carcinogenic oxides are formed.

The technical task of the proposed utility model is to develop a device design that provides an increase in the temperature of combustion of the flare gas due to preliminary purification, reduction and heating of the source gas.

The usefulness of the proposed utility model consists in the fact that the device for the sootless burning of fassel gas contains the inlet and outlet pipes (ejector, nozzle, confusers, conical bell) connected to the source of the source gas; the conical bell is muffled with a diffuser with a g (g) and a coil heater is placed outside the diffuser and conical bell, the beginning of which is connected by pipelines to a separator and dispersant with an inlet pipe, and the end with an entrance to the ejector nozzle, etc. This ejector nozzle confusers, discharge nozzle, socket and konusnSh diffuser grating and a combustion stabilizer zmeevnkovym heater enclosed in a box, which serves as a heating chamber ozduul,

Such a design of the device will provide preliminary reflux of the source gas from heavy hydrocarbons and harmful admixtures, as well as preliminary heating of the gas, while burning a hot gas-air mixture on a flare, the temperature of the flare is increased, excluding soot.

The drawing schematically shows the proposed device.

The device contains:

inlet pipe I; dispersant 2, separator 3 and heating chamber 4 interconnected by pipelines 5,6,7,8 and 9. In this case, KaMq) a heating 4 includes: an ejector 10, a calibrated working nozzle 11, confusers 12 and a discharge pipe 13, {not laid horizontally on one axis, and the concentrically made confusers are directed into the discharge pipe 13, at the output of which a conical bell 14 and a diffuser 15 are installed, made in the form of a continuation of the bell. There is a gap 16 between the end of the cone socket 14 and the beginning of Jffffyus 15 16. A gaseous gas stabilizer 17 is mounted inside the diffuser 15, and a coil heater 18 is placed outside the diffuser 15 and the cone 14, the beginning of which is connected by a pipe 8 to a separator 3, and the end of the pipe 9 is connected with the entrance to the calibrated working nozzle 11 of the ejector 10. In this case, the heating chamber 4 is made in the form of a duct made of thin-walled metal. The entire device is mounted on a frame 19, which can be fixed and / or stationary. When hot air-gas mixture is burned above the trellis stabilizer 17, a torch 20 is formed.

The device operates as follows,

During operation of the device, the source gas containing heavy hydrocarbons, harmful impurities and dropping liquid (oil, water) through the inlet 1 under high pressure comes into dispersant 2, suctioning atyphrase from the separator 3 through pipe 5, while the source gas due to random pressure mixes with antifreeze, which coagulates (precipitates) heavy hydrocarbons and squealing impurities. The fine-dispersed mixture of gas and antifreeze purified from heavy hydrocarbons and harmful impurities through pipeline 6 enters the separator 3, where the mixture is divided into 3 products: 1 - antifreeze that settles and accumulates in the bottom of the separator for reuse in dispersant 2:

2- gas gasoline - in the middle part, which goes through pipeline 7 for sale and

3- purified from heavy hydrocarbons and harmful impurities, stripped gas is collected in the upper part of the separator and through pipe 8 enters the coil heater 18 and then hot gas through t | the piping 9 enters the calibrated working nozzle 11 of the ejector 10, at the outlet of which a gas jet sucks at high speed through the confusers 12 the air from the heating chamber 4, entering it through the annular gap 16. The hot mixture of gas and air through the discharge pipe 13 is put into the conical the bell 14 and then to the lattice stabilizer 17, above which burns to form a torch 20 at a temperature in the range 1600 - -2000 ° C, depending on the composition of the source gas and

the presence of harmful impurities in it. The heat of the torch, washing the walls of the diffuser IS and the cone bell 14 is transferred to the coil heater 18, helping to increase the temperature of the purified and stripped gas passing through it, while heating the trellis stabilizer 17 and the chamber of the heating chamber 4, which is sucked in by a high-speed jet of hot gas along the line: confusers - pressure branch pipe - conical bell.

Thus, the heat obtained from burning hot gas, purified from heavy hydrocarbons and harmful impurities, and hot air, increases the temperature of the flare, providing it in the range of 1600-2000 ° C, which contributes to the continuous burning of flare gas stably and without flame failure.
