ENERGY-EFFICIENT GAS-POWERED BURNER
FOR THE PYROTECHNICAL EQUIPMENT
OF OIL AND GAS ENTERPRISES
I. V. Dolotovskii
A design of a fuel-spray injection burner for replenishing the fuel of users of the equipment of oil and
gas companies is proposed. A schematic diagram of the newly developed burner design is presented
and engineering designs by means of which lesser speciﬁ c metal content is achieved than in existing
constructions described, the operational reliability improved, and the overhaul life increased. Effective
mixing of the fuel and air is realized in the new burner, overheating of the burner stabilizer prevented, and
failures in ﬁ ring are eliminated. The burner supports efﬁ cient combustion of gas fuel, including as well the
liquid phase components.
Keywords: fuel-spray injection burner, pyrotechnical equipment, efﬁ ciency, reliability, metal content.
At oil and gas enterprises, gas burners that function as components of the pyrotechnical equipment of the production
plants exert a special inﬂ uence on the reliability and energy efﬁ ciency indicators.
The following may be observed in the operation of existing gas burners in a given unit: reduced reliability (short operat-
ing period); low efﬁ ciency of combustion of gas (waste gases) in the burners of horizontal fuel-spray plants that does not corre-
spond to the corresponding requirements [1, 2] imposed on industrial burners; increased operating costs due to additional delivery
of an individual ﬂ ow of fuel gas (to the pilot burners of horizontal fuel spray plants) and increased electricity costs to run the fans
of double-wire blast burners (used in combustion-driven evaporation plants in regeneration of methanol and absorbent).
An innovative design of an injection burner without these drawbacks has been developed . Test models of the new
burner with nominal thermal conductivity of 70 kW, 1.5 MW, and 20 MW have successfully undergone trial operation in ﬁ re-
tube water heaters and on the combustion-driven evaporator of the methanol regeneration plant, as well as in the ﬁ re bench
used in testing of horizontal fuel-spray plants. Not only natural gas, but also the casing-head gas of oil and gas ﬁ elds that in-
clude liquid-phase combustible components, is used as the fuel. The burners assure effective combustion of the natural and
casing-head gases with least heat of combustion 10–45 MJ/m
, including inert components (nitrogen, carbon dioxide) and
corrosive-active components, over a broad range of values of the air-fuel ratio (1.02–3.0).
A diagram of a fuel-spray injection burner with thermal conductivity up to 1.5 MW is represented in Fig. 1 (longitu-
dinal section with burner situated in the burner throat or ﬁ re tube of a pyrotechnical plant). By comparison with existing de-
signs, the newly developed burner is characterized by lesser speciﬁ c metal content (15 kg/MW with recommended [1, 2]
metal content less than 25 kg/MW), operating reliability, and high combustion efﬁ ciency of the gas fuel, including as well any
In the operation of the burner, the fuel gas (containing a liquid phase – gas condensate) enters the gas nozzle from the
gas-feed stub pipe. The nozzle is equipped with a replaceable lining. As it travels through the lower generator of the gas-feed
stub pipe with peripheral channels in the lining, the gas condensate is distributed around the perimeter of the inner surface of
the gas nozzle and is effectively diffused as the gas jet enters from a central hole. The gas condensate aerosol discharged by
