Abstract
The utility model discloses a mutation transition fuel gas pulse combustion heater of a premixer, which mainly solves the problem that tail pipes of an existing heater are unlikely to increase. The mutation transition fuel gas pulse combustion heater is characterized in that a combustible gas premixer (6) is communicated with a combustor (7), and the difference between the combustor (7) and the combustible gas premixer (6) is a positive value; more than two tail pipes (8) communicated to the periphery of the right end of the combustor (7) are communicated with an exhaust decoupling device (9), and a smoke discharging pipe (10) is communicated with the exhaust decoupling device (9); the periphery of the left end of the combustible gas premixer (6) is communicated with 1-4 air inlet channels (2) and a fuel inlet pipe (4), the air inlet channels (2) and the fuel inlet pipe (4) are communicated with an air valve (1) and a fuel valve (3), the inner end of the fuel inlet pipe (4) is connected with a fuel nozzle, and a sparking plug base (5) on the left end surface of the combustible gas premixer (6) is connected with a sparking plug. The mutation transition fuel gas pulse combustion heater of the premixer provided by the utility model has the characteristic that tail pipes are convenient to increase.
Description
Technical field
The utility model relates to a kind of field joint stations heating furnace heater used, especially premixer's sharp transition fuel gas intermittent combustion heater.
Background technology
Heater is applied existing nearly 20 years history on oil field heating furnace, and under identical thermal power, the steel consumption of heater is only 50% left and right of other heating furnaces, and stove is imitated but than high 2% left and right of other heating furnaces.But because reasons in structure exists the quantity of tail pipe, be difficult to increase, the thermal efficiency can not continue the problem improving, and is unfavorable for applying.
Summary of the invention
In order to solve the quantity of existing heater tail pipe, be difficult to the problem increasing.The utility model provides a kind of premixer sharp transition fuel gas intermittent combustion heater.This premixer's sharp transition fuel gas intermittent combustion heater has the feature of the quantity increase of being convenient to tail pipe.
The technical solution of the utility model is: this premixer's sharp transition fuel gas intermittent combustion heater comprises air valve, free-air diffuser, fuel valve, fuel inlet pipe, spark plug adapter, fuel gas premixer, combustion chamber, tail pipe, exhaust decoupling device and smoke exhaust pipe.Cylindrical shape fuel gas premixer is connected with throat less chamber, the difference of combustion chamber and fuel gas premixer be on the occasion of; On the right-hand member circumference of combustion chamber, be communicated with 2 last person's pipes, every row 4-25 root tail pipe, tail pipe right-hand member is connected with exhaust decoupling device, on exhaust decoupling device, is communicated with smoke exhaust pipe; On fuel gas premixer left end circumference, be communicated with 1-4 free-air diffuser and fuel inlet pipe, on free-air diffuser, be communicated with air valve, on fuel inlet pipe, be communicated with fuel valve, fuel inlet pipe the inner is connected with fuel nozzle, fuel gas premixer is connected with spark plug adapter on left side, is connected with spark plug on spark plug adapter.
The utlity model has following beneficial effect: this premixer's sharp transition fuel gas intermittent combustion heater is owing to adopting cylindrical shape fuel gas premixer to be connected with throat less chamber, the difference of combustion chamber and fuel gas premixer be on the occasion of; On the right-hand member circumference of combustion chamber, be communicated with 2 last person's pipes, every row 4-25 root tail pipe, tail pipe right-hand member is connected with exhaust decoupling device, on exhaust decoupling device, is communicated with smoke exhaust pipe; On fuel gas premixer left end circumference, be communicated with 1-4 free-air diffuser and fuel inlet pipe, on free-air diffuser, be communicated with air valve, on fuel inlet pipe, be communicated with fuel valve, fuel inlet pipe the inner is connected with fuel nozzle, fuel gas premixer is connected with spark plug adapter on left side, is connected with the structure of spark plug on spark plug adapter.Utilize and increase combustion chamber diameter, thereby be convenient to the quantity increase of tail pipe.This premixer's sharp transition fuel gas intermittent combustion heater has the feature of the quantity increase of being convenient to tail pipe thus.
accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
1-air valve in figure, 2-free-air diffuser, 3-fuel valve, 4-fuel inlet pipe, 5-spark plug adapter, 6-fuel gas premixer, 7-combustion chamber, 8-tail pipe, 9-exhaust decoupling device, 10-smoke exhaust pipe.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this premixer's sharp transition fuel gas intermittent combustion heater comprises air valve 1, free-air diffuser 2, fuel valve 3, fuel inlet pipe 4, spark plug adapter 5, fuel gas premixer 6, combustion chamber 7, tail pipe 8, exhaust decoupling device 9 and smoke exhaust pipe 10.Cylindrical shape fuel gas premixer 6 is connected with throat less chamber 7, the difference of combustion chamber 7 and fuel gas premixer 6 be on the occasion of, namely the diameter of fuel gas premixer 6 is less than combustion chamber 7 diameters; On the 7 right-hand member circumference of combustion chamber, be communicated with 2 last persons and manage 8, every row 4-25 root tail pipe 8, tail pipe 8 right-hand members are connected with exhaust decoupling device 9, are communicated with smoke exhaust pipe 10 on exhaust decoupling device 9; On fuel gas premixer 6 left end circumference, be communicated with 1-4 free-air diffuser 2 and fuel inlet pipe 4, on free-air diffuser 2, be communicated with air valve 1, on fuel inlet pipe 4, be communicated with fuel valve 3, fuel inlet pipe 4 the inners are connected with fuel nozzle, fuel gas premixer is connected with spark plug adapter 5 on 6 left sides, on spark plug adapter 5, is connected with spark plug.
Because air and fuel have completed in fuel gas premixer 6, swash mutually formula and mix, after the changeover portion connecting enters combustion chamber 7, just can burn more fully through sudden change.Therefore for reducing tail pipe 8 diameters and accelerating, provide condition, in the situation that not changing combustion chamber 7 diameter dimension, before and after tail pipe is divided, two rows are arranged on the excircle of combustion chamber 7 other ends.After tail pipe 8 diameters reduce, can make ripple frequency increase, the hot flue gas in every pipe and the heat exchange meeting of tube wall are more abundant, and the hot flue-gas temperature that tail pipe 8 heart portions discharge will decline, and total exhaust gas temperature also will decline, and stove effect will improve a lot.If still by single layout, just that combustion chamber 7 diameters will add is much larger, combustion chamber 7 diameters become will reduce ripple frequency greatly, thereby reduce heat exchange efficiency in the situation that tail pipe 8 quantity increase, and then affect stove and imitate.
