Embodiment 1

[0012] Example 1 as figure 1 As shown, it is a schematic diagram of a natural draft diffusion (or pre-mixed) gas combustion system with an open flame; fuel gas (oilfield associated gas or natural gas) enters the combustion system through fuel gas inlet 1 and main valve 2, and the combustion system includes filtration Device 3, pressure reducing valve 4, electromagnetic valve 5, gate valve, regulating valve 8 and burner 9. The fuel gas is filtered by filter 3 and decompressed by pressure reducing valve 4. And the regulating valve 8 is connected with the main burner 11 of the burner 9 for the main fire of the burner; the other way is connected with the permanent burner 12 of the natural draft type burner 9 through the gate valve 7 for the permanent flame of the burner 9 use.

Embodiment 2

[0013] Example 2 as figure 2 As shown, it is a forced-air gas combustion system with an open flame, and it differs from Embodiment 1 in that the burner 9 is a forced-air burner, which is connected with a blower fan 14, and the burner 9 is ignited before and after purging and The combustion-supporting air required for combustion is provided by the fan 14 , and the amount of combustion-supporting air required from the fan 14 to the burner 9 is regulated by the air volume regulating device 15 .

[0014] There is an ignition device 13 at the lower part of the burner 9 cavity, and a flame detection device 10 is arranged inside, and the flame is detected by the flame detection device 10. When there is a flame, the solenoid valve 5 is opened; when the flame is extinguished, the solenoid valve 5 is disconnected; to achieve automatic protection of combustion The purpose of device 9. There is a temperature transmitter inside the burner 9. The temperature of the heated medium is detect...

Abstract

The invention relates to a combustion system for heating devices in oilfield production-construction projects, in particular to a heating-device gas combustion system with eternal flame, which is characterized in that a fuel gas inlet of a fuel gas inlet pipe is connected with a master valve, a filter and a pressure-reducing valve in turn; the outlet end of the fuel gas inlet pipe is communicatedwith two gas pipes; one gas pipe is connected with an electromagnetic valve, a gate valve and a regulating valve, and is communicated with a main flame nozzle of a burner in turn; and the other gas pipe is communicated with an eternal-flame nozzle of the burner through the gate valve. The combustion system adopts the design with eternal flame and main flame, and the combustion of the main flame can adopt a natural air inducing-diffusing mode, a forced-air blast mode or a premixing mode. The combustion system which is provided with flame detection combined with automatic flameout protection and other combustion safety protection devices applies to the heating devices adopting oilfield associated gas or natural gas as fuel in oilfield medium / small-sized gathering-transferring station yards.

Description

technical field [0001] The invention relates to a combustion system of a heating device in an oilfield production and construction project, in particular to a gas combustion system with an open flame for the heating device, which is suitable for a heating device using oilfield associated gas or natural gas as fuel in small and medium-sized oilfield gathering and transportation stations. Background technique [0002] At present, the main crude oil heating equipment in small and medium-sized oil gathering and transportation stations is a vertical water jacket heating furnace, which was developed and put into use in the 1990s. The burners generally have low combustion and heat transfer intensity, low efficiency, poor adaptability Poor security, unstable operation and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to provide a gas combustion system with an open flame with high heat transfer intensity, high efficiency, good adapta...
