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 communicated with 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
The present invention relates to the oil field and produce the belt length naked light fuel gas combustion system of the combustion system, particularly a kind of heater of building heater in the engineering, it is applicable to the heater that middle-size and small-size gathering station field, oil field adopts associated gas or natural gas to act as a fuel.
Background technology
Middle-size and small-size gathering station field, oil field main oils firing equipment is vertical water batch heater at present, be the nineties exploitation in last century and come into operation, shortcomings such as its burner ubiquity burning and heat-transfer intensity is little, efficient is low, adaptability and poor stability, fluctuation of service.
Summary of the invention
The purpose of this invention is to provide that a kind of heat-transfer intensity is big, efficient is high, adaptability and good, the stable belt length naked light fuel gas combustion system of security.
The object of the present invention is achieved like this, a kind of belt length naked light fuel gas combustion system is provided, it is characterized in that: fuel gas enters combustion system through fuel gas import, main valve, combustion system comprises filter, magnetic valve, gate valve, control valve and burner, be divided into two-way after fuel gas filters through filter and pressure-reducing valve reduces pressure, one the tunnel comprises successively magnetic valve, gate valve and the control valve that connects, and control valve is communicated with the main nozzles of the burner of natural induced air type again; Another road is communicated with the nozzles kept burning day and night of natural induced air type burner by gate valve.
Described burner adopts nature air inducing diffusion type, forced-air blast formula or premixing combuster, and forced-air blast formula burner is connected with blower fan, and blower fan is provided with volume adjusting apparatus.
Igniter is arranged at described burner cavity bottom, and inside is provided with flame detecting device, and by the flame detecting device flame detection, when flame was arranged, magnetic valve was opened; During fray-out of flame, magnetic valve disconnects; Temperature transmitter is arranged in the burner, detect the heated medium temperature,, the heated medium temperature is within 85 degree-95 degree scopes by the size of control and regulation valve opening degree by the temperature transmitter in the heated medium.
Characteristics of the present invention are: filter post-decompression fuel gas and be divided into two-way, the one tunnel enters burner through magnetic valve, gate valve and control valve, uses for burner master fire; Another road enters burner by gate valve, uses for the burner ever-burning flame.This employing ever-burning flame adds main fire design, and main fire burns can adopt nature air inducing diffusion type, forced-air blast formula or premix box-like, flame is set detects in conjunction with combustion completion protective devices such as auto extinguishing protections.
Description of drawings
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is embodiment 1 schematic diagram;
Fig. 2 is embodiment 2 schematic diagrames.
Among the figure: 1, fuel gas import; 2, main valve; 3, filter; 4, pressure-reducing valve; 5, magnetic valve; 6, gate valve; 7, gate valve; 8, control valve; 9, burner; 10, flame detecting device; 11, main nozzles; 12, nozzles kept burning day and night; 13, igniter; 14, blower fan; 15, volume adjusting apparatus.
The specific embodiment
Embodiment 1 as shown in Figure 1, it is nature air inducing diffusion type (perhaps premix is a box-like) belt length naked light fuel gas combustion system schematic diagram; Fuel gas (associated gas or natural gas) enters combustion system through fuel gas import 1, main valve 2, combustion system comprises filter 3, pressure-reducing valve 4, magnetic valve 5, gate valve, control valve 8 and burner 9, be divided into two-way after fuel gas filters through filter 3 and pressure-reducing valve 4 reduces pressure, one the tunnel is communicated with the main nozzles 11 of burner 9 through magnetic valve 5, gate valve 6 and control valve 8, uses for burner master fire; Another road is communicated with the nozzles kept burning day and night 12 of the burner 9 of natural induced air type by gate valve 7, for the ever-burning flame use of burner 9.
Embodiment 2 as shown in Figure 2, it is a forced-air blast formula belt length naked light fuel gas combustion system, its difference from Example 1 is that burner 9 is forced-air blast formula burners, it is connected with blower fan 14, the purging and the required combustion air that burns provide by blower fan 14 before and after burner 9 igniting, and blower fan 14 is regulated by volume adjusting apparatus 15 to burner 9 required combustion-supporting air quantities.
Igniter 13 is arranged at burner 9 cavity bottoms, and inside is provided with flame detecting device 10, and by flame detecting device 10 flame detection, when flame was arranged, magnetic valve 5 was opened; During fray-out of flame, magnetic valve 5 disconnects; Reach the purpose of automatic protection burner 9.In the burner 9 temperature transmitter is arranged, detect the heated medium temperature by the temperature transmitter in the heated medium, size by control and regulation valve 8 opening degrees, the heated medium temperature is within the zone of reasonableness, under normal condition, the heated medium temperature is controlled within 85 degree-95 degree scopes.
Filter among the present invention, pressure-reducing valve, magnetic valve, gate valve, control valve, burner, flame detecting device, igniter, blower fan, volume adjusting apparatus can the outsourcing gained, so need not describe in further detail.
