Description
Technical field
The utility model relates to the low pressure steam boiler technical field, is a kind of novel, complete function, low-pressure steam generating means that applicability is wide.
Background technology
Low pressure steam boiler belongs to traditional small low-voltage steam generating equipment, in being mainly used in, central heating, domestic hot-water's preparation or the technology heating of field, open-air mining site station etc. of small size building.Low pressure steam boiler is based on coal-burning boiler at present, and modal steam boiler type is the reciprocating type chain bar oven.
Heating crude oil is an important key link in the oil gas field crude oil transmission technology.And along with the reduction of associated gas output, only associated gas can't satisfy the demand for fuel of heating crude oil in the crude oil transmission technology.Because fuel cost is higher, cheap coal becomes the main alternative fuel of associated gas inevitably, and coal-fired low-pressure boiler is progressively promoted in the oilfield stations field and come.But the part associated gas resource that the field of standing still exists can't rationally be utilized, and by torch burning emptying, causes the serious wasting of resources.
The utility model content
The purpose of this utility model is: a kind of oil gas field dual-purpose low-pressure steam generating means of coal gas is provided, make it to adapt to coal, two kinds of fuel of natural gas, with fire coal, separately independent setting of combustion gas two cover combustion systems, make device fire coal, combustion gas be independent of each other, can burn coal separately or burn gas separately, can realize that also coal gas burns simultaneously, thereby realize multiple compound mode coal-fired, combustion gas.Make full use of the associated gas resource of oilfield stations field, reduce crude oil transmission technology operating cost, widen low pressure steam boiler accommodation simultaneously.
The technical solution adopted in the utility model is: a kind of oil gas field mainly is made up of fire grate, coal bunker, preceding flue, collecting box pipe, water-cooling wall, novel drum, furnace wall, steelframe backplate, gas burner system etc. with the dual-purpose low-pressure steam generating means of coal gas.Be provided with the fuel gas combustion system of coal-fired flue-gas convection bank and separate configurations in the novel drum, and be immersed in the interior water-bath of drum.Fire grate, coal bunker, preceding flue, furnace wall and coal-fired flue-gas convection bank constitute coal-fired combustion system; Fuel gas combustion system and gas burner system constitute the combustion system of combustion gas; Fire grate adopts driven by power, mechanization degree height; Collecting box pipe is provided with sewage draining exit; Novel drum housing is provided with inspection manhole, hand hole, steam connection, condensate return pipe, safety valve connecting pipe, gauge manifold, atmospheric valve adapter, level instrumentation nozzle and water supplement port and takes over; Gas burner system adopts efficient negative-pressure firing machine.Coal-fired, fuel gas combustion system can heat the saturation water in installing respectively or simultaneously, and making it vaporization becomes the use of saturated vapor heat supply user, after the saturated vapor heat release is condensed into saturation water, gets back in the drum and heats, thereby finish a thermodynamic cycle.
Under this structure, since independent fully for the fuel gas combustion system of associated gas burning with fired coal combustion system for fired coal combustion, promptly can when the associated gas inadequate resource, increase coal-fired additional to give; Having can be when the associated gas resource be sufficient, and the fired coal combustion system stops transport; Can only start fuel gas buring equally to guarantee the device operation when the fired coal combustion system overhaul, preventing influences the system process operation because of parking maintenance.This device can make full use of the associated gas of field, oil gas field station, stops the wasting of resources.
The beneficial effects of the utility model are: a kind of oil gas field can not only be applicable to burning of coal with the dual-purpose low-pressure steam generating means of coal gas, and can adopt the associated gas at scene, oil field to act as a fuel, realize burning coal, burn gas or burn multiple combustion modes such as coal burning gas carries out simultaneously, wide adaptability; And device is coal-fired, gas burning system separates fully, and separate configurations is independent of each other, and guarantees stable equipment operation, extension fixture service life; Dispose efficient negative pressure gas burner system, need not power consumption, improve the operational efficiency of gas burning system; Can make full use of simultaneously the associated gas resource of oilfield stations field, save fire coal, reduce environmental pollution.
