Description
Technical field
The present invention relates to a kind of horizontal type condensation jacket heater, belong to oil field special heating furnace technical field.
Background technology
Station in oilfield special heating furnace mainly adopts vertical and horizontal two kinds, mainly undertake the heat supply task of oil gas field, be one of maximum consumable fuel apparatus of oil gas field, the height of its technical merit and the thermal efficiency directly affects technical merit that oil-gas field surface engineering builds, energy-saving and emission-reduction and economic benefit.In recent years, water batch heater is widely used in oilfield surface engineering with its reliable security performance.But water batch heater generally limits by dew-point temperature, high fume temperature, energy in flue gas and steam latent heat can not be used effectively (vacuum drying oven and tubular heater also exist problems), cause that the water batch heater thermal efficiency is low, the problem such as energy waste and environmental thermal pollution.
Mainly there is following problem in the water batch heater in application:
One. the efficiency of heating surface is not high: although the design stove effect of heating furnace is general about 90%, the actual motion thermal efficiency of oil field major part water jacket furnace is not high, and principal element has following several respects:
1. the heat convection of water jacket furnace self structure defective effect flue gas and smoke pipe, also affects the heat exchange of heated medium and heat(ing) coil, thus reduces the thermal efficiency;
2. because water jacket furnace is by the restriction of flue gas dew point temperature, cause exhaust gas temperature higher (other heating furnace also exists this problem), the efficient heat in flue gas can not make full use of, thus reduces the thermal efficiency;
3. water jacket furnace own combustion device efficiency is not high.Conventional negative-pressure ejecting scroll casing type burner stove tank flame temperature is not high, and radiation intensity is low, reduces efficiency of combustion;
4. water jacket furnace insulation is bad, and operational management is not in place, reduces heater efficiency.
Two. water jacket furnace is superfluous and air coefficient is bigger than normal:
Because burner type selecting is improper, the on-the-spot water jacket furnace run is superfluous, and air coefficient major part is higher, how to run between 2.0 ~ 3.0, does not reach optimum value.Best excess air coefficient should control by different combustion systems, should control between 1.05 ~ 1.20 for pressurized firing, for should controlling between 1.4 ~ 2.0 of gravity-flow ventilation burning.
Three. the perishable perforation of water jacket furnace causes leakage, and service life is shorter:
The weld seam at smoke-fire-tube and burner hearth connecting bend place occurs to leak the corrosion causing water jacket furnace, and one of reason is the corrosion that the condensation water in natural gas causes, and namely water jacket furnace temperature degree of using by oneself is not high, and the easy condensation of the saturated steam in natural gas becomes aqueous water, is ionized into H

3, at high temperature under high pressure, exacerbate the corrosion of pyrotechnics pipeline and weld seam.Two of reason is that water jacket furnace adopts " U " structure, and pyrotechnic system easily connects the commissure generation corrosion failure at tube sheet place at smoke pipe, front and back tube sheet and smoke pipe and leaks, the electrochemical corrosion that the condensation water produced after also having right gas firing causes.
Four. the metering of water jacket furnace is general not up to standard:
Owing to gratuitously can use associated gas in Oil and gas station, build fund for saving product, heating furnace does not all implement separate unit combustion gas and quantity of heat given up metering by regulation, causes the gas consumption that accurately cannot obtain water jacket furnace.
Five. there is weak link in water jacket furnace operation operational management:
Do not set up the judgement start and stop method of a set of science, do not determine the start and stop of stove according in station by the relativeness of medium temperature in hot factor and stove, only often open stove or time delay blowing out ahead of time with sensation by rule of thumb, extend the running time of stove, cause energy waste.Lack the technical skill training to employee, do not form regular maintenance system.In the long-time water batch heater used, burner and blocking water corrosion phenomena of sealing up a door is general, the phenomenons such as internal structure blocking, gas nozzle ablation and induction tunnel damage occur often, the anhydrous gentle exhaust gas temperature meter of water batch heater or temperature reading distortion, water blind roaster level gauge instruction is unintelligible, smoke-fire-tube fouling.
