Description
Technical field
The present invention relates to the horizontal water batch heater of a kind of condensation, 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 consumable fuel apparatus of oil gas field maximum, the height of its technical merit and the thermal efficiency directly affects technical merit, energy-saving and emission-reduction and the economic benefit that oil-gas field surface engineering is built.In recent years, water batch heater is widely used in oilfield surface engineering with its reliable security performance.But water batch heater is limited by dew-point temperature generally, 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 of heating furnace is imitated generally in 90% left and right, the actual motion thermal efficiency of the most of water jacket furnace in oil field 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, thereby reduces the thermal efficiency;
2. due to water jacket furnace, be subject to 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, thereby reduces the thermal efficiency;
3. water jacket furnace self combustor 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 surplus and air coefficient are bigger than normal:
Because burner type selecting is improper, the water jacket furnace of on-the-spot operation is superfluous, and air coefficient major part is higher, how 2.0～3.0 operations, does not reach optimum value.Best excess air coefficient should be controlled by different combustion systems, for should being controlled between 1.05～1.20 of pressurized firing, for should being controlled 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 that causes water jacket furnace, and one of reason is the corrosion that the condensation water in natural gas causes, the personal temperature degree of water jacket furnace is not high, and the easy condensation of saturated steam in natural gas becomes aqueous water, is ionized into H

3, under HTHP, aggravated the corrosion of pyrotechnics pipeline and weld seam.Former two is therefore that water jacket furnace adopts " U " structure, and the commissure that pyrotechnics system easily connects tube sheet place at smoke pipe, front and back tube sheet and smoke pipe corrosion failure occurs and leaks, the electrochemical corrosion that also has the condensation water that produces after right gas firing to cause.
Four. the metering of water jacket furnace is generally not up to standard:
Owing to can gratuitously using associated gas in Oil and gas station, for saving the fund of building of producing, heating furnace is not all implemented separate unit combustion gas and quantity of heat given up metering in accordance with regulations, causes the gas consumption that cannot accurately 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,, according to determine the start and stop of stove in station by the relativeness of medium temperature in hot factor and stove, only often do not open ahead of time stove or time delay blowing out with sensation by rule of thumb, extended the running time of stove, cause energy waste.The technical skill training of shortage to employee, does not form regular maintenance system.In the long-time water batch heater using, burner and the blocking water corrosion phenomena of sealing up a door is general, the phenomenons such as internal structure obstruction, 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 indication is unintelligible, smoke-fire-tube fouling.
Summary of the invention
The object of the present invention is to provide the horizontal water batch heater of a kind of condensation, its service life is longer, and good manufacturability can make full use of steam potential and waste heat in flue gas, and energy utilization rate is high.
