Abstract
The utility model relates to a furnace tube high-temperature checkout gear of a heating furnace, which belongs to a checkout device, the inner wall of a furnace body is fixed with a mounting head with a hole, a temperature checkout element is inserted into and inosculated with the hole of the mounting head to be fixed by a lock screw; a connection line of the temperature checkout element passes through the wall of a burner to be connected with a controller; high-temperature insulation material is coated outside the connection line of a hearth; and the controller is respectively connected with a fuel adjusting valve and a temperature transmitter which is connected with the temperature checkout element. The utility model has the advantages that the furnace tube high-temperature checkout gear accurately detects and controls the surface temperature of a heating furnace tube and a blowtube armor plate in real time, adjusts and controls the load of the heating furnace according to the detected temperature and thoroughly solves the occurrence of the accident that the furnace tube is burned out; the temperature checkout is reliable and the service life is long.
Description
Technical field
The utility model belongs to checkout gear, particularly relates to a kind of heating furnace tube high temperature checkout gear.
Background technology
Recovering the oil and the outer temperature that must utilize heating furnace to add deep fat and water in the process of failing in each oil field, increases mobile.Therefore, the quantity of each big or small oil field heating furnace, hundreds of platform at least, several thousand at most.Wherein the heating means of water jacket furnace and fire tube stove are flame directly-fired kiln pipe and fire tube.Medium in boiler tube and the fire tube is a water.Medium in the high efficiency furnace boiler tube is an oil.In order to improve the temperature of heated oil and water, improve heating furnace and load, must increase fuel quantity, the fuel quantity increase just increases the surface temperature of boiler tube, but in order to guarantee that boiler tube does not burn out, country and industry are all issued every kind of steel maximum temperature use standard.Yet, in flame zone, how to detect the steel tube surface temperature, also nobody solves this difficult problem so far.Up to the present, the surface temperature method that direct contact type detects heating furnace tube surface temperature and fire tube stove fire tube steel plate does not also have, and has only the surface temperature that detects steel pipe with contactless infrared temperature detector.As shown in Figure 1, the temperature of utilizing the contactless temperature measuring device A of infrared ray to watch the B position, in flame zone, when flame C, what the infrared temperature detector detected is the temperature of flame, is not to be the surface temperature of steel pipe and steel plate.Therefore, the standard of country also can't be carried out, and is example with the Daqing oil field, all has every year tens even up to a hundred heating furnace tube to burn out.And at least 20 ten thousand yuan of the maintenance costs of a stove, the present invention has successfully solved this difficult problem.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of direct contact type heating furnace tube high temperature checkout gear is provided, and can detect the true temperature on fire tube steel plate and boiler tube surface at flame zone, and error is little, long operational time.
Heating furnace tube high temperature checkout gear of the present utility model, be outside body of heater, to be provided with controller to constitute, be fixed with installation head with holes on inboard wall of furnace body, have detector unit to insert in the hole that head is installed, the wall that the connecting line of detector unit passes burner is connected with controller.
As further improvement of the utility model, the connecting line in burner hearth is coated with high temperature resistant heat insulation material.
As further improvement of the utility model, described detector unit is to make with the alloy armour.
As further improvement of the utility model, detector unit inserts in the hole that head is installed and fixes with screw with lock with its kissing merging.
As further improvement of the utility model, controller is connected with temperature transmitter with fuel control valve respectively, and temperature transmitter is connected with detector unit.
Heating furnace tube high temperature checkout gear of the present utility model, to because of bias current, excess load, fouling, reason such as the heat-insulation layer design is unreasonable and steel material is defective, burn out heating, it is perfectly clear to show, can show real time temperature, real-time curve, excellent figure curve, history curve, the alarm indication of each test point, and as required, before boiler tube burns out, the automatic blowing out of pre-alarm, warning and overtemperature is set.
Heating furnace tube high temperature checkout gear of the present utility model, surface temperature Detection ﹠ Controling accurately in real time to heating furnace tube or fire tube steel plate, and according to detected temperatures adjustment, control heating furnace load, thoroughly solved boiler tube and burnt out the generation of accident, detected temperatures accurately and reliably, long service life.
