Henan Notes horizontal low pressure boiler gas leak problem Henan precautions gas boiler leaking problem: ① the inner wall of the Henan gas boiler leaks: leak is also divided into the inner wall of the drum and the provision of water leakage and water cooling pipe leakage drop, if the former is relatively small leakage eye, can be Wabu same steel, after Patching flaw detection. Leak needs to be replaced before the tube, replacing a large area. ② Henan leaking gas boiler handhole: re-try transducer mounted at an angle, to see if there is a hand hole cover deformation, if deformed, the first correction, and then the green tape wrapped in a layer of a uniform mat, and preferably consistent position before overhaul . ③ gas leak in the boiler drum: the higher cost of repair costs, mainly to see the location and size of the leak leak point where, if the old boiler appears oozing red pot of water, indicating that water quality problems, probably because of low alkalinity or water metal corrosion caused by dissolved oxygen is too high. Low alkalinity can adding sodium hydroxide or trisodium phosphate to a pot of water, dissolved oxygen in water is too high to be resolved by the deaerator. ④ leaking water treatment system: first check whether the gas boiler corrosion, if you need to descaling the boiler corrosion, leaks repaired part, and then circulating water treatment, adding agents, equipment and other materials were boiler corrosion, scale, protection . ⑤ boiler flue gas leak: check is not the boiler tube or tube sheet due to cracks, if the need to change the pipe, see Wabu flue used material, aluminum, and stainless steel may be carbon steel or argon welding aluminum wire, iron acid electrode material directly. ⑥ leaking valves: Valves leaking packing should be added to or replacement of the valve.
Boiler furnace excess air control how to adjust? Boiler furnace combustion furnace excess air affects, therefore, how to effectively control the excess air ratio, is one of the prerequisites to protect the horizontal low pressure boiler reasonable run. Today to excess higher degree of automation of the gas boiler furnace air as an example to explain:

Boiler where the water is deflated Editor's Note steam horizontal low pressure boiler output has a certain heat, hot water or organic heat carrier, like this small, we generally use at home, where some users find their home devices easily deflated water the following'll tell you about the reasons local device deflated effluent: 1, high water: solution, lowering the water level. 2, in a boiler, particularly high temperatures, mainly in the form of a gas water - vapor. 3, there may be too hot, and the water vapor liquefied results. 4, steam separator fault: Call service sale or the manufacturer may want to add water, the water is heated after coming out. 5, the accumulation of water vapor at the exit, it is the droplets merged into the water droplets, and then turned to water. Mainly deflated mouth, will be more pronounced in winter, the water will be more. 6, when the play an open gas: ① ambient temperature is much lower than the temperature in the boiler, the steam case of cold physical reactions occur - liquefaction, the liquefied gas is at home high pressure low temperature combustible gas such as natural gas stored in liquid form in a tank in. ① The product is liquefied initial liquid - water vapor, and steam different note, means water vapor gas are all present, and the water vapor and liquid water refers to gas co-exist, i.e. small droplets. 7, in fact, generally do not change the water boiler, new water easily bring new scale and oxygen, corrosion periodic discharge of sewage on it, a little water color is not a problem. Suggest that you change once a year or two. We can not ignore in daily use in maintenance and cleaning of the boiler, where the water simply deflated we can repair it yourself, if you feel the quality really can not hold on, and on equipment, not to hazard my side.
