Nanjing steam generators, sandwich pot with steam generator, steam generator how much money

1, fuel gas-fired boiler during operation Note the following points: (1) does not allow pressurized combustion or furnace smoke. (2) Fuel gas-fired boiler at the bottom of the plane can not land on the water, to prevent moisture corrosion. 2, the boiler runs every 2-3 weeks, should be checked again. 3, boiler every 3-6 months, should conduct a comprehensive inspection and maintenance shutdown. (1) internal and external boiler inspection, such as compression weld parts, steel inside and outside for corrosion phenomenon, if found serious flaws should be repaired, if the defect is not serious until the next time also repair shutdown, if there is suspicious, but does not affect safety during production, should be made to record for future reference. (2) checked the water in the boiler primer coating to prevent corrosion. 4, boilers and boiler base paint at least once a year. 5, the fuel gas boiler often of unused Maintenance: dry and wet two kinds of shutdown more than a month, should be taken care of dry method, the following can be wet month maintenance shutdown method. LSS is a vertical-type oil or gas boiler combustion bent water tube boilers. Biasing structure using curved pipes, high temperature discharged from the burner flame first scour furnace smoke pipe, and then enter the rotation after the second return from the smoke chamber consisting of curved pipes, www.zhengqifashengqi.com through the chimney into the atmosphere. Boiler equipped with a removable mosaic structure, the boiler maintenance is very convenient. Boilers with good technical performance burners, combustion using automatic ratio adjustment, feedwater automatic control, program start and stop, automatic operation and other advanced technologies, and has low water level alarm and low water level, high steam pressure, turn off automatic protection function . The boiler has a compact, safe, reliable, simple, quick to install, less pollution, low noise, high efficiency. Electric heating steam boiler is the electrical energy into heat of a new electric equipment, the design also follows the "Boiler Safety Supervision" and industry standards. By electrical heating equipment, furnace, safety accessories, strong, weak control systems and other components of heating equipment All components have national compulsory safety certification mark. Full immersion heating element is fixed to the flange, easy to change freely. Furnace electrical control cabinet using isolated manner, avoiding the heat aging electrical components affecting life. Heater selection of quality products at home and abroad, the normal life of about 20,000 hours, the thermal efficiency of nearly 99 percent, quiet, clean, in line with environmental requirements, does not emit NOx (nitrogen oxide) to the atmosphere. Run PLC control system, free operating button, Shipping indicator, touch screen panel display in English, the man-machine dialogue, operational authorization, real-time information, automatic page turning. Fuse circuit design, to ensure electrical harmonics are controlled effectively protect the safety of the power supply circuit. Power boiler control system host and isolated manner, to avoid interference and thermal aging electrical components electrical components. First, the acid lotion for different scale and metal materials in the boiler, should choose a suitable acid lotion and a co-solvent, usually selected as follows: 1) for silicate scale, you can add fluoride in hydrochloric acid (such as hydrofluoric acid , sodium fluoride, ammonium fluoride, etc.) cleaning; 2) sulfate for sulfate scale or mixed with silicate scale, should advance the transformation alkali cooking, then added with hydrochloric acid or hydrochloric acid fluoride cleaning; 3) carbonate scale, generally use hydrochloric acid cleaning; 4) for iron oxide scale, you can add fluoride or nitric acid washed in hydrochloric acid; 5) When the scale sample of copper, the cleaning fluid should be added to prevent copper additives. Generally use of thiourea and hydrochloric acid was added fluoride and other additives, or pickled with ammonia plus ammonium persulfate cleaning except copper; 6) containing austenitic steel boiler, prohibit the use of hydrochloric acid wash, generally you can use EDTA, an amino group sulfonic acid, citric acid, formic acid, acetic acid, glycolic acid, etc. for cleaning agents, while the selection of corrosion inhibitors and additives not containing halogens.
