1, the gas pressure is lower than the low voltage protection switch. On Check gas valves are open, if there is gas in the tank.
2, the gas pressure is higher than the pressure protection switch. Shut off valve, and check the pressure reducing valve or regulator box has failed.
3, steam boiler water level is too low, there is very low interlock. Boiler water level observation, grasp the true level, after manual Sheung Shui to eliminate problems.
4, gas steam boiler pressure is higher than the starting pressure. Natural gas and other boiler pressure to reduce the pressure to start, you can start properly.
Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work". Programs that: improve the mechanism of heating prices, heating prices reasonable development of clean, green electricity implement ultra-low emissions coal-fired power plants, a comprehensive clean canceled preferential tariff class of high energy-consuming industries unreasonable prices and other preferential policies. Off Area ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace).
According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage. Actively implement alternative heat source, deadline for shutting down the Guanzhong area below 100,000 kilowatts thermoelectric ratio does not meet the national standard or alternative heat source thermal units. Optimal operation mode cogeneration units, strictly implement the "hot set electricity."
10,000 square meters of workshops on how to buy a boiler inspection and maintenance Selection
I believe that every user in the initial purchase of the boiler, when the boiler are filled with questions. Boiler model selection is undoubtedly one of the most important and most difficult issues. If you choose a larger model will result in energy waste, increase business investment cost; use a smaller model afraid not enough normal business use, and gave enterprises to increase the problem.
Fans how conservation boiler inspection and maintenance service life longer insist on boiler fans periodic overhaul, maintenance of strict quality control. The elimination before the accident hidden danger in the bud, to overhaul a comprehensive, thorough, carefully check the wear, the impeller shaft and impeller balanced operation, with or without internal connections loose, collision, inlet baffle switch is flexible and bearing lubrication and cooling Happening. Take flue gas dust removal measures, regular cleaning flue boiler fans to improve the working environment. Dust removal equipment units to strengthen the dust removal operation and management, improve the efficiency of dust removal; no dust removal equipment units to time quantitative dosing into the boiler furnace special cleaning agents, and timely removal of fouling of the flue, the flue avoid clogging, the impeller damage accidents. Strengthen the operation and management, ban illegal operation. Boiler fan up and running, there must be strict rules. The induced draft fan starts to be unloaded, non-load starting, particularly when the boiler stoked, flue gas temperature is too low, such as with a load induced draft fan started, the starting current will increase much, and the start time is too long, fan motor overheat, overload is likely to burn out. Young fire in the boiler is running, pay attention drum, induced draft fan opening sequence, can not be reversed. I.e., first open fan, run for 10 minutes, and to exclude the furnace flue fouling or flammable gases, before the blower starts. If the first open blower, the induced draft fan, so that both the induced draft fan load is increased, so that the induced draft fan motor overheating burned, and the furnace may lead to explosion. Of the impeller blade surface hardening treatment to improve the wear resistance of the blade. Since the large fan boiler drawing high temperature flue gas fed is around 200 ℃, the flue gas contains large amounts of fly ash, SO2 and other corrosive gases, badly worn fan blades, fan output prone to drop, vibration, such as rupture of the blade. Therefore, to deal with a serious face or wear parts of welding blades to improve the wear resistance of the blade. Use DC welder welding, arc welding using manual method using a dedicated fan hardfacing strip (e.g., wear No. 1, Mo-Cr-B carbide electrode wear, etc.), and the electrode wear in 300 ~ 350 ℃ drying 1 hour use. Before welding, the surface of the blade should be fouling, rust cleaned, preheated to 100 deg.] C, with a small current, low voltage, temperature and speed, short arc welding symmetry. Practice has proved that, after surfacing treated leaves, wear resistance greatly improved, not only changed the fan impeller often wear, but also laid a good foundation for the safe operation of the fan.
hot-water boilers always have two such devices a primary and a secondary low-water fuel cutoff. They should be attached to the boiler through separate openings to prevent a striction in the connecting piping from disabling both devices. Many jurisdictions require re two such devices on steam boilers.Online chat
