foam products natural gas atmospheric water tube boiler supplier
Oil-fired foam products atmospheric water tube boiler supplier technical analysis when equal sulfur content greater body oil and coal, low-temperature corrosion of boiler fuel in general is much more serious than a coal-fired boiler, for two main reasons: 1 coal-fired boilers, especially pulverized coal, coal 90% of the ash content of the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed fly ash in the flue gas, sulfuric acid vapor in the flue gas is reduced; coal combustion, about half of the sulfur remaining in the ash . While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content in the fuel, about 11% to 12%, per ton of fuel combustion can produce about one ton of water vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because with water and more exceptions detailed in Table 1 below. When these two reasons that the fuel, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to use of fuel oil-fired boiler, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, low-temperature corrosion is worse than boiler fuel fired boilers.
Steam foam products atmospheric water tube boiler suppliers common faults and submersible pumps fast boiler's Henan Xiao Bian introduce a common steam boiler failure problems common faults and submersible pumps steam boiler water level is with you, the causes and solutions to a steam boiler water level is a common problem its reasons: 1, the water level is too low installation; 2, water, a water pipe connected too small; 3 have a water level or a low level display instrument automatically when the water level on only one boiler; 4, drainage water gauge no grounding drain cock; 5, the drum water level is an effective, other water damage; 6, the tap water is screw fixed; 7, the tap water gauge leak, leaking; 8, water gauge false water level on a display; 9, the drum water level in the two water gauge level of inconsistency; water glass is often broken; 11, water glass is no guard; 12, the water level is low level indicating no glass panel represents red; 13, level glass plate is dirty, the water level observation is unclear. The main reason is because of 1-4 above design, installation or alteration of dislocation caused. When the steam boiler with a low water level status is when the drum water level is only one case, because the internal balancer lowland water's leakage short circuit (can not be detected at that time), causing lowland water level is high water level appears ( the so-called full of water), while the water level on the drum have shown that low water levels (and may even see the water level), then the fireman because they can not determine the true level of the boiler will go immediately and check the water level on the drum, it will be very serious water shortage delays container boiler accident occurred. Some even show the water level too low trust level's status, and take a lot of sewage, mistakenly steam boiler water when filled with water incident handling, acceleration accidents, there is precedent for such incidents to be investigated. Then, the above-mentioned reasons for the failure of 5-9 main problem is the boiler running for long periods of time rinse water, a daily maintenance is not carried out, resulting in water cock rust, gas, water and even the block, or insufficient packing or aging deterioration . False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water level due to misalignment connected; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the water level in the boiler and false priming. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water gauge is being cold draft at window glass, and glass pipe quality was poor. Submersible pump is a mechanical and electrical integration of high-tech products. In recent years, due to the submersible pump in a sealed, insulation, cooling and monitoring technologies have made great progress, but also successfully achieved the automatic coupling pumps and water pipes, so that the large diameter submersible pump application significantly faster. Since diving save electric pumping station project investment, quick installation and maintenance, operating conditions greatly improved equipment reliability and service life improved significantly. At present, China is not only the production and installation of large-diameter 900 mm below the axial and mixed-flow pump, can produce diameter 1.4 m and 1.6 m large submersible pumps, has laid a good foundation for the promotion of technical diving electric pump station. Gao dive afraid of flooding, but also has good maneuverability advantages of quick removal and installation, able to cope with the water level soared, chestnut room flooding and other emergencies pieces, large-scale changes asked of submersible pumps. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
How pressure hot water foam products atmospheric water tube boiler supplier the security work in Year 6 at night, is located opposite the old steam boiler certain aquaculture farm town of Rudong Ju Wang Tan explosion cause of the accident is operating a boiler operator improper. Such as shrimp farms in the South East of whitening, the use of the boiler is very extensive, mainly used for farming shrimp shed warming. Before many farms use steam boilers, higher risk, many farms put on a higher level of security pressure hot water boiler. Pressure hot water boiler is no risk, but it does not mean you can neglect of duty fireman. To regularly observe the water level to avoid low water level, the situation appears dry, otherwise there will be a certain risk, but will seriously reduce the life of the boiler using pressure hot water boiler. Boiler operator should note the following: 1, strict implementation of rules and regulations, seriously concerned to learn boiler expertise, and constantly improve the level, to ensure safe and economic operation of the boiler. 2, the pressure hot water boiler in use, organizations and individuals will be allowed to change the structure of the boiler, valves and piping system 3, before the predetermined succession visits to check a variety of devices, comprising: a water tank (hot water tank, expansion tank) , the amount of energy (boiler gas meter), a thermometer (temperature of hot water tank, the boiler water temperature of heat medium) and the like operation, when the shift operation to check the recorded inventory tool, and to learn more about the operation of the boiler. 4, take over staff as required, shift and provisions ahead of time to take over the boiler room to do the preparatory work, and to understand the operation of the boiler. 5, shift work were prepared in advance, be careful and comprehensive inspections and investigations, to keep the boiler running. 6, shift workers should take over personnel issues related to equipment operation, water quality and boiler blowdown, etc., without handing, transfer of personnel shall not leave their jobs. 7, keep the boiler running when the boiler clean, no dirt, no leakage, no rust and corrosion, carefully fill out detailed equipment maintenance records. 8, using the boiler room is one of the vital sectors of the boiler unit, in addition to the boiler room workers, leaders and security, defense, department managers, other unauthorized persons do not access inside. 9, prohibits storage of flammable boiler room and other debris and the like, loaded with a small amount of lubricant required, cleaning the oil drums, oiler, to be stored in designated locations, and pay attention to check whether the explosives combustion. 10, boiler room to be equipped with fire fighting equipment, carefully managed, it should not be moved or used for other purposes. 11, boiler room floors, walls, doors and windows keep clean. 12, competent leadership regularly, irregularly running records, sanitation inspection, identify problems and timely solutions. 13, at the stipulated time to work on time, do well shift recording, not just leave their jobs, leave something. 14, alcohol is strictly prohibited in the boiler room, drowsiness, gambling, fighting once found seriously. After 15, equipment failure and accidents timely reporting (timely reporting on duty the night the person in charge), realistic write a written accident report, to be thoroughly investigated, after clarifying the responsibility, resulting in losses to the accident negligence, be held accountable process.
