Gas steam generator is also called gas steam boiler. The steam temperature is not high when the steam gas and steam generator has a fault. How can we solve this problem. Shanxi Fully automatic steam generator Generally, there are two situations: physical characteristics of water vapor: it will evaporate when reaching 100 ℃, and it is impossible for steam to reach a higher temperature. Although the measured temperature of steam is higher when it receives pressure, the temperature will drop to 100 ℃ as soon as it reaches normal atmospheric pressure. vertical Fully automatic steam generator manufactor The way not to imagine that the pressure of the steam engine will rise is to make the steam negative pressure. Every increase of about 1kg in steam pressure will increase the steam temperature by about 10 ℃, so by analogy, you need to increase the pressure as much as you need the temperature. I hope it is useful to you.

System oil drainage: circulate the heat transfer oil between 120 ± 5 to drain the heat transfer oil in the system (if you do not replace the oil, please find a clean container to store it properly). Prepare an appropriate amount of coke removal cleaning agent for the heat transfer oil system, drain the oil in the gas-fired heat transfer oil boiler system, and disconnect the cleaning system from the oil storage tank (close the valve), including the connection between the high-level tank and the oil storage tank. Shanxi Fully automatic steam generator Residual oil blowing steps: connect the air compressor at the pressure gauge or other places that can be connected, boost the system to 0.3-0.4MPa, and discharge it instantaneously; Repeat this process until the residual oil is blown out. The gas-fired heat transfer oil boiler, circulating pump, and other heat users form a cleaning circulating circuit for decoking and cleaning: add diluted cleaning agent to the system and fill it up to 1/2 of the water level of the high-level tank. Dosage of coke removal cleaning agent: 10~20%, the specific dosage shall be determined according to the scale thickness. Temperature: 90-95, time: 12-72 hours, which can be determined according to the scale thickness. Rinsing and cleaning: after cleaning, drain the residual liquid in the system and add clean water to rinse twice until the coke remover is free of foam and the water is clear. vertical Fully automatic steam generator manufactor Temperature: 85-95, time: 5-8 hours Water blowing steps: after cleaning, connect the air compressor at the pressure gauge or other places that can be connected, use compressed air to boost the system to 0.3-0.4 MPa, and vent at each low point. Repeat this process until the water is blown out. Waste liquid treatment: the cleaning waste liquid generated in the cleaning process is discharged after being treated in the biochemical tank.

Waste heat boilers are widely used in high energy consumption industries. There are two common types of waste heat boilers: one is used to recover the exhaust gas emitted by ordinary boilers, such as fuel fired and gas-fired boilers, biomass fired boilers, etc. The temperature of the exhaust gas from ordinary boilers is about 600 ℃, which is not too high, Therefore, the requirements for waste heat recovery boiler are relatively low. Shanxi Fully automatic steam generator The other is industrial waste heat recovery boiler, such as building materials industry, chemical industry, steel making industry, etc. The temperature of waste gas and waste heat in these industries is high, and the recovery and utilization are also quite valuable. vertical Fully automatic steam generator manufactor Henan Yuji Boiler Vessel Manufacturing Co., Ltd., founded in 2005, is located at No. 8, Jizhong Road, Xiaoji Town, Xinxiang County, Henan Province. It is a comprehensive enterprise of boiler and pressure vessel, mainly engaged in the manufacturing of boilers and pressure vessels, with technological innovation as the core, integrating the design, manufacturing, sales, installation, transformation and maintenance of boilers and pressure vessels.

Stainless steel for pressure vessels and its welding characteristics. The so-called stainless steel refers to the addition of a certain amount of chromium in the steel to keep the steel in a passive state and free from rust. Shanxi Fully automatic steam generator For this purpose, the chromium content must be more than 12%. In order to improve the passivity of steel, it is often necessary to add nickel, molybdenum and other elements that can passivate steel into stainless steel. Stainless steel is generally referred to as stainless steel and acid resistant steel. Stainless steel companies do not have certain acid resistance, and acid resistant steel generally has a good stainless property. vertical Fully automatic steam generator manufactor According to its steel structure, stainless steel can be divided into four categories, namely, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and austenitic ferritic duplex stainless steel.

Effectively prevent and reduce low temperature corrosion of air preheater. Low temperature corrosion is caused by sulfur dioxide generated by combustion of sulfur in fuel. Shanxi Fully automatic steam generator Under the action of catalyst, sulfur dioxide is further oxidized to sulfur trioxide. Sulfur trioxide and water vapor in the flue gas generate sulfuric acid vapor, which greatly increases the dew point of the flue gas, condenses the sulfuric acid vapor on the flue gas side of the preheater tube wall, causing sulfuric acid corrosion of the preheater. The content of sulfur trioxide has a great impact on the corrosion rate of the preheater. The content of sulfur trioxide is not only related to the sulfur content in the fuel, but also related to the oxygen content in the flue gas. vertical Fully automatic steam generator manufactor Low oxygen combustion can significantly reduce the oxygen content in flue gas, greatly reduce the amount of sulfur dioxide oxidized to sulfur trioxide, reduce the dew point of flue gas, and effectively reduce the corrosion of preheater. Low oxygen combustion reduces the amount of flue gas. It can not only reduce the exhaust gas temperature, improve the boiler efficiency, but also reduce the power consumption of the forced draft fan and the wear of the heating surface.
