The waste heat recovery of flue gas can not only be used for heating or power generation to achieve energy-saving effect, but also can be beneficial to environmental protection and achieve dual effects of energy conservation and environmental protection. Hebei Fully automatic steam generator In general, the important equipment of waste heat power generation is waste heat boiler, which mainly uses heat or combustible substances in waste gas, waste liquid and other working medium as heat source, and produces steam mainly for power generation. There are many ways to recover waste heat from flue gas of waste heat boiler. Generally, comprehensive utilization of waste heat is followed by direct utilization and indirect utilization. small-scale Fully automatic steam generator how much Generally speaking, if heat sources are needed in the process, the waste heat utilization is mainly comprehensive utilization. First, the heat source is recovered and fed back to the process for reuse. If there is any surplus, it can be used for power generation or as the heat source for central heating; If there is no surplus, it will be directly used instead of being used for power generation; If the process does not need more heat sources, then indirect use, mainly power generation or public heating.

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. Hebei 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. small-scale Fully automatic steam generator how much 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.

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. Hebei 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. small-scale Fully automatic steam generator how much 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.

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. Hebei 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. small-scale Fully automatic steam generator how much 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.

Enterprises that rely on coal for power generation are both traditional power enterprises and highly polluting enterprises. The industrial waste gas discharged by coal power generation enterprises has seriously polluted our living environment. Hebei Fully automatic steam generator As a result, the country has become more and more strict in the control of this industry, and how to use waste heat recycling power generation has become a topic of concern for many enterprises. Waste heat boiler can meet this demand of enterprises, so its application in coal mine power generation enterprises is more and more. small-scale Fully automatic steam generator how much Installing a waste heat recovery boiler on the exhaust pipe of the coal mine gas generator set, using the waste heat discharged by the coal mine gas generator set to generate steam for power generation, can not only turn waste into treasure to realize the secondary utilization of energy, achieve the goal of combining coal mine gas control with energy conservation and emission reduction, but also reduce environmental pollution, kill two birds with one stone.

The waste heat boiler has advantages in the subdivided industry and is the leading enterprise in the industry. The company's main products are various types of waste heat boilers, industrial boilers, power station boilers, nuclear power equipment and power station auxiliaries. It is a research, development, design and manufacturing base for waste heat boilers with large scale and complete varieties in China. Hebei Fully automatic steam generator Waste heat boiler is a typical energy-saving and emission reduction equipment. Its heat source can come from high-temperature flue gas waste heat, chemical reaction waste heat, combustible waste gas waste heat, and even can use high-temperature product waste heat. At present, the company has more than 20 series and more than 100 varieties of waste heat boiler products, which are widely used in steel, building materials, power, nonferrous metals, coking, chemical and other industries. small-scale Fully automatic steam generator how much In 2008, the company produced 272 sets of waste heat boilers of various types, with a total of 10268 steam tons, accounting for 34% of the comprehensive market share based on steam tons; According to the output value, the market share is 47%, ranking first in the waste heat boiler industry.
