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. Guizhou 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 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.

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. Guizhou 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. vertical Steam generator manufactor 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.

As a large equipment, the maintenance of gas-fired hot blast stove is one of the things that must be done. Guizhou Steam generator Regular maintenance can not only keep the hot blast stove clean, but also improve the service life of the hot blast stove. Therefore, it is the top priority in the use of hot blast stove. Today's editor will tell you how to maintain the hot blast stove regularly. In many manufacturers that use hot blast stoves, in order to better develop the enterprise, it is necessary to increase the number of hot blast stoves and improve the performance of hot blast stoves. vertical Steam generator manufactor When enterprises purchase hot blast stove equipment, they must understand their own needs and the products of hot blast stove manufacturers in the market. Therefore, the small edition of gas-fired hot blast stove tells us the problems to be considered in the selection of hot blast stove.

As a pressure vessel, waste heat boiler shall be used reasonably and managed scientifically in the process of use to avoid safety accidents caused by improper use and management. The quality of water is one of the important factors affecting the service life and safe operation of waste heat boiler. The quality of water added into the boiler directly affects the normal operation of waste heat boiler. Guizhou Steam generator The normal delivery of water is the lifeblood of normal boiler use. If the boiler is short of water, it is bound to cause major safety accidents and fatal damage to the boiler. Therefore, it is necessary to ensure continuous and stable water transmission during boiler operation. vertical Steam generator manufactor Regardless of the tonnage of the waste heat boiler, the lower configuration of the boiler electric control shall ensure the continuous operation of the boiler water pump, and the water supply pipeline shall be equipped with a water supply regulating valve with good regulation characteristics to control the water supply flow according to the level of the boiler. In addition, in order to ensure that the normal delivery of water will not be affected by the pump failure, a standby pump should be ensured.

Most softened water equipment can only slow down the scale growth rate, but can not achieve the purpose of scale prevention. The water quality used by different users varies greatly in different regions. Guizhou Steam generator In some construction sites, steam generators are used for steam maintenance of bridges because tap water cannot be used due to conditions. Only groundwater or river water can be used. At present, the hardness of many groundwater in China exceeds the standard, and the total hardness of water in some areas is high. vertical Steam generator manufactor It can reach several hundred millimoles, which is quite serious. I think the use of water softener is basically ineffective, because ordinary resin exchange water softener can only affect water with hardness of 7, which also ensures the use process. It needs to be cured regularly.
