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. Guizhou Oil fired gas 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. vertical Oil fired gas 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.
The existing industrial boiler flue gas waste heat recovery equipment mainly includes tubular heat exchanger and full heat pipe heat exchanger. Tube and tube heat exchanger can be composed of finned tube bundles. The advantage of finned tube is that it can withstand higher temperature, but has low heat transfer coefficient and large floor area. Guizhou Oil fired gas steam generator The flue gas of industrial boilers contains sulfur and other acidic substances. In the low temperature zone (flue gas outlet section), the temperature may be lower than the dew point of the acidic substances. The acidic substances will dew on the pipe wall, corrode the shell of the fin tube. The fin tube heat exchanger has poor operating reliability and low service life. vertical Oil fired gas steam generator how much The total heat pipe heat exchanger of boiler flue gas waste heat recovery equipment is composed of heat pipe bundles. Its shell is made of multi-layer composite materials. The heat pipe structure is complex, the cost is relatively expensive, the service life is short, and the steel consumption is large. It is difficult for users to accept it, and it is difficult to promote its application in production. The composite heat pipe heater not only takes into account the heat exchange effect, but also takes into account the economic affordability of the investors in production, which is particularly suitable for the current situation in China's industrial production.
The main parts of the waste heat boiler can be divided into drum, pipe, header, membrane wall, tube panel, tube box, etc. These parts are the parts with specific process requirements in the waste heat boiler. Guizhou Oil fired gas steam generator For example, the drum should go through metal flaw detection, heat treatment, hydrostatic test and other processes to improve the stability of the waste heat boiler. At the same time, because the header needs high sealing, manual welding is required, and the welding quality needs to be tested. It can be seen that due to the complexity of the working environment of the waste heat boiler, it has special requirements for its internal structural members. vertical Oil fired gas steam generator how much In the process of designing and manufacturing the waste heat boiler, the process designer should consider the advantages and disadvantages of various processes, and then select a reasonable process to complete the manufacturing of the waste heat boiler. For example, the serpentine parts in the waste heat boiler cannot be bent automatically by the machine, so they can only be bent manually.
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 Oil fired gas 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 Oil fired gas 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.
You will find that the characteristics of industrial boiler equipment are obvious. When designing industrial boilers, they should be regularly maintained. Vertical boilers have obvious characteristics Guizhou Oil fired gas steam generator The combustion part adopts a double-layer grate combustion chamber, which has fast temperature rise and pressure rise, reasonable overall layout, good heat transfer, sufficient combustion, smoke suppression and dust removal for unburned gas after secondary combustion, and is one of the smaller steam and heating equipment. vertical Oil fired gas steam generator how much The characteristics of the whole industrial boiler are obvious, with high thermal efficiency and sufficient steam. The whole industrial boiler is equipped with excellent safety valve, pressure regulator, low water level and other multiple protection devices, which can effectively ensure the safe operation of the boiler. Moreover, industrial boiler equipment is compact in structure, small in floor area, elegant in shape and bright in color. Therefore, it plays an important role in many large factories and coal mining enterprises.
