Anqing Petrochemical coal gasification plant achieves smooth operation for 60 days
According to the production and processing methods can be divided into the following categories: Galvanzied Steel Sheet, Gi Plate, Galvanized Plate,Galvanised Steel Plate,Galvanised Plate Shandong Longhao Steel Group Co., Ltd. , https://www.longhaosteels.com
Shell coal gasification has the characteristics of wide adaptability of coal, high coal conversion rate, and clean and environmental protection. The practice and application of Shell coal gasification have attracted the attention of all parties. As Shell coal gasification technology is used in large-scale fertilizer production, Chinese companies have taken the lead in trials. The immature part of its engineering needs to be gradually improved. Frequent fluctuations in the operating parameters of the equipment before the addition and serious wear of some equipment have brought varying degrees of difficulty to continuous operation. To this end, Anqing Petrochemical specializes in establishing a fast-responsive paramedics team. Engineers, technicians, and first-line operators are soaked at the site all day long to use their brains to find ways. Gasification furnaces require a particularly high level of cleanliness. Large cinders can easily cause pipeline blockage. Anqing Petrochemical specially installed two fiber separators at key locations to ensure smooth pipelines. Due to the different batches of coal raw materials, the impurities contained are also more or less. For large cinders, large fibers and other impurities, they sent someone to clean coal in the coal warehouse to clean coal. They also stepped up inspections of key equipment and organized special protection for the actual conditions of the operation of the gasification unit's pumps. In response to the problems existing in the gasification burners and ash removal and ash removal systems, technical rectification was undertaken, and personnel were responsible to ensure All-weather escort. Under abnormal conditions, the operator changed the automatic operation to manual in a timely manner. According to the operating status of the device, the production load was quickly adjusted so that the oxygen-to-coal ratio of the device was in the best condition, ensuring smooth operation of the device.
â‘ Hot dip Galvanized Steel plate. The sheet steel is dipped into the melted zinc tank so that the surface is adhered to a zinc sheet steel. At present, continuous galvanizing process is mainly used to produce, that is, continuous immersion of rolled steel plate in the melting of zinc in the plating tank to make galvanized steel plate;
② alloyed galvanized steel plate. This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to produce a zinc and iron alloy film. This galvanized sheet has good coating tightness and weldability;
â‘¢ Electric galvanized steel plate. The galvanized steel plate made by electroplating has good workability. But the coating is thin, corrosion resistance is not as good as hot dip galvanized sheet;
â‘£ Single-side plating and double-side difference galvanized steel plate. Single-sided galvanized steel plate, that is, galvanized products only on one side. It has better adaptability than double-sided galvanized sheet in welding, coating, rust prevention and processing. In order to overcome the shortcomings of single side without zinc coating, there is a galvanized sheet coated with a thin layer of zinc on the other side, namely double-sided differential galvanized sheet;
⑤ Alloy, composite galvanized steel plate. It is made of zinc and other metals such as aluminum, lead, zinc alloy and composite plating of steel plate. The steel plate not only has excellent anti-rust performance, but also has good coating performance;
In addition to the above five kinds, there are color galvanized steel plate, printing coated galvanized steel plate, PVC laminated galvanized steel plate and so on. But at present the most commonly used is still hot dip galvanized sheet.
