Problems solved by technology
[0002] In our country, the circulating fluidized bed boiler is developing rapidly, but the hot red slag material slag discharge valve of this furnace cannot meet the satisfactory requirements
Because the temperature of the hot red coal slag in the lower row of the circulating fluidized bed boiler is 850°C-900°C, and the standard particle size is within 15mm. At present, whether it is a motorized gate valve or a manual gate valve, it is a dry gate valve, and the dry gate valve Being stuck due to heat, unable to move and circulating fluidized bed boiler requires high temperature and uniform discharge of hot red slag is a big contradiction. Many manufacturers choose expensive alloy steel to produce gate valves, but there are still many deficiencies. For example, if the valve is made of expensive alloy steel, the cost is high, and the valve that discharges hot red slag will expand when heated for a long time. At the same time, due to the thermal expansion and displacement in the radial direction of the lower slag pipe of the circulating fluidized bed boiler, the high-cost stainless steel wave interface compensator is used, and the height is relatively large. Therefore, the cooling slag supporting the slag discharge The installation of the machine has a greater impact
