1. The east-west span of the closed prefab steel coal storage shed is 105 meters, and the north-south length is 321 meters respectively;
The new construction and open-air renovation projects of the power plant use a fully enclosed environmental protection coal yard, which can be designed as a strip-shaped enclosed coal yard or a circular enclosed coal yard dry coal shed. The dry coal shed of Huadian Group Power Plant, that is, the closed steel structure of the strip coal yard, has a span of 105 meters;
2. The roof of the environmental protection prefab steel coal storage yard adopts a large-span steel structure space frame, designed coal storage capacity of 250,000 tons.
3. 100% dust suppression has been achieved after the fully enclosed structure coal warehouse is put into use. It is estimated that nearly 900 tons of coal dust can be reduced every year.
4. The space frame structure of the closed coal warehouse shed system in the coal yard is scientific and reasonable, and has been operating reliably for 20 years, meeting the coal storage requirements of the power plant;
5. The long-span steel structure space frame structure has been stable for 50 years and has passed inspection. Within a span of 100 meters, steel can be saved, construction costs can be reduced, and investment can be saved. Recycling steel when scrapped, increasing efficiency by 50-60%,
