The selection of casting materials for Boiler Steam Boiler Grate Bars is very important. For the boiler accessories themselves, the material is very important for its performance and the length of its life. Next, I will briefly introduce the factors to consider in the selection of boiler accessories.
Brightness: The cast steel products are bright, the cast iron is dark and gray, the gray iron in the cast iron is different from the ductile iron, and the ductile iron is brighter than the gray iron. Particles: Very fine particles are generally invisible to the naked eye. Both gray iron and ductile iron can see particles, gray iron particles are larger. Movement and stillness: The collision of steel castings is "just", which is different from the movement and stillness of cast iron. Gas cutting: Boiler Steam Boiler Grate Barshas a rough surface, and the riser and gate area are large, so gas cutting is necessary to eradicate. Nodular cast iron gas cutting continuously. Resistance: The cast steel resistance factory is close to the steel plate, the ductile iron boiler parts are less resistant, the thin-walled parts can reach 20-30 degrees of bending, and the gray has no resistance.
In a thermal power plant, the function of the boiler is to use the heat energy released by the combustion of the fuel to generate high temperature and high pressure steam. The design and main components of the boiler body are designed to fulfill its function. The design of the boiler body includes furnace, horizontal flue and vertical flue (tail flue), the main Boiler Steam Boiler Grate Bars are set according to the combustion system and soda system, with air preheater, burner, economizer drum , downpipe, water wall, superheater, reheater, etc.
