What Is The Purpose Of Analyzing The Boiler Grate?

A grate is the part of a boiler that accumulates solid fuel and allows it to burn efficiently. It consists of two parts, the grate frame and the grate piece, usually cast in cast iron. After the assembly is completed, there should be a ventilation gap between each piece. A separate ventilation room with adjustable air volume is usually set under the grate, so that the air can enter the fuel layer through the gap, and the burnt ash can be discharged manually or mechanically. What are rows for?
1. The boiler grate is a horizontal three-pass water-fire tube hybrid boiler with a bundle of threaded smoke pipes inside the boiler drum. The left and right sides of the furnace are equipped with light tube water cooling walls. The light chain grate is used to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper slag scraper to realize automatic slag discharge.
2. The front and rear arches of the boiler grate adopt new energy-saving technologies. After the fuel falls from the coal scuttle to the grate and enters the furnace for combustion, the flame is refracted by the rear arch, upwards through the combustion chambers on both sides of the main body to the front smoke box, and then back to the inner tube bundle of the boiler through the front smoke box, and enters the coal-saving furnace through the rear smoke box. The device is then drawn by the induced draft fan through the flue to the chimney and discharged into the atmosphere.
3. Boiler grates can be classified according to different methods. Boilers can be divided into industrial boilers, power station boilers, marine boilers and locomotive boilers according to their uses. According to the outlet pressure of the boiler grate, it can be divided into low pressure, medium pressure, high pressure, ultra high pressure, subcritical pressure and supercritical pressure boilers.
4. According to the circulation mode, it can be divided into natural circulation boilers, auxiliary circulation boilers, once-through boilers and compound circulation boilers. Boilers are divided into chamber-fired furnaces, layer-fired furnaces and fluidized bed furnaces according to their combustion methods.
