Stainless steel grate for thermal power plant

Short Description:

Grate is a part of boiler or industrial furnace where solid fuel is stacked and effectively burned. The whole grate mainly includes two parts: frame and grate.

A grate is arranged in the steam boiler to support the solid fuel in the boiler. The grate is designed to also allow air to enter the solid fuel for combustion.

Horizontal tempering tube boilers are generally used in small capacity thermal power plants. It consists of a horizontal drum with many horizontal tubes. The pipes are submerged in water.

In order to generate electricity, power plants use high-pressure steam. Boilers obtain energy from some form of fuel, such as coal, natural gas or nuclear fuel, and heat water to steam.

Description

Power plants use boilers to produce high-pressure steam to generate electricity. This process is called the Rankine cycle. Boilers obtain energy from some form of fuel, such as coal, natural gas or nuclear fuel, and heat water to steam. In addition to a small part of the primary energy in the world comes from fuel, the remaining three-quarters of the fuel eventually goes into the boiler (the remaining fuel goes into the internal combustion engine, which uses different fuels).

The grate is usually made of casting. After assembling, the necessary ventilation gap is kept between the plates, and a separate ventilation chamber which can adjust the air volume is often set at the bottom of the grate, so that the air can enter the fuel layer for combustion through the gap.
