grate firing的意思|示意

English word \"grate firing\" refers to a combustion technique that involves the use of multiple, closely spaced grates to break up the fuel and allow oxygen to mix with the fuel, increasing the rate of combustion.

It's a common way to burn coal and other fuels in industrial and power generation applications, as it makes it possible to control the rate of burning and get more consistent results.

Grate firing involves packing fuel onto metal grates which are closely spaced from one another. The grates are then placed inside a combustion chamber, where oxygen is introduced and distributed via a system of fans, pipes and other equipment.

With grate firing, air is pushed through the fuel on the grates, and the moving air helps to break up the fuel. This increases the surface area of the fuel that is exposed to oxygen, which speeds up the combustion process.

The fuel will continue to be broken up into smaller and smaller pieces as it burns, and the surface area of the fuel that is exposed to oxygen will also continue to increase. This means that the rate of combustion can be precisely controlled by adjusting the air flow and the fuel size.

Grate firing is a highly efficient combustion technique, as it maximizes the surface area of the fuel that is exposed to oxygen while ensuring that the fuel is constantly broken up into smaller pieces so that it can burn faster. Additionally, it is also a clean burning process, as the burning process can be precisely controlled, resulting in low levels of pollutants.
