Garbage incinerator grate operating principle in detail?

The garbage incinerator is a kind of municipal garbage and other waste through high temperature combustion processing equipment. Among them, the incinerator grate is a key component of the incinerator, also known as the grate or movable grate, is mainly responsible for the effective combustion of garbage and will produce heat transfer to the furnace wall and water cooling plate.

The principle of operation of a waste incinerator grate consists of the following steps:

1. Handling: First, the waste is transported to the waste incinerator and transferred to the grate by a handling system.

2. Uniform distribution: In order to ensure that the garbage on the grate can be fully combusted, the grate needs to be operated in such a way that the garbage is uniformly distributed over the entire grate, usually in a layer-by-layer stacking manner.

3. Preheating: The grate is then preheated to bring it up to a suitable temperature to prepare the waste for combustion.

4. Combustion: When the grate reaches the right temperature, the waste starts to burn. During the combustion process, the organic matter in the garbage is decomposed into water and carbon dioxide and other gases, and a large amount of heat energy is generated.

5. Heat transfer: The grate transfers heat to the furnace wall and water cooling plate through the long strip plate, thus effectively recovering the heat energy generated by the garbage combustion.

6. Ash cleaning: finally, the unburned garbage as well as the generated ash are cleaned out of the furnace for subsequent processing.

In general, the operation principle of the waste incinerator grate is similar to that of a normal furnace, except that it also needs to take into account the type of waste, moisture content and other factors, as well as how to control the emission of pollutants in the combustion process.
