The furnace structure of the gas generator can be divided into the following parts:

1. Shell: The shell is usually made of steel plates or bricks and is lined with refractory bricks to protect the internal structure of the furnace and maintain the temperature inside the furnace.

2. Coal adding device: Coal adding device usually adopts the form of intermittent coal adding hood, double material bell, vibrating coal feeder, gear tooth coal adding machine, etc.

3. Furnace structure:gas generatorThe furnace body structure includes different types of pressure full water jacket, semi-water jacket, waterless jacket (refractory material furnace lining), normal pressure full water jacket, etc., which can be selected according to needs.

4. Furnace grate: Furnace grate is usually in the form of pagoda type, steel welding type, etc., which is used to support the fuel and ensure that air and fuel are fully mixed.

5. Ash pan transmission structure: The ash pan transmission structure includes gear tooth type, worm gear type and other forms, which are used to drive the rotation of the ash pan.

In addition, the gasifier also has a carbonization layer and a drying layer, collectively called the coal preparation layer, and an oxidation layer and a reduction layer, collectively called the reaction layer. These structures are closely related to working principles.
