The two-stage gasifier is a high-efficiency coal gasification equipment. Its basic structure mainly consists of two parts: a retort section and a gasification section.

       The carbonization section is located in the upper part of the furnace body. Its main function is to dry and low-temperature carbonization of the coal entering the furnace. During this process, volatile matter in the coal gradually precipitates, forming retort gas. This part of the gas is rich in tar and is the main component of the top gas.

       The gasification section is located at the lower part of the furnace body. Its main task is to react the semi-charred coal after carbonization with the gasification agent (such as air, steam) to generate gasification gas. Gasification gas is mainly composed of combustible gases such as carbon monoxide and hydrogen. It has a relatively high temperature and is the main source of bottom gas.

       also,Two-stage gas generatorIt is also equipped with auxiliary systems such as coal preparation, coal addition, ash removal and gasification agent preparation to ensure the smooth progress of the entire coal gasification process. These systems work together to enable this equipment to efficiently and stably produce gas that meets the requirements.

       To sum up, the basic structure of the two-stage gas generator is reasonable and efficient, and it can make full use of coal resources to produce high-quality gas to meet various industrial needs.
