The two-stage gas generator is a good energy equipment, and its coal adding system is a key link to ensure its stable operation. The system consists of a hydraulic station and a coal discharge valve, which is responsible for adding coal evenly into the furnace to maintain the combustion reaction in the furnace.

The working process of the coal adding system is roughly as follows:

1. The hydraulic station provides power to drive the coal valve to open;

2. Control the amount of coal through the metering device so that the appropriate amount of coal falls into the furnace;

3. Close the coal feeding valve and wait for the next coal adding cycle.

This process can be carried out manually or automatically according to the needs of the furnace body to ensure that the furnace body is always in good working condition.

The stability and accuracy of the coal adding system directly affect the thermal efficiency and gas quality of the two-stage gasifier. If too much or too little coal is added, it will cause abnormal temperature and pressure in the furnace and affect the yield and composition of gas. Therefore, maintenance and adjustment of the coal feeding system are important.

In addition to the stoking system, the two-stage gasifier also includes other important components and parameters. For example, the retorting section and the gasification section are the main parts of the furnace, and their design and operating parameters determine the yield and composition of the coal gas. In addition, the carbon content of ash and temperature control are also important factors affecting the performance of the furnace.
