During the use of the two-stage gas generator, you will find that sometimes it needs to be pressurized. By pressurizing, the furnace temperature can be increased and the efficiency of the equipment can be increased. Although it is a common operation to pressurize the bottom of the equipment, why is it necessary? Because this is related to the following reasons:

1. The material layer is too thick, which will increase the resistance and increase the pressure at the furnace bottom.

2. The details of the coal lumpiness. If the coal is too small or pulverized coal is put into the furnace, the resistance of the material layer increases, and the temperature of the furnace bottom will rise.

3. Severe slagging will cause the blast to be unable to pass through, and the gasification agent can only pass through the slag block side. At this time, the flow rate increases, the gas resistance increases, and the pressure at the bottom of the two-stage gas generating furnace increases.

4. The stronger the cohesiveness of the coal used, the greater the resistance of the material layer and the higher the pressure at the furnace bottom.

5. The greater the flow rate, the greater the material layer resistance will be, which will increase the pressure at the bottom of the furnace.

The requirement for a two-stage gas generator is to reduce the generation of resistance as much as possible. The purpose of furnace bottom pressurization is mainly to increase the overall efficiency of the equipment and increase the overall safety performance of the equipment.
