Understand the function of the fire detection hole on the gas generator.
With the implementation of national environmental protection policies, the application of gas generators has gradually become more common. In its use, the application of its components is very critical. For example, the fire detection holes on the gas generators can reduce the occurrence of equipment failures. Next, let’s understand the role of the fire detection holes. The reasons why fire detection holes cannot be sealed and their solutions are as follows:
1. If the air seal gap of the fire detection hole is too large or too small, the fire detection hole will not be sealed. The air seal gap of the fire detection hole should be adjusted to about 1 mm.
2. When the air seal gap of the fire detection hole is blocked by tar and dust, the fire detection hole may not be sealed. Treatment methods: First, cover the fire detection hole, increase the steam pressure and turn on the steam, and purge for a period of time; second, if steam purging cannot solve the problem, the fire detection hole can be replaced under operating conditions; third, the fire detection hole should be regularly steam purged to prevent tar from condensing and blocking the air seal gap.
3. When the gas pressure in the gas generator furnace is high and the steam pressure is insufficient, the fire detection hole will not be sealed. This can be solved by appropriately reducing the gas pressure in the furnace and trying to increase the steam pressure to 0.2-0.4 MPa.

Therefore, it is necessary to always pay attention to the operation of the equipment to avoid clogging. At the same time, regular maintenance and repairs are very important to maintain the normal operation of the equipment during use.
