Let’s talk about the dangers of gas counterflow in two-stage gas generators?
       Converting coal into natural gas for people's life and use not only converts the pollution caused by the direct combustion of traditional coal into clean energy, but also increases energy utilization and saves energy. However, gas is dangerous during the production process, and gas backflow has a great impact on the gas generator.
       When the air duct connected to the two sections of the gas generator is in normal operation, gas will not flow back into the air duct. However, if the blower does not work properly due to a sudden power outage or other reasons, and the check valve does not work, the gas may return to the blower box from the bottom of the gas generator and at the same time due to the higher gas temperature in the air duct. Air mixing may cause accidents. So how can we prevent this danger from happening?
       1. Ensure the check valves of the two-stage gas generator are securely sealed.
       2. After a power outage, the amount of steam delivered to the furnace must be increased in time to maintain positive pressure in the furnace.
       3. After a power outage, the air valve should be closed quickly and the channel for air entering the furnace should be cut off to prevent air from entering the furnace and causing an accident.
       4. According to the pressure at the gas outlet, pull the open valve to reduce the pressure in the furnace to prevent gas from flowing back to the blower.
       5. After the call is over, the gas in the air main pipe must be purged with steam before it can return to normal operation.
