Safety Operation Regulations for Gas-fired Boilers
Inspection of gas boiler before ignition: 1. Boiler, fan and boiler circulating water pump should be in good working condition.. Safety accessories (such as pressure gauge, water level gauge, boiler explosion door, etc.) should be complete, flexible and reliable.. The water level of the hot water tank is higher than 2/3 of the height of the tank (but lower than the overflow port). Boiler water level is full.. Keep the flue clear and open the air door of the induced draft fan.. Check whether the natural gas supply system can work normally (whether the air pressure is normal, whether the gas-liquid separator is empty), open the gas manual valve, and there is no leakage. Gas boiler ignition start: 1. start boiler induced draft fan, ventilation for 20 minutes.. Press the start button to start the burner nozzle. Step 1: Blow the stove for 5 minutes. After 5 minutes, it will automatically ignite. Observe whether the ignition is successful. After success, first run at low fire for one minute, then automatically turn to high fire, and then start the induced draft fan to run normally. (Automatic program) 3. During the operation, it should be checked regularly, once every half an hour, the main check points: a. Whether the natural gas flow and pressure are stable. B. Whether the motor burner is operating normally and whether there is noise in the motor. C. furnace flame is normal? d. boiler hot water circulating pump is normal (manual test). e. Whether the boiler pressure is normal (normal pressure, adjustment range: high ceasefire, low start). F. Whether the induced draft fan is normal and whether the motor makes abnormal sound. 4. During normal operation, the burner does not need any operation, and all large and small fire conversions will be performed automatically according to the setting needs.. The burner has the function of manually turning high fire and turning small fire button, and the heat can be manually controlled according to needs. (Start and stop 2# fire switch) Stop the gas boiler: 1. The furnace starts and stops regularly according to the production requirements.. Press the stop button to stop the burner and close the pipeline air supply valve.
