1. Check the boiler appearance and gas pressure - when preparing to start up the gas-fired boiler, the stoker on duty should first do a comprehensive inspection, including the appearance of the boiler, valves and various connecting parts, and then check the gas pressure to ensure that the pressure value is within the normal range rather than too high or too low. After the inspection and confirmation, the gas supply can be opened Give the valve.
2. Check the water supply system - the gas-fired boiler should have water when it is burning, otherwise it will cause danger. Therefore, before starting the boiler, the stoker should check the water supply system to see if the water pump can supply water. If the water can not be supplied normally, the air release valve should be opened to vent until the water pump can start to fill water, and then open the valves in the water supply system.
3. Check water level - if there is too much or too little water in the gas-fired boiler, it will affect the safe operation of the boiler. It is very important to check the water level gauge before starting the boiler, because the function of the water level gauge is to let the fireman know how much water there is in the boiler at any time.
Therefore, before the start-up of the gas-fired boiler, it is necessary to check whether the position of the water level gauge is normal, and whether the level indicator and water level color plug are in the open position, so as to avoid the phenomenon of false water level, and then observe whether there is water shortage. The gas-fired boiler manufacturers who can meet the customers tell us that the above are the items that need to be checked before starting the gas boiler. In addition to these, the firemen should also check the wind deflector on the flue and ensure that they are all in the open state. Only by carefully checking all aspects of the boiler can the gas-fired boiler be officially started.
