The pressurized hot water boiler itself is a device with a certain pressure. If it is not operated in accordance with the safety regulations during operation, accidents are prone to occur, which may cause damage to the boiler. Therefore, all heating users who use pressurized hot water boilers must abide by the relevant regulations and implement the relevant procedures before operating. Zhengzhou Fangkuai Boiler Factory has summarized the following safety operation rules, hoping to help everyone.
1. Check the appearance and gas pressure of the pressurized hot water boiler
Before preparing to start the boiler, the boiler worker on duty must first perform a thorough inspection, including the appearance of the boiler, valves and connections, and then check the gas pressure. Make sure the pressure is within the normal range, not too high or too low. Check before opening the air supply valve.
2. Check the water supply system of pressurized hot water boiler
There should be water inside the boiler when it is burning, otherwise it will be dangerous. The fireman should check the water supply system, you can see the water pump, if it is not a normal water discharge valve, it will open the air, know that the water pump can be started, and then open the water supply system for each valve.
3. Check the water level data of the pressurized hot water boiler
If too much or too little water in the booster boiler 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 operator know how much water is in the boiler at any time. Therefore, before starting the boiler, it is necessary to check whether the position of the water level gauge is normal, but also whether the water level gauge and the water level gauge color plug are in the open position to avoid false water level, and then observe whether there is water shortage.






We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
