Matters needing attention during the operation of a hot water gas boiler system

In industrial thermal applications, the hot water gas boiler operating system is relatively complex, including the boiler system and the piping system, as well as some situations that should be noted during the later operation of the hot water gas boiler system? Heze Boiler provides a detailed introduction:

 

Precautions for Hot Water Gas Boiler Operation

 

(1) When starting a large circulating water pump, the bypass valve should be opened first to prevent the boiler or radiator from being damaged due to excessive starting pressure. After the boiler is operating normally, the main water valve should be opened and the bypass valve closed.

 

(2) As the water temperature rises and the make-up water enters the boiler, gas will continuously precipitate, and the air vent valve should be opened frequently.

 

(3) During operation, the hot water gas boiler should also be regularly drained through the drain valve. When draining, pay attention to the stability of the boiler pressure to avoid water hammer accidents caused by boiler water evaporation. The network system drains wastewater through a wastewater treatment device.

 

(4) Minimize the make-up water of the hot water heating system, repair leaks in a timely manner, strengthen the management of air and water discharge devices, and prohibit the arbitrary release of hot water for other purposes. Generally, the make-up water of the system should be controlled within 1% of the circulating water volume of the system.

 



 

(5) The expansion pipe of the expansion tank should be installed on the boiler water supply (outlet) main pipe. Valves are strictly prohibited on the expansion pipe, and antifreeze measures should be taken.

 

(6) The circulating water should maintain a certain flow rate and evenly flow into each heating surface to prevent evaporation.

 

(7) Appropriate power failure protection measures should be taken. When a naturally circulating hot water gas boiler suddenly loses power, the boiler water can still continue to circulate, posing little threat to safe operation. However, when a forced circulation hot water gas boiler suddenly loses power and forces the water pump fan to stop running, the boiler water circulation stops immediately, easily causing serious accidents due to evaporation. Some larger boiler rooms are equipped with backup power supplies or diesel engines. When the power grid fails, they should be started quickly to ensure that the water circulation in the system is not interrupted.

 

(8) In order to coordinate the operation of the boiler burning system and the water circulation system and prevent accidents from occurring and expanding, it is best to interlock the boiler coal feeding and ventilation equipment with the water pump, so that the furnace will immediately extinguish after the water circulation stops.

 

(9) Nowadays, environmental protection is advocated everywhere, especially for gas boilers. When purchasing a boiler, users should pay attention to local environmental protection requirements and choose a suitable boiler.

 

The above introduces the precautions for the operation of the hot water boiler system. In fact, the safe and stable operation of steam boilers and hot water boilers is very important. The boiler owner should always keep the boiler within the normal range to ensure the safe and stable operation of the boiler.
