Matters needing attention in the operation of hot water gas boiler system
Hot water gas boiler operation matters needing attention
(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 too fast starting pressure. After the boiler is in normal operation, the main water valve should be opened and the bypass valve should be closed.
(2) As the water temperature rises and make-up water enters the boiler, the gas will continue to precipitate, and the exhaust valve should be opened frequently.
(3) The hot water gas boiler should also be discharged regularly through the drain valve during operation. Pay attention to the stability of the pressure in the boiler during discharge to avoid water hammer accidents caused by evaporation of boiler water. The network system discharges sewage through the sewage processor.
(4) Minimize the amount of water replenished by the hot water heating system, repair water leaks in time, strengthen the management of exhaust and drainage devices, and prohibit random discharge of hot water for other purposes. Under normal circumstances, the water supply of the system should be controlled within 1% of the circulating water volume of the system.
(5) The expansion pipe of the expansion water tank should be installed on the main pipe of the boiler water supply (outlet). It is strictly forbidden to install valves on the expansion pipe and take anti-freezing measures.
(6) The circulating water should maintain a certain flow rate and flow evenly into each heating surface to prevent evaporation.
(7) Appropriate power failure protection measures shall be taken. When the natural circulation of hot water gas boiler suddenly power failure, can still keep the pot water continue to circulate, the safe operation of the threat is not big. However, when the forced circulation hot water gas boiler suddenly loses power and forces the water pump fan to stop running, the boiler water circulation stops immediately, which is prone to serious accidents due to evaporation. Some larger boiler rooms are equipped with backup power or diesel engines. When the power grid is cut off, it should be started quickly to ensure that the water circulation in the system will not be interrupted.
(8) In order to make the boiler burning system and water circulation system operate in coordination, to prevent accidents and expansion, it is best to the boiler coal ventilation and other equipment and water pump interlocking operation, so that the water circulation stops immediately after the furnace flameout.
(9) Now all over the promotion of environmental protection, especially gas boilers. When purchasing boilers, users should pay attention to local environmental protection requirements and choose the right boiler.
The above introduces the matters needing attention in 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 control the boiler within the normal range to ensure the safe and stable operation of the boiler.
