gas fired steam boiler maintain details
The processing of feedwater must be qualified,which is important issue to extend the service life and ensure the safety operation of gas steam boiler.

The temperature of feedwater should be close to the furnace’s, preferably above 20 ℃.

The low water cut-off devices must be checked,cleaned and maintained regularly.The water level controller must be cleaned at least once a month,while, the water level indicator should be washed at least once a day.The water level indicator should be washed at the highest water level,the water level should not be below the lowest safe waterline after rinsing,it can be cleaned repeatedly.

The regular operation of pollution discharge is needed,at least once a day(class),after the pollution discharge,we should check that whether the blow-down valve has the leakage,it must be excluded if it has the phenomenon.

When the furnace was stopped without maintaining the pressure of steam,the steam space of the boiler will produce negative pressure and has air entrapment,so,the total steam valve should be opened first when we begin to ignite again.

The fouling of smoke tube leads to the rise of the exhaust temperature, so that the efficiency of gas steam boiler will reduce.Therefore,the cover of front and rear door should be opened regularly to brush or blow the fouling of smoke tube

Burner maintenance:
No matter boiler body maintenance or boiler burner maintenance, it should be processed by professional staffs. The best maintenance time is after heating period instead of maintaining at the beginning of heating period. Besides, combustion may produce something especially sulfur will corrode the boiler, so do not let the combustion products stay in boiler for long time.

Blowdown: Boiler bottom blowdown is very important for preventing the flue gas condensation. Flue gas condensation is due to the water containing in smoke (diesel or natural gas) and too low flue gas temperature.
