How to properly maintain the gas steam boiler when it is out of service?

Gas-fired steam boilers are the first choice for many industries such as food processing, paper making, brewing, and chemical production. In the current boiler market, gas-fired steam boiler technology has been very advanced, with obvious advantages of stable operation and low energy discharge and energy saving. If you do not use it for a long time, you must use the correct maintenance method to maintain normal operation during subsequent startups.

The gas steam boiler is not used, the specific maintenance method and the square boiler are carefully analyzed.

1. dry maintenance
       The gas-fired boiler needs to be drained after the furnace is shut down, then the internal dirt is completely removed and rinsed, and the drying in the furnace is kept so as not to be eroded.
       You can use a small fire when drying the remaining water in the furnace, but you should not use a large fire. Also be careful to close all the hand hole pipe valves and place the quicklime pan in the drum.
       If you have not used a gas steam boiler for a long time, check the boiler at least three months. If the quicklime in the crucible is broken into powder, it is necessary to replace the new lime in time to ensure that the dryness protection in the gas steam boiler is not corroded by moisture.

2. wet maintenance
       The specific operation procedure of the wet maintenance is: after the water in the furnace is discharged, the internal dirt is removed, and the treated water is filled into the crucible and then heated to the required temperature; then the gas in the water is completely discharged to the furnace. In addition, close all valves. However, it should be noted that when the weather is very cold, wet maintenance should not be used to prevent the furnace water from freezing and damaging the furnace and cannot be used.

It can be seen that the gas steam boiler can be used in both dry and wet methods without being used. The specific maintenance method should be flexibly selected according to different sites and climatic conditions, which is also for normal use in the future. "Protect the escort."
