Why should natural gas boilers be shut down for maintenance

The membrane water wall of the boiler adopts fully welded structure, which has good sealing and no air leakage, reduces the excess air coefficient of flue gas and reduces the loss q2 of flue gas; The heavy refractory brick and red brick wall structure used in traditional industrial boilers is changed into light furnace wall, which has good heat preservation effect, heat dissipation loss q6 reduction, small heat storage of furnace wall and rapid start and stop of boiler.


The purpose of shutdown maintenance for natural gas fired boiler is to ensure that the boiler can operate durably under safe conditions, and to strengthen the protection and maintenance of the boiler during normal use. This is also the main measure to avoid a decrease in boiler thermal efficiency, deterioration in operating conditions, and boiler safety incidents.

1. In operation, scale and sludge may occur on the inner surface of a natural gas boiler, and incineration products may be attached to the outer surface of the fireworks tube. This will corrode the boiler body, reduce thermal efficiency, and endanger the safe operation of the boiler. Therefore, it is necessary to strengthen boiler protection management, formulate inspection plans, and implement them.

2. Boiler shutdown and cleaning. Before stopping the boiler for inspection, clean all the inside and outside of the boiler.

(1) Internal cleaning operations can be performed using mechanical or chemical cleaning methods. When the scale is thick or strong, first use chemical cleaning method, and then use mechanical cleaning method. When selecting the chemical cleaning method, it is necessary to strictly comply with national regulations to avoid corrosion damage to the boiler caused by random washing. Chemical cleaning shall be carried out by professional units approved by relevant departments. The mechanical cleaning method is to use things such as a hammer to eradicate scale. Checking after cleaning the boiler is a major task. Ignoring this task may result in incidents during operation, so it should be taken seriously.
