1, boiler room safety management system

Boiler room is one of the vital sectors of the use of the boiler unit, in addition to the boiler room workers, leaders and security production management personnel, other related personnel without the approval of the leadership will not be admitted.

The fully sealed membrane wall is widely used in modern boilers, and the expansion center is established. Therefore, around the boiler, there are many directional components above and below to ensure that the expansion center is the zero point and expand in a certain direction. Whatever does not bulge according to the design value, there must be residual stress, will be involved in the safety of support crane, must investigate its causes, in case of accident.
