6, red tube

Gas boiler for the purpose of using the punch tube boiler generated steam superheater flushing, rust, weld slag, iron, grime, and grease and other debris in the heat pipe and the heating surface of the steam pipe, when the steam supplied to the turbine or will cause harm, the former red tube boiler should have the conditions of the official launch. So red boiler tube boiler is the first time the entire boot process itself, it played a test equipment, inspection equipment, the initial grasp of the role of the operating characteristics of the device, the device successfully laid the foundation for the test run.

Steam boilers preventive measures to introduce a common fault with china dzl steam boiler and steam reciprocating pump preventive measures and to approach 1, steam boiler room near the venue to be equipped with adequate and effective fire-fighting equipment. 2, steam boiler room must have staff on duty 24 hours, the guards take turns, always check the water level in the boiler, ensure more safety line, to prevent dry cause an explosion.
