In a 600MW power plant,a supercritical combined-circulation boiler,with double-in-double-out ball pulverizing mill and positive-pressure direct-fired pulverizing system,has exploded many times since it is put into operation,imperiling to the safety and stability of the boiler.

With the development of explosion protection electrical technology,it is necessary to adopt of pressurized control system in the Ex equipment with a pressurized enclosure.
