1, first of all, when the Miura cross-flow boiler overpressure with overpressure interlock to increase the water supply, at the same time in the lower steam package to strengthen the sewage (at this time, attention should be paid to maintain the normal boiler water level), in order to reduce the temperature of the pot of water to reduce the boiler steam package pressure.

2, second, when the Miura through-flow boiler overpressure with overpressure interlock to increase the water supply, while in the lower steam bag to strengthen the sewage (at this time, attention should be paid to maintaining the boiler's normal water level), in order to reduce the temperature of the pot water, thereby reducing the boiler ladle pressure.
