1) the pressure rises sharply and exceeds the allowable working pressure. The pressure of the pressure gauge exceeds the allowable working "red line".

2) send out overpressure alarm signal, and the overpressure interlock protection device moves.

3) increase of steam temperature and decrease of steam flow.

Boiler such as Wood Treatment Equipment overpressure treatment:

1) rapidly reduce combustion and manually open the safety valve or steam relief valve.

2) increase the water supply, and at the same time, increase the discharge of the steam drum (at this time, attention should be paid to maintaining the normal water level of the boiler) to lower the boiler water temperature, thus reducing the steam drum pressure of the boiler.

3) if the safety valve fails or all the pressure gauges are damaged, the furnace shall be stopped immediately. The operation shall be boosted after the safety valve and pressure gauge are repaired.

4) when excessive pressure occurs in the boiler and endangers the safe operation, the pressure lowering measures shall be taken, but it is strictly forbidden to reduce the pressure too fast.
