Special Section: Flow & Level: Boiler drum leve

2019-9-4 · Poor level control also has an effect on drum pressure control. The feedwater going into the drum is not as hot as the water in the drum. Adding feedwater too fast will result in a cooling effect in the boiler drum reducing drum pressure and causing boiler level shrinkage. This can be demonstrated by pouring tap water into a pan of boiling water.
