What Causes High Pressure on Steam Boiler — Heating Help: The

Comments. The feed water can be heated to saturation of temperature in the economizer with the help of waste heat. Recovery from the exhaust gases is escaping to the chimney. Then the boiler supplies only latent heat of vaporization and superheat. Thus, a boiler operation at high pressure will require less heat addition for steam generation.

Effect of Low Steam Pressure Operation of Boiler

Low Steam Pressure in Boiler. Normally the turbine will slow down due to the braking effect of the generator. During this time the steam demand signal will go up reducing the pressure further if the fuel input does not increase. As the main steam pressure drops, there is a good reason for the auxiliary steam pressure to drop.
