Biomass Boiler - an overview | ScienceDirect Topics

The temperature where 70 wt% of the deposit is in a molten state and 30 wt% is in a solid state is called T70 or the flow temperature. Biomass boiler dusts tend to stick to the heat transfer surfaces and form hard deposits when they are between T15 and T70. An example showing the effect of water content on material behaviour is plaster.

High Pressure Boilers: Features and Advantages ~ ME

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
