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

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.

Effect of Lance Pressure on Sootblower Jet Characteristics

At any supply pressure other than the design pressure for a given nozzle, the resulting supersonic jet will be "off-design" because the jet pressure at the nozzle exit will be lower (over-expanded) or higher (under-expanded) than the ambient boiler pressure. Unlike a fully-expanded jet, off-design jets are characterized by a multi-cell shock
