How Much Evaporation Does Large Boiler Mean

How Much Evaporation Does Large Boiler Mean

  • What is meant by high pressure boiler? | AnswersDrive

    A boiler with more passes has a higher heat extraction rate and is more efficient then one with less passes. Once a firetube boiler is started up and is operating at its desired pressure, a firetube boiler can handle a sudden upward load surge better than a watertube boiler because of the large steam disengaging area.

    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. Learn More
