  • What Causes High Pressure on Steam Boiler — …

    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.

The steam pressure limit is based on the fact that when the steam pressure in the boiler rises, thicker fire tubes and chambers are needed – thus the price of the boiler rises. As a result of this, boiler types where water/steam mixture is

    2010-2-2 · Too much water in the expansion tank and too little air may also cause pressure to rise frequently. If the bottom of the tank does not feel hotter than the top, it indicates an excessive amount of water. You need to drain this water from the tank. To do so, first turn the boiler off. Then close the water shutoff valve and allow the system to cool.

  • How to Calculate Boiler Steam Flows Hunker

    Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.

    This is possible because the water-vapor pressure inside the confined boiler space increases correspondingly during the heating process. In normal boiler operation, the liquid water remains in the bottom part of the boiler due to gravity, while steam bubbles rise through the liquid water and are collected at the boiler top for use.
