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.
Read MoreDEHA has been successfully utilized to treat a variety of low pressure and high-pressure boiler systems replacing both hydrazine and sulfite as well as competitive organic oxygen scavengers. It can be used in any type of boiler system where the feedwater temperature exceeds 180°F under alkaline conditions (pH 8.5 or higher). However, DEHA does not

The first of Trevithick's high pressure engines, a steam whim working expansively at 172kN per sq m (25psi), was begun at Cook's Kitchen mine in 1800. It had a 480mm diameter cylinder with a 1.52m stroke and was still working in 1870. To cope with the higher pressure, he designed a wrought iron cylindrical boiler with internal "tube and fireplace".
