High Pressure Boiler: What is it? Types & Characteristics

It is a water tube, forced circulation boiler, where the feed water is compressed to supercritical pressure to prevent the formation of bubbles in the water tube. The compressed water feed increases the density of the water such that its density and that of the steam become the same, which reduces the latent heat in the water to zero making it easier to convert to steam.

However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs. To keep the same level of steam output at higher design pressures, the distance between the lower drum and the steam drum must be increased, or some means of forced circulation must be introduced.
