Boiler designs can be classiied in three main divisions – ire-tube boilers, water-tube boilers, and electric boilers. 9.2.2.1 Fire-Tube Boilers Fire-tube boilers rely on hot gases circulating through the boiler inside tubes that are submerged in water (Figure 9.2.1
Get a quoteHowever, 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.
