Steam Boiler Systems: What Every Project Engineer Should Know

Fire-tube boilers offer a compact and economical design for lower steam production rates. A fire-tube boiler will be the only choice for processes needing 300 Hp capacity or less. While every situation needs to be evaluated on it's own merits, a fire-tube boiler is usually the most economical for 1,200 Hp or less, however units are available up to 2,200 Hp.

Water for the Boiler - Spirax Sarco | First for Steam Solutions

2020/4/6 · In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.

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.
