A boiler rated at 9000kgs/hr with a designed working pressure of 10bar.g will have a maximum output of 8400kgs/hr with a feedwater temperature of 85 O C. The crown valve will have been sized on maximum capacity at 10bar.g and would typically be 150mm. 150mm pipe work is suitable for this load but by operating the boiler at 6bar.g would require 200mm pipe work if pipe velocity is kept reasonable.

Steam Boiler – Definition, Parts, Working, Types, …

This type of boiler works up to maximum pressure of 17.5 bar and steam capacity up to 10 kg/sec. The fire tube boiler has the advantage of lower initial cost, compact design, and easier operation. On the other hand, they have a risk of explosion, large water volume resulting in poor circulation, as well as more time is required for steam to reach the desired pressure.

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 F will be no more than about 220 F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building height.
