Boiler Capacities - Engineering ToolBox

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

Exhaust vapours during deaeration. So the gases such as oxygen and CO2 dissolved in the make-up water and oxygenic condensate can also be removed from the deaerator, a proportion of roughly 0.5% of the mass flow rate consisting of make-up water and oxygenic condensate must be discharged as exhaust vapours to the atmosphere.
