capacity also called power of a boiler. It is defined as the amount of water evaporated or steam produced in kg per hour. It may also be expressed in kg per kg of fuel burnt or kg/hr/m2 of heating surface. 2.1.1 Boiler Classifications Boilers are classified by their pressure capacity, their design type and by their use. High & Low Pressure
