  • boiler capacity--convert kcal/hr to ton/hr - Horizontal boiler

    The capacity of a steam boiler is often rated as boiler horse powers, tph, kcal/h, btu/hr and kW. We use different units to express boiler capacity. Tonnage and kcal are two common measurement units. The boiler is an energy conversion device. The energy input to the boiler is chemical energy and electric energy in the fuel.Learn More
