Energy balance calculation is often done for designing a heat exchanger to determine operating parameters for hot and cold fluids such as - inlet / outlet temperatures and flow rates. For hot fluid side of a heat exchanger let, m H: mass flow rate of the hot fluid in kg/hr Cp H: mass heat capacity of the hot fluid in Joules/kg 0 C
The program helps to make heat- mass balance of steam boiler such as the feed-water part, steam part and blow-down part. In addition, it is possible to calculate quickly for various pull-in conditions (boundary conditions).
Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler.
