b. Energy analysis of boiler drum (i.e. heat exchanger) The boiler is considered as a single cross-flow steam pro-duction chamber. The performance of the steam produc-tion chamber plays an important role of the boiler efficien-cy. Heat is transferred from the hot fluid to the cold one through the wall separating them. Heat exchanger is a de-
Heat balance. An application of the first law of thermodynamics to a process in which any work terms are negligible. For a closed system, one that always consists of the same material, the first law is Q + W = ΔE, where Q is the heat supplied to the system, W is the work done on the system, and ΔE is the increase in energy of the material forming the system.
