Numerical Methods applied for Power Plant Calculations
During the design of a power plant, the steam flow rates extracted from the turbine must be determined This is usually made by making the heat balance (heat in = heat out) and the mass balance (flow rate in = flow rate out) for the regenerative circuit The steam flow rates result from the balance equations, written for each heat exchanger apart
of cogeneration applications include pulp and paper mills, steel mills, food and chemical processing plants, and District Heating (DH) applications Since the beginning of the 20th century, cogeneration technology has been utilized by many industrial companies as an eco-friendly means to economically meet a plant’s combined heat and power .
