Feb 11, 2018 · I have to design a model of a domestic boiler. I represent the boiler as a heat exchanger (HEX1), as shown in the figure. In many articles I have found that it is schematized with this equation: M C dT 10 dt = c m _ dot ( Ti − T 10) − Q. where M C is the thermal capacity of the boiler, and Q is the heat product by the burner.Get Price
District Heating (DH) is a rational option that is adapted to provide domestic heat and hot tap water to buildings, particularly in densely populated areas. The main idea of district heating is to substitute local heat generation, which is usually obtained using domestic boilers, with centralized heat production.Get Price
