2014/10/15 · The conventional model. We first formulate the conventional model, which is significantly less complicated than the cogeneration model. The first step is the capacity planning. The maximal steam production rate L is given, such that a boiler conversion cost Ω is incurred per unit.Get Price
Combined heat and power (CHP) is the simultaneous cogeneration of electricity and heat. Cogeneration is a highly efficient form of energy conversion and using gas engines it can achieve primary energy savings of approximately 40% compared to the separate purchase of electricity from the electricity grid and gas for use in a boiler.
