COGEN is a common abbreviation to “Cogeneration” which means generation of heat, in the form of steam, and electric power. The cogeneration concept is considered as the most energy efficiency solution for process plants that requires both steam and power in normal operation. COGEN is composed of gas combustion turbine that consumes fuel to produce electric power via electric generator; the hot flue gases from the turbine are utilized to produce high pressure steam in a heat recovery steam generation (HRSG).
COGEN sizing can be optimized to deliver exactly the required power with maximum possible steam production, known as “Power Match”. It can also be sized to deliver the required steam flowrate with the maximum possible power generation, known as “Thermal Match”.
