Gas turbines and gas engines are both efficient power generation solutions employed by many power plant operators. In manufacturing and other specialized industries, several manufacturers employ these types in various co-production CHP facilities. Textiles, food processing, petrochemical refining, medicines, electric utilities, and refining are just a few examples. Gas engines and gas turbines are the two principal power sources available to developers of distributed generating systems. Thousands of cogeneration combined heat and power (CHP) facilities throughout the world have proven both. Power utilities, hospitals, universities, district heating, seawater desalination, food processing, textiles, petrochemical refining, chemical processing, pharmaceuticals, pulp and paper, and general construction all use gas engines and turbines in CHP applications.
