Heat and Power (CHP), or cogeneration, provides both an on-site source of
electric power and useful energy from a single fuel source. These systems
capture thermal energy that would normally be lost in traditional power
generation and use it to serve on-site heating and cooling needs.
form of distributed generation, CHP systems typically are located at or near
the energy-consuming facility. Recovering the heat normally lost in power
generation or transmission processes to provide on-site heating or cooling
results in increased energy-efficiency and reduced greenhouse gas emissions.
systems are configured with either a topping or bottoming cycle. In a typical
topping cycle system, fuel is combusted in a prime mover -- such as a gas
turbine or reciprocating engine -- to generate electricity. Most energy lost
from the prime mover’s hot exhaust and cooling systems is recovered and
provides valuable and usable heated air or water. The heated air is
generally used for industrial processes such as petroleum refining or food
processing, and the hot water is typically used for laundry, dishwashing, space
heating, cooling, and dehumidification. In a bottoming cycle system, also
referred to as “waste heat recovery,” fuel is combusted to provide thermal
input to a furnace or other industrial process. Any heat rejected from this
process is then used for electricity production.
