Cogeneration. Trigeneration or combined cooling, heat and power refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector. The terms cogeneration and trigeneration can be also applied to the power systems generating simultaneously electricity, heat,
gas. Trigeneration is an extension of cogeneration which involves the simultaneous production of electricity, heating and cooling. These systems recover the heat normally lost in traditional grid electricity generation and use it for heating, cooling, dehumidification and other processes. An efficient on-

Fully automated systems. Fully automated systems are exactly that – a delivery truck drops off the chipped or ground up waste wood with a live bottom floor, and a series of augers and conveyers move the wood fuel from there to the boiler. With computer controls and a laser eye that measures the amount of fuel in the metering bin,

housing complexes. The heat provided by cogeneration is ideal for space heating and for providing hot water for domestic, commercial, or industrial use. A feature of cogeneration-driven district heating systems is the option to use a variety of fuels to suit environmental, economic, or strategic priorities.
Boiler Systems Operation. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again. Hot water heating systems operate on the same principle, using hot water instead of steam to heat the radiators.
Cogeneration (CHP) Ameresco’s comprehensive energy services specialists can analyze electrical, heating and cooling needs, then develop energy conversion systems from 1 to 50 megawatts, or higher, that improve overall energy efficiency, provide secure and reliable power for mission-critical systems and pay for themselves in annual utility bill savings.

Instead of a fan and duct system, a boiler uses a pump to circulate hot water through pipes to radiators. Some hot water systems circulate water through plastic tubing in the floor, a system called radiant floor heating (see “State of the Art Heating”). Important boiler controls include thermostats, aquastats, and valves that regulate circulation and water temperature.
Efficiency Benefits. This means that two-thirds of the energy used to produce electricity at most power plants in the United States is wasted in the form of heat discharged to the atmosphere. By recovering this wasted heat, CHP systems typically achieve total system efficiencies of 60 to 80 percent for producing electricity and useful thermal energy.
Characterization of the Technologies for Cogeneration INTRODUCTION Cogeneration systems recapture otherwise wasted thermal energy, usually from a heat en-gine producing electricity (such as a steam tur-bine, gas turbine, or diesel engine), and use it for space conditioning, industrial processes, or as an energy source for another system component (31 ).
