STEP 4 The captured heat is then used for various purposes, such as local heating and hot water. It can also be used to create steam to generate more electricity in a process known as “combined-cycle” generation.

Select each number to learn about that step in the process
STEP 5 In a process known as “tri-generation” — or “combined cooling, heat and power” — hot water from the co-generation process can also be used to power an absorption refrigeration system to create chilled water for applications such as air conditioning or refrigeration.

More Power To You
Each year, as much as half of the energy that goes into powering industry is lost as “waste heat”, according to the U.S. Department of Energy. That’s a big resource disappearing out the door. But we can do something about it with cogeneration — aka combined heat and power — a technology for capturing waste heat and putting the energy back to work. Cogeneration works best when power plants are close to the infrastructure they serve — factories, major buildings, mine sites and so on. But the savings they drive are significant for overall efficiency, reduced fuel consumption — and greenhouse gas emissions.  
How Cogeneration Works
STEP 1 A fuel source — natural gas, coal, biomass or liquid fuels, for example — is burned inside a combustion chamber.
Heat recycling in energy production — aka cogeneration — is an efficient way to save on costs and reduce environmental impacts
STEP 2 Electricity is produced when the flow of hot gases from combustion is channeled to a turbine that drives a generator.
STEP 3 Heat generated during fuel combustion is captured in a heat-recovery boiler
