Combined heat and power—sometimes called cogeneration—is an integrated set of technologies for the simultaneous, onsite production of electricity and heat.. A district energy system is an efficient way to heat and/or cool many buildings from a central plant. It uses a network of pipes to circulate steam, hot water, and/or chilled water to multiple buildings.

Combined heat and power (CHP), also known as cogeneration, is: The concurrent production of electricity or mechanical power and useful thermal energy (heating and/or cooling) from a single source of energy.. A type of distributed generation, which, unlike central station generation, is located at or near the point of consumption.. A suite of technologies that can use a variety of fuels to ...

CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. CHP can be located at an individual facility or building, or be a district ...

1 This fact sheet is focused on topping cycle CHP where fuel is first used to generate power. In a bottoming cycle CHP system, also referred to as "waste heat to power," fuel is first used to provide thermal input to a furnace or other industrial process and heat rejected from the furnace or process is then used for electricity production.

Biomass cofiring is widely considered as the most costefficient and easily deployed way for mitigating the CO 2 emissions from the coal power sector. Apart from policy and market benefits and bottlenecks, the implementation of cofiring in a coalfired power plant is affected by several technical and environmental concerns.

Coal blending is a critically important process in the coal mining industry as it directly influences the number of product tonnes and the total revenue generated by a mine site. Coal blending represents a challenging and complex problem with numerous blending possibilities, multiple constraints and competing objectives. At many mine sites, blending decisions are made using heuristics that ...
