Qualifying Combined Heat and Power (CHP) activity
The EU 2002 draft and 2004 final CHP Directives propose qualifying CHP activity with the quality norm. This norm benchmarks the energy efficiency of CHP plant outputs on external reference power and heat efficiencies. Because the quality norm amalgamates cogeneration and condensing activity its application entails particular perverse effects for high-quality and adapted scale investment in CHP ...

Combined Heat and Power (CHP) essentials
'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

Flexible Combined Heat and Power (CHP)
The essence of combined heat and power technology, over recent decades, is to provide continuous supplies of electricity and heat. This is done at the highest levels of fuel efficiency – typically reaching around 90% – meaning that this has lower carbon emissions than grid-supplied electricity. Historically thermal power plants supplying the grid rarely had heat recovery. Compared to ...

Decentralised energy systems: state of the art and potentials
The increasing liberalisation of the energy market as well as the ecological and business environment of public heat and power supply are leading to a re-evaluation of established and innovative energy conversion systems. A more efficient usage of fossil and regenerative primary energy resources is to be achieved by decentralised systems providing combined heat and electrical power. This paper ...

US to lead on efficient design of energy systems
Despite the availability of Combined Heat and Power (CHP) technologies and proven benefits and performance of these systems, projects often are not implemented even when investment is compelling. The United States will lead this effort, building on its CHP Partnership Program to identify and clear barriers to efficient design of on-site energy systems. The project will promote collaborative ...

Exergy and exergoeconomic analysis and optimisation of diesel engine based Combined Heat and Power (CHP) system using genetic algorithm
In the present study, a diesel engine based Combined Heat and Power (CHP) system is optimised using exergoeconomic concept and genetic algorithm. For this purpose, the CHP system is first thermodynamically analysed through energy and exergy. Then cost balances and auxiliary equations are applied to subsystems. Finally an objective function representing fuel cost, cost of exergy loss and ...

Assessing the benefits of a provision of system services by distributed generation
Distributed Generation (DG) units are said to have the potential to become an integral part of the future power systems. Today, DG units are characterised by high specific investment costs, but nevertheless are politically promoted because of their high degree of energy efficiency and their capability of reducing the current dependency on fossil fuels. However, at longer term DG units have to ...

First industrial application of an open absorption cycle for heat transformation in a district-heating network
The first plant for high temperature utilisation of higher heating value was realised under industrial conditions in a combined heat and power plant. The technology results in an increased heat recovery temperature and a stronger dehumidification of the flue gas. Beyond that, the use of large solution flow within an adiabatic absorber enables to combine gas scrubbing and dehumidifying. Economic ...
