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 ...

Effect of exergy optimisation on a cogeneration system's CO2 emissions according to different demand patterns
The objective of this work is to verify how different operational strategies affect the CO2 emissions of a cogeneration system according to different demand patterns. The operation strategies studied were focused in running cost and exergetic efficiency. The results show that the optimal exergetic efficiency strategy generated the highest emissions reduction. The operation with the highest ...

Small-scale heat and power at B.C. mills
Fred Scott introduced the B.C. Bioenergy Network (BCBN) as an alliance between Pristine and Nexterra Energy Corp. BCBN is a network of 15–20 individuals, with 10 MW power plants located across B.C. at mill operations in forest communities. Nexterra has developed a proprietary gasification technology that “takes wood waste material and [produces] clean burning synthetic gas or syngas,” Scott said. ...

Exergy performance analyses of an irreversible two–stage intercooled regenerative reheated closed Brayton CHP plant
A combined heat and power (CHP) plant model composed of an irreversible constant– temperature heat reservoirs two–stage intercooled regenerative reheated closed Brayton cycle and a heat recovery device is proposed using finite time thermodynamics. By taking dimensionless exergy output rate and exergy efficiency as the objectives, the performance of the plant is investigated. The two cases with ...

Energetic and exergetic efficiency analysis of an indirect fired air-turbine combined heat and power system
The aim of this paper is to analyse the performance of an intercooled reheat regenerative indirect fired air turbine based combined heat and power system using the first and second law of thermodynamics. The energetic and exergetic efficiencies have been defined. The effects of overall pressure ratio, cycle temperature ratio, pressure losses and process steam pressure on the energetic and ...

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 ...

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 ...

Residential Heat and Power - Case Study
A wide variety of technologies are available to provide heating and electricity to our homes. In countries with a stable electricity grid, lighting and heating are taken for granted; but the desire for cleaner energy is highlighting how dirty grid electricity is around the world, and concerns over the future of nuclear power are adding to the debate. Many countries also have a network that ...

Is waste heat the silver bullet?
The energy industry tends to get stuck on certain words. Silver bullet is one of them. Insiders and policymakers often like to say there is no silver bullet to fix US energy woes. We need a portfolio of solutions – renewables, efficiency, smart grid, transmission expansion, coal sequestration, etc. That may be true, but Tom Casten begs to differ. Casten is a bit of a rock star in the field of ...
