Tag: cogeneration systems

In separate production of electricity, some energy must be discarded as waste heat, but in cogeneration this thermal energy is put to use. All thermal power plants emit heat during electricity generation, which can be released into the natural environment through cooling towers, flue gas, or by other means.

Cogeneration Utilizing Natural Gas-fired Reciprocating Engines

Cogeneration Utilizing Natural Gas-fired Reciprocating Engines

Cogeneration systems, also known as combined heat and power, have traditionally been installed by larger industrial users with high steam and power demands and by smaller, institutional users such as universities and hospitals. Since the early 2000s, smaller industrial and commercial companies have discovered cogeneration utilizing natural gas-fired reciprocating engines,

Benefits of Community Microgrids

Benefits of Community Microgrids

However they are defined, everyone agrees community microgrids provide benefits. Centralized utility systems and aboveground distribution lines expose customers to regional and local outages, “and while they are highly reliable, centralized utility grids can’t ensure local resilience,” notes Peter Douglass, project manager for the Microgrid Institute, a collaborative organization supporting global development of microgrids and distributed energy

The Physics of CHP Cogeneration and Heat Engine Efficiency

The Physics of CHP Cogeneration and Heat Engine Efficiency

How does CHP work? To understand CHP you have to begin with the Carnot cycle, and how it describes the function and efficacy of any heat engine. The thermodynamic Carnot cycle (proposed by Nicolas Carnot in 1824) is a four-stage process that describes the reciprocal operations of a heat engine

Making Power Multitask With CHP/CCHP

Making Power Multitask With CHP/CCHP

Cogeneration, or combined heat and power (CHP), uses a heat engine or power station to generate electricity and heat for onsite uses. Trigeneration, or combined cooling, heat, and power (CCHP), is the simultaneous generation of electricity and useful heating and cooling as a result of the combustion of fuel or

Better Together

Better Together

“Waste not want not” is a respected proverb in many engineering applications. However, according to the three laws of thermodynamics, waste heat is inevitable in any working system. And, while it is physically impossible to prevent the generation of waste heat, a power system operator can make a virtue out

Connectivity And Resilience

Connectivity And Resilience

The great northeast power blackout of 2003 was a reminder that reliance on large grids has widespread implications. The power outage—lasting several days in some areas—affected millions in the US and Canada. Nearly a decade later, Hurricane Sandy left the area without power for weeks. Many in the energy industry

Turbines and Non-Traditional Fuels

Turbines and Non-Traditional Fuels

In recent years, turbine manufacturers have been taking a number of steps to make their equipment more environmentally friendly in terms of improved efficiency and performance, reduced emissions, and such. However, what is even bigger news is how turbines are being used as parts of larger renewable and environment-conscious projects.
