Tag: CHP

Combined heat and power (CHP) is used to describe the process of obtaining electricity and useful heat from a common fuel source. In years past, this process was called cogeneration, a term most engineers are familiar with. Whether it is called CHP, cogeneration, or trigeneration (heating, cooling, and electric production), the concept offers remarkable promise for energy efficiency in a world that wants to lower costs, reduce dependence on fossil fuels, and cut greenhouse gas emissions.

What do the Excelsior Hotel, Cathedral Village Retirement Home, Grand County High School, Statz Farms, Willard Apartments, and Supreme Sports Club have in common? They all represent the new face of the combined heat and power (CHP) market—relatively small commercial facilities that are installing CHP to save money on energy

You’ve seen her enigmatic smile. It allures, engages, and seems to interact with those standing before her. The Mona Lisa, Leonardo da Vinci’s sixteenth-century masterpiece, appears more alive than any other portrait. In fact, some believe that by integrating elements of anatomy, chemistry, and optics into his artistic process, Leonardo

Data centers, hospitals, and manufacturers can’t lose power for even a minute. The same can be said for financial institutions. Unfortunately, public power infrastructure in cities across the United States is aging. And as it does, power failures are becoming more common.

The famous saying “smaller is better” is not necessarily true. A more accurate statement would be that “appropriate scale is better.” This brings us to the use of microturbines and their appropriate applications. Micro turbines are not actually tiny; they are still relatively large and powerful machines. But compared to

When I was a child, the words “Choose Your Own Adventure” rang with the same exhilarating thrill as the recess bell. As the title of a popular book series, the phrase was indicative of freedom. Books like By Balloon to the Sahara, Search for the Mountain Gorillas, and Mystery of the Maya let shy kids like me

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

In 1915, a tragic farm accident reported in The Fruit Grower and Farmer was a mere footnote of local news. Patients from the State Hospital in Athens, OH, whose job was “to tramp down the silage comprised of corn stalks and leaves” were found asphyxiated in a tower silo. The report says

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,
