Topping cycle plants primarily produce electricity from a steam turbine. The exhausted steam is then condensed and the low temperature heat released from this condensation is utilized for e.g. district heating or water desalination. Bottoming cycle plants produce high temperature heat for industrial processes, then a waste heat recovery boiler feeds an electrical plant. Bottoming cycle plants are only used when the industrial process requires very high temperatures such as furnaces for glass and metal manufacturing, so they are less common.

Minimizing Running Costs for Pumps in Gas Turbine Power Generation

Minimizing Running Costs for Pumps in Gas Turbine Power Generation

Large scale, high performance pumps have traditionally been designed to meet the specifications of a particular application without the need for speed control. However, changes in operating conditions after the initial installation can result in a pump not operating near its best efficiency point (BEP), which makes the overall process

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

“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

Guest Commentary: Water Loop Heat Pumps

Designing net zero energy buildings for new construction and for renovation of existing buildings presents a diverse set of challenges. It requires analyzing the unique energy use of the entire building and then designing a system that can reduce the net energy footprint without sacrificing functionality or comfort. And as

Bringing Onsite Power to Hospitals – Part 1

The $10 million investment made sense, and would bring huge yearly energy savings to Abington Memorial Hospital in Abington, PA.

And fortunately for Richard Szatkowski, corporate director of plant operations for the hospital, the members of his board of directors felt the same way. And because of that, the hospital last

Cogeneration Is Talking Trash

Cogeneration Is Talking Trash

Back in the 1880s, the first electric generators were powered by steam engines. The process was quite inefficient compared to today’s standards, but one technique was employed back then: the basis for modern combined heat and power (CHP) generation. The excess waste steam was harvested for process use or to
