Engine Thermal Efficiency - an overview | ScienceDirect Topics

Similarly, if another 15% of the fuel energy goes to EGR cooler heat rejection, another 1.5% of the fuel energy can be recovered from the EGR gas flow by using a Rankine cycle. This total 3.5% of the fuel energy can be added to the engine crankshaft power to make engine thermal efficiency increase from 50% …

Desalination - Wikipedia

Desalination is a process that takes away mineral components from saline water.More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater (especially sea water) is desalinated to produce water suitable for human consumption or irrigation.The by-product of the desalination process is brine.

Compressor - Wikipedia

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.An air compressor is a specific type of gas compressor.. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while

Oct 31, 2017 · The remaining 10% is lost. High-efficiency furnaces have AFUE percentages above 90%. Think of AFUE as the gas mileage of your furnace. Older, low-efficiency furnaces have an AFUE rating between 50% and 70%. Mid-range efficiency furnaces around 80% to 85%, while high-efficiency furnaces have AFUE rating above 90%, sometimes as high as 98.5%.

Biomass heating system - Wikipedia

Benefits of biomass heating. The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and/or electricity with less effect on the environment than fossil fuels. This type of energy production has a limited long-term effect on the environment because the carbon in biomass is part of the natural carbon cycle
