Solar thermal collector - Wikipedia

A solar thermal collector collects heat by absorbing sunlight.The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non water heating devices such as solar air heaters.. Solar thermal collectors are either non-concentrating or concentrating.

Thermal Conductivity of some selected Materials and Gases

Thermal conductivity is a material property that describes ability to conduct heat.Thermal conductivity can be defined as "the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions"

Thermal comfort - Wikipedia

Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation (ANSI/ASHRAE Standard 55). The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate.

CHAPTER 2 Steam Generators - EMU Academic Staff Directory

The chemical energy available in fossil fuel (i.e., coal, fuel oil, gas) is converted to heat energy by combustion in a steam generator. The heat thus liberated is absorbed by continuously feeding water in a combination of heat-transfer surfaces, resulting in a continuous generation of steam.

How Efficient are Engines: Thermodynamics and Combustion

Jun 27, 2018 · The Rentar Fuel Catalyst, for example, can increase combustion efficiency and therefore, fuel efficiency by between 3% and 8% in over-the-road vehicles. On heavy machinery, the fuel efficiency increase is even more dramatic. By adding a Rentar Fuel Catalyst to a furnace or boiler that burns heavy fuels, the increase can be 30% or more.

Thermal mass - Wikipedia

The equation relating thermal energy to thermal mass is: = where Q is the thermal energy transferred, C th is the thermal mass of the body, and ΔT is the change in temperature.. For example, if 250 J of heat energy is added to a copper gear with a thermal mass of 38.46 J/°C, its temperature will rise by 6.50 °C.
