2. Waste-to-energy plant - Wikipedia

   en.wikipedia.org/wiki/Waste-to-energy_plant

   The waste is then stored until it is time for burning. A few plants use gasification, but most combust the waste directly because it is a mature, efficient technology. The waste can be added to the boiler continuously or in batches, depending on the design of the plant. In terms of volume, waste-to-energy plants incinerate 80 to 90 percent of ...

3. Waste heat recovery unit - Wikipedia

   en.wikipedia.org/wiki/Waste_heat_recovery_unit

   Traditionally, waste heat of low temperature range (0-120 °C, or typically under 100 °C) has not been used for electricity generation despite efforts by ORC companies, [citation needed] mainly because the Carnot efficiency is rather low (max. 18% for 90 °C heating and 20 °C cooling, minus losses, typically ending up with 5-7% net electricity).

4. Water heat recycling - Wikipedia

   en.wikipedia.org/wiki/Water_heat_recycling

   When recycling water from a bath (100–150 litres) or shower (50–80 litres) the waste water temperature is circa 20–25 °C. An in-house greywater recycling tank holds 150–175 litres allowing for the majority of waste water to be stored. Utilizing a built in copper heat exchange with circulation pump the residual heat is recovered and ...

   Texas oil extraction operations in year 2019 included the flaring of 250 billion cubic feet of associated petroleum gas, with much of it concentrated in the Permian basin near Midland. [5] This amount of wasted natural gas could have met all of the state's residential heating and cooking needs, [ 6 ] [ 7 ] or could have generated an amount of ...

   The U.S. EPA defines the term "used oil" as any petroleum or synthetic oil that has been used, and as a result of such use is contaminated by physical or chemical properties. [2] "Used oil" is a precise regulatory term. "Waste oil" is a more generic term for oil that has been contaminated with substances that may or may not be hazardous. [1]

9. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   The furnace transfers heat to the living space of the building through an intermediary distribution system. If the distribution is through hot water (or other fluid) or through steam, then the furnace is more commonly called a boiler. One advantage of a boiler is that the furnace can provide hot water for bathing and washing dishes, rather than ...
