WASTE TECHNOLOGIES: WASTE TO ENERGY FACILITIES
large.stanford.eduThermal efficiencies above 30% are possible in combined heat & power configurations, where a proportion of the heat which is rejected to atmosphere in plants that produce only electricity is recovered for process use. The highest levels of energy recovery are achieved in heat-only configurations where thermal efficiencies can exceed 80%.
Overview of Unit 3 The Issue of Renewable Energy
www.aps.eduthermal unit or Btu . One Btu is the heat energy needed to raise the temperature of one pound of water one degree Fahrenheit. A Btu is quite small. For example, if allowed to burn completely, a wooden kitchen match gives off one Btu of energy. A quad is used to measure very large amounts of energy. A quad is equal to one quadrillion (1,OOO,OOO ...

www1.eere.energy.govfoams are rated with a Long Term Thermal Resistance (LTTR) R-value representing a 15 year weighted R-value. This is in response to issues of thermal drift of the polyisocyanurate products. Thermal drift occurs due to the gasses produced during the forming of the foam. These gasses slowly diffuse out of the product over time and are replaced by air.
