3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Combustion gross calorific value grossheatofcombustion
Qg
Unit mass of fuel in a constant volume combustion in a closed container, in addition to water condensed into a liquid, the remaining gaseous product are released when the
energy of.
NOTE. The fuel may be liquid or solid, containing only carbon, hydrogen, nitrogen and sulfur. In oxygen gaseous products of combustion are carbon dioxide, nitrogen oxides, sulfur dioxide and
liquid. In this process, the initial temperature of the fuel and oxygen as well as the final temperature of the combustion products is 25 ℃.
3.2
Combustion net calorific value netheatofcombustion
Qn
A unit mass of fuel combustion at constant pressure, all of its product (including water) are released gaseous energy.
NOTE. The fuel may be liquid or solid, containing only carbon, hydrogen, oxygen, nitrogen and sulfur, oxygen in gaseous combustion products of carbon dioxide, nitrogen oxides, carbon
