1) It is common to describe energy values or heat of combustion values as higher heating values (HHV) for moisture-free material and gross heating values (GHV) or lower heating values (LHV) for material containing moisture.
The average heat of combustion was not changed significantly with the addition of 8 wt% OMMT, which is typical of condensed-phase flame-retardant mechanism in polymer-layered silicate nanocomposites.
This empirical principle is based on the observation that, generally, the net heat of combustion of any organic material is directly related to the amount of oxygen required for combustion so that approximately 13.
It is clear that the effective heat of combustion is not a constant; it is roughly 12 MJ/kg for the first part of the test, but increases to around 30 MJ/kg during the charring period at the end of the test (Babrauskas 2008).
Barnes and Sinclair (1984) reported similar results for a comparison of gross heat of combustion for living and spruce budworm-killed balsam fir.
The use of NPCC in PE products significantly improves the mechanical property of the synthetic plastic, increases its heat-resistant capability and reduces the quantity of heat of combustion and secondary pollution.
To decrease the typical HRR established fire retardants usually reduce the combustion efficiency and/or effective heat of combustion of the volatile pyrolysis products (flame inhibition, fuel dilution), decrease the amount and rate of combustible volatiles (charring, barrier formation/intumescence) or cooling the system in the gas or condensed phase (water release, endothermic reactions.
The heat of combustion generated in the fluidized bed is transformed by a bottoming steam cycle (Rankine) whereas the flue gas energy is transformed by a topping cycle (Brayton) in the gas turbine.
Heat loss sources to offset the sensible heat of combustion are those by radiation, convection and heat lost out the top of the furnace.

The fuel has been measured for its compatibility with the ASTM standard and has several favourable characteristics, comprising its low freezing point, high thermostability and high net heat of combustion.
