low heat value

low heat value

[′lō ′hēt ‚val·yü]
(thermodynamics)
The heat value of a combustion process assuming that none of the water vapor resulting from the process is condensed out, so that its latent heat is not available. Also known as lower heating value; net heating value.

Polyethylene (PE) powder, with average diameter between 2 mm and 3 mm and low heat value of 46.30 MJ/kg, was used to simulate plastic waste.
The low heat value of the fuel is dependent on the content of the fuel and mathematically this can be describes as follows:
This assumption differs because it applies to the low heat value, which in this case remains constant.
Then return to low heat value again, the application will continue performs a square wave until the drying process reach to the end.
