FUELS
Quality characteristics of fuels
Regardless of the the specific fuel type (wasteoils, waste derived fuels, alternative fuels,
fossil or non fossil fuels), all good quality fuels share common characteristics:
Efficient burning. Of importance are the following parameters:
• Calorific value
• Moisture content
Consistency of characteristics, as these affect the performance of the combustion
facility
• Chlorine (Cl) content
• Ash content
• Chemical properties
ALS Life Sciences carry out specific tests to check the burning efficiency
and the characterisitcs of different classes of fuels, distinguished here
as liquid, solid fossil and solid non fossil. Determinations are performed
in the samples as received („ar“, mentioned below as „original“) and
in the dry matter, in case of solid fuels/waste.

Gross calorific value and net calorific value are routinely determined at
constant volume. If you need these parameters at constant pressure, please
contact your Sales representative.
