The volume of waste materials generated by all nations grows exponentially, one solution is using the organic matter in waste as a fuel for energy plants. Exeter Analytical, in conjunction with a number of leading waste reclamation organizations, has developed a methodology for their Model 440 CHN Elemental Analyzer enabling determination of the suitability of a waste material for use as a fuel in waste to energy plants. The percentage Carbon, Hydrogen and Nitrogen in a waste sample, which relates directly to its energy content, can be accurately determined in as little as 6 minutes. It is a static combustion CHN Elemental Analyzer, with a unique horizontal furnace design, which enables easy removal of sample residue between each waste material analysis. This is particularly important with waste materials that typically produce a considerable amount of uncombusted residue (metals, inorganic fillers etc) after each analysis. One combustion tube will analyze in excess of 1000 waste samples without the need for removal and cleaning.
