Measurement of Calorific Value Containing Organic Matter with a Large Amount of Water

Abstract

It has been known that the pyrolysis liquor obtained from pyrolysis of municipal wastes or biomass can be used as new liquid fuel.
The pyrolysis liquor from cellulosic matter generally contains a large amount of water, which has an evil effect on ignition or combustion and makes it difficult to obtain its precise calorific value by traditional measuring methods.
We studied a method which enables us to measure the calorific value precisely, using methyl alcohol aqueous solution with moisture up to 100% as a sample. As a result, the measurement of the precise value could be taken by adding nearly the same amount of benzoic acid as that of the sample.
By this method, the calorific value of the pyrolysis liquor from wood or municipal wastes was measured, and it was found that the value is in inverse proportion ratio to the water content of the liquor.
