ABSTRACT:
A bomb-type conduction calorimeter consists of a bomb separated from a substantially infinite heat sink by several heat flow detecting elements. The bomb is enclosed by an inner copper box having a cylindrical interior and a polygonal exterior. The inner copper box is enclosed by an outer copper box having a polygonal interior. The heat flow detecting means may be several thermopiles in contact with the inner and outer polygonal surfaces. The infinite heat sink may be a constant temperature water bath. Heat flow directly from the test substance is measured, as opposed to the heat flow dissipated to the environment of the bomb. The calorific values determined are independent of the amount of water in the water bath.
