In this paper,a set of high temperature calorimetric system for measurement of heat sink of endothermic fuels has been developed. Its constructional details and operational principles are also related. The thermal constant for the apparatus at different temperature has been determined through a electric heating method. Calibrations are also carried with the heat sink of nitrogen.The results are agreement with those reported in the literature and corroborate the correct functioning of the calorimetric system.By using this apparatus the heat sink of endothermic fuel TQ 7 at 600,700 and 800℃ have been measured. It was shown that this calorimetric system is suitable for the selection of endothermic fuels.
