SP Industry Calorimeter for Rate of Heat Release Measurements Up to 10MW

摘要

The Swedish National Testing and Research Institute (SP) has installed a 10 MWfire calorimeter for rate of heat release measurements, similar to the one at Factory Mutual Research Corporation (FMRC). It can be used to classify commodities with respect to their fire hazard, to evaluate the efficiency of sprinkler systems, for chemical analysis of the combustion gases from hazardous fires, to produce input data for the fire modelling, etc. A large hood collects the fire gases and leads them into a duct where gas velocity, gas temperature, smoke density and contents of oxygen, carbon dioxide and carbon monoxide are measured. On the basis of these measurements mass flow and rate of heat release are calculated. The rate of heat release is calculated according to the oxygen consumption principle. The upper limit for measurements is approximately 10 MW and the lower is 0.1 MW.
