대용량 헵탄 풀버너 연소의 발열량 측정 기술

다국어 초록 (Multilingual Abstract)

Improved technique to estimate heat release rate from combustion in a large-scale con-calorimeter is studied. It takes a mixing effect within a large space into account, and adds a model, based on a constant stirred tank reactor equation, that readily predicts oxygen concentration at a measuring station into the conventional HRR measurement system based on Thornton’s rule. The developed technique is then validated with a series of n-heptane pool fire tests with combustions of 68 L of n-heptane. When the combustion efficiency was assumed 100% at an open space experiment, it is 28.9 MW and natural convection is dominant for mass transport of species. As a result, HRR is 32 MW at its maximum, which is much higher than it was expected. This is caused by a vigorous forced convection near the heptane flame due to the make-up air (around 4,000 cu. m/min), which makes it be evaporated more faster.
