CONSTANT VOLUME COMBUSTION APPARATUS FOR COMBUSTION CHARACTERISTIC EVALUATION FOR LIQUID FUEL OIL

摘要

PURPOSE:To obtain a combustion apparatus which enables observation of a flame propagation state of a liquid fuel oil and easy and accurate measurement of a combustion speed in a laboratory manner. CONSTITUTION:A combustion apparatus is provided with a burning apparatus body which has a combustion chamber 11 closed inside while having a window 12 for observation, a heater 3 mounted on the external surface of the burning apparatus body, a temperature detector 4 for detecting the temperature of the combustion chamber 11, a liquid fuel oil feeder 5 to supply a specified amount of a liquid fuel oil to the combustion chamber 11, an air feeder for supplying air to the combustion chamber 11, a stirrer 7 having a stirring member 22 movable in the combustion chamber 11 and an ignition plug 8 which can form a spark in the combustion chamber 11. When performing a measurement, first, the combustion chamber 11 is purged inside and then, the liquid fuel oil as sample is supplied thereto. The stirring member 22 is operated manually to form a premixed gas with the air. Thereafter, the mixed gas is ignited. The state of flame propagation is observed through the window 12 for observation.
