PURPOSE:To stop the supply of kerosene to a kerosene gasification device and inform a person of an abnormal condition when an absorbance is above a set value by measuring a yellowing chromaticity as the absorbance with a detector for deterioration of kerosene. CONSTITUTION:When the switch of a power source is turned on, a heater 14 for a kerosene gasification device 5 is heated and a kerosene pump 3 is operated and at the same time an open and closed valve 7 for gas injection is opened to inject kerosene gas from an injection nozzle 13 for kerosene gas. At that time, this gas is moderately mixed with room air which is sucked in together with the gas simultaneously in the inside of a burner 6 and a mixture is ignited by an ignition plug to generate a burning flame 15. When deteriorated kerosene is supplied to a kerosene storage tank 2, the luminous intensity of an ultraviolet ray 18 generated from an ultraviolet ray emission element 16 is absorbed by a yellow component of the deteriorated kerosene to reduce the amount reaching an ultraviolet ray receiving element 17 and judgement for an abnormal condition is indicated by an operation circuit 19. Thereby, a control circuit 20 is operated to bring the pump 3 in an open condition and stop the start of burning and also a display 21 indicating the detection of abnormal kero-is operated to inform a person of an abnormal condition. |
