    초록 By the experiment of a mode Ondol heating system gas flow characteristics in a briquette flue tube was investigated. As a heat source electric heater was used, which renders steady flow condition of air, working fluid.
    It was observed that the flow augmentation may be obtained by increasing the vertical elevation of the flue tube, namely increase in the tube length or increase in the tube inclination, and the gas temperature at the tube entrance among several factors which augment the flow rate slope of the flue tube has the most striking effect and then the temperature of gas entering the tube. Increase in length of the tube also augments the flow but the rate of augmentation is so small that it gives little assistance to improvement of the flow.
    The flow in a briquette flue gas does not essentially satisfy the one dimensional steady flow assumption. It is also observed that the flow begins to accompany irregular velocity fluctuation as inclination of the tube increases.
