COMBUSTOR OF HYDROCARBON BASED FUEL AND DEVICE COMPRISING COMBUSTOR OF HYDROCARBON BASED FUEL AS HEAT GENERATION SOURCE

摘要

The present invention is configured such that a combustion furnace has a length long enough to place a position of a tip of a flame further inside therein than a position of the other end thereof and also to provide a predetermined distance between the position of the tip of the flame and the position of the other end, an inner diameter of the combustion furnace takes a value not smaller than the minimum value in such a range that does not come into contact with the flame but a value thereabout, and a fluid passage of oxygen-containing gas is restricted to be narrow at one or a plurality of places in an area from the tip of the flame within the combustion furnace to an exhaust port.
