<p>PROBLEM TO BE SOLVED: To keep a gas in a region of jetted height in a furnace, without causing substantial rising in oxidants and/or fuel toward a roof, when independent jetting of fuel and oxidant is used. SOLUTION: This burning method relates to the combustion method with a furnace comprising a floor, where an insert which is heated is allocated and a roof positioned above the insert, combustible fluid and oxidant fluid are separately jetted between the surface of the insert and the roof while the oxidant and fuel are jetted at two different levels, and the ratio of impact forces between those of combustible fluid and oxidant fluid (m2 .v2 /m1 .v1 ) is set to about 1/3 or more. M is the mass flow-rate of a top part fluid, v1 is its jetting speed into the furnace, m2 is the mass flow-rate of a bottom part fluid, and v2 is its jetting speed into the furnace.</p> |
