Abstract

1373540 Injecting free oil in furnaces, fuel atomisation F AKLUTH 19 Oet 1971 [21 Oct 1970] 48486/71 Headings F4B and F4T Oil is added to the air blast of a blast or like furnace near the tip of the tuyere 11, the oil being injected into the tuyere blast from a nozzle 1 at the centre of the tuyÞre in one or more jets at right angles to the direction of the blast, the jets having a velocity high enough to remain intact until they reach a zone near the inner wall of the tuyere, but breaking up before reaching the wall. Instead of being at right angles to the blast the jets may be directed backwards at an angle against the blast. The oil 13, Fig. 2, which may be mixed with up to 15% by weight of water or steam is forced under pressure into an eddy chamber 3 which creates turbulence in the oil stream. The flow of oil along the injection lance cools it and prevents decomposition of the oil and clogging of the nozzles.
