5852. Br³nler, O. H. U. March 10. Burners, applications of.-In apparatus for forming nitric acid, compressed oxygen enters by the pipes e, nitrogen through the pipe g, and combustibles, such as oil, gas, or coal-dust, by the pipes f; the radial arrangement of the pipes e sets up a whirling motion in the gases and assists the combustion. The nitrogen and oxygen may be previously mixed and the mixture admitted by the pipes e. The flame leaving the mouth h of the furnace penetrates the water contained in the outer tank a; the oxides of nitrogen become dissolved in the water, giving a solution of nitric acid, which may be drawn off by the valve i, while products of combustion and steam escape through the valve c.
