Abstract
The device for firing of coal-fired boilers without the use of crude oil injection finds application in the power industry. Its design prevents any contact between the plasma flow and the walls of the fuel preheating chamber and increases the effectivity of its combustion. The device consists of a muffle chamber (1) for the preheating of the fuel having a pipe union (2) fitted on its side surface in which there is a plasmotron (3) consisting of an internal electrode (4) and an emitting nozzle-electrode (6) is found from the point of intersection (A) between the axis (10) of the plasmotron (3) and the extension of the external surface adjacent of the pipe union (2) on chamber (1) for the preheating of the fuel at a distance of L = (0.8- 1)d2, where d2 is the diameter of the duct of the nozzle-electrode (6) at the external front surface (9) where the angle between the axis (10) of the plasmotron (3) and axis (11) of the preheating chamber (1) is within 30-150 degrees. 4 claims, 1 figure
