BURNER FOR PRODUCING ACETYLENE

摘要

A burner for producing acetylene by a method of thermooxidative pyrolysis of methane comprises a modular gas-distributing device with channels for supplying a gaseous mixture and with channels for supplying stabilizing oxygen, said channels being connected to a reservoir for supplying the stabilizing oxygen. The invention is novel in that the gas-distributing device is in the form of the following, providing guidance jointly: a gas-distributing monoblock unit with channels machined in a single piece therein for supplying a gaseous mixture and stabilizing oxygen, and a reservoir for supplying the stabilizing oxygen. The upper part of the gas-distributing monoblock unit is in the form of a cone with a generatrix in the shape of a cycloid (brachistochrone); and inlets into the gas channels are in the form of gradually tapering sections with a transition from a trapezoidal section to a trapezoidal section with a convergence angle of a = 40-60̊. The technical result of the proposed invention consists in a substantial increase in the service life of the burner and in the efficiency thereof.
