Abstract

The invention relates to a multi-channel burner nozzle used for an active lime rotary kiln. A trolley is arranged on a guide rail via wheels. A front-end adjustment frame and a back-end adjustment frame are respectively fixed in front of and at the back of the upper end of the trolley. The front-end adjustment frame and the back-end adjustment frame support the main body of the burner nozzle. A motor is fixed on the trolley and drives wheels via a speed reducer, a chain wheel and a chain. The burner nozzle body comprises a plurality of tubes in coaxial sleeve arrangement. Except the thinnestcentral tube, the other tubes are ring-shaped. The tubes define a central duct, a coal duct, a blast furnace coal gas duct, a swirling flow duct and an axial flow duct, from the center to the edge. The central duct, the swirling flow duct and the axial flow duct communicate with a first-stage duct via butterfly valves. A refractory protective coating is formed at the front end of the main body ofthe burner nozzle and embedded inside with heat-insulating support nails. The multi-channel burner nozzle can prevent ring formation.

Description

technical field [0001] The invention relates to a multi-channel burner burner for an active lime rotary kiln. Background technique [0002] The fuels that can be used in the production of activated lime rotary kiln include natural gas, high calorific value gas, heavy oil and coal. The currently used burner burners lead to frequent ring formation in the rotary kiln, which seriously affects the production of the enterprise. Frequent shutdown of the kiln brings the following problems: First, it takes 30 hours or even longer from the shutdown of the kiln to the removal of rings, which seriously affects its production operation rate; It is easy to fall off, which seriously affects the service life of refractory bricks. Invention content: [0003] In order to overcome the disadvantages of the prior art, the present invention provides a multi-channel burner burner, which can greatly prolong the loop forming time. [0004] The technical solution adopted by the present invention...
