AI Technical Summary

Technical Problem

The burner burner is not evenly burned, which causes some burners to overheat, and some burners to be underburned, which can easily cause equipment damage.

Method used

By accurately controlling the temperature gradient of the burner and uniformly controlling the gas requirement during the burner combustion process in each set area, the gas volume segregation is avoided.

Benefits of technology

It realizes precise control of the combustion chamber temperature, avoids segregation of the gas volume, burns the burner more evenly, and extends the service life of the burner.

Abstract

The present invention discloses a burner intelligent control method for a pellet belt roasting machine, comprising the following steps: a) leak detection of the burner cut-off valve; b) ignition of the burner in the combustion chamber; c) precise control of the temperature gradient of the burner; d) uniform control of the gas demand during the burner combustion process in each set area. The burner intelligent control method for a pellet belt roasting machine of the present invention not only ensures precise control of the temperature of the combustion chamber, but also avoids the segregation of the gas amount, the burner burns more evenly, avoids overheating or under-burning of the burner, and extends the service life of the burner. The present invention also provides a burner intelligent control system for a pellet belt roasting machine.
