AI Technical Summary

Technical Problem

Existing auto-push control systems for injectors in reactors face challenges in maintaining a consistent gap between the injector's distal end and the reactor's outer wall, leading to potential damage and wear due to thermal shock, which complicates maintenance and increases operational costs.

Method used

An auto-push control system equipped with sensors and a controller that calculates and compensates for the insertion length of the injector based on real-time wear measurements, ensuring a consistent gap is maintained between the injector and the reactor's refractory material.

Benefits of technology

Minimizes deformation and damage to refractory materials, reduces maintenance time, and enhances operational productivity by preventing unnecessary wear and extending the injector's lifespan.

Abstract

The technical idea of the present disclosure provides an auto-push control system comprising: a reactor comprising an outer wall; an injector configured to penetrate the outer wall of the reactor and be inserted into the reactor; a sensor placed in the injector; and a controller configured to control an insertion distance or an insertion rate of the injector into the reactor, wherein the controller is further configured to: calculate a loss length of the injector based on a signal from the sensor; and compensate for the insertion distance of the injector based on an insertion length depending on a preset insertion rate of the injector and the calculated loss length of the injector.
