I. Overview of Coal Mill Hot Air Isolation Door: The Coal Mill Hot Air Isolation Door is a crucial auxiliary equipment for boilers, installed in situations where cold and hot air channels of power plant boilers require shutdown and isolation, such as the inlet and outlet air ducts of the coal mill. This product operates reliably, with flexible opening and closing, and tight sealing, fundamentally addressing the previous shortcomings of inadequate closure and excessive closing time. It greatly facilitates equipment switching and maintenance shutdown, and has now been widely used in major power plants across the country.
