Improving Coal Mill Fuel Delivery through Upgrades to the Feed Valve

Abstract

This paper will discuss the replacement of a hydraulically operated triple gate valve with a pneumatically operated double gate valve acting as the inlet feed airlock to the cement coal mill. Implementing this change provides the cement plant production department with the reliability needed for fuel delivery. We will discuss technical details of the project including the issues experienced with the triple gate valve that lead to the replacement project, the specification of a double gate valve replacement, the installation details, commissioning, and a discussion of the reliability increase.
