IEEE 2777-2021

This recommended practice defines the principles and procedures for start-up, normal operation, shutdown, daily operation, and maintenance during normal and emergency conditions for a 300 MW to 600 MW pulverized coal-fired boiler and its main auxiliary equipment. This recommended practice applies to 300 MW to 600 MW pulverized coal-fired boilers with a balanced draft, including natural circulation and forced circulation; subcritical and supercritical once-through boilers; tangential-fired boilers; opposed-fired boilers; and so on. For specific applications, an additional document needs to be formulated by users based on this recommended practice to cover detailed procedures or normally so-called a??operation code,a?? together with the instructions of manufacturers and the experiences derived from normal operation practice.
