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 “operation code,” together with the instructions of manufacturers and the experiences derived from normal operation practice.
New IEEE Standard – Active. General technical recommended practice for operation of pulverized coal-fired boilers in power plants is provided, including start-up, shutdown, operation and maintenance, and emergency and failure detection/handling/prevention. In this document, a boiler with existing single units with a capacity of 300 MW to 600 MW in thermal power plants, where pulverized coal is combusted to generate electricity and/or to supply heat, is discussed. Development of boiler operation code as a reference to determine detailed operation steps and/or procedures for a particular boiler in the plant is outlined. The specifications of manufacturers, successful experiences from practice, and stipulations defined in other related high-level standards/regulations/codes are also considered.
