In order to comprehensively utilize the software and hardware resources of distributed control system （DCS） and management information system （MIS）

a combined method of using DCS side configuration and MIS side programming has been put forward for solving the problem of on-line monitoring and management of the service life for boiler components

and a set of on-line monitoring and management system for service life of boiler drums being developed. The said system has been already used for 320 MW coal-fired unit in one power-generation company
