Abstract: The Fularji General Power Plant has difficult task of peak regulation. When the boiler operated in low load, some problems occurred, which include that the boiler combustion stability and the water cycle safety of water wall were impaired, the house service consumption rate was raised, and etc. Some measures, such as mixed firing with various grades of coal, putting three mills and one forced draft fan in operation, adopting sliding pressure operation etc., were adopted. Then the problem of boiler safety and economical operation in low load was solved.

Key words: boiler operation in low load, stable combustion, safety operation technology, economical efficiency
