On the basis of analysing realization of oil-saving ignition and oil-saving combustion stabilization on W-shaped flame boilers by using burners strengthened in two aspects

the control strategy for the oil system

the pulverized coal system

the furnace safety supervising system(FSSS)

the boiler runback system

and the boiler's combustion regulating system for burners strengthened in two aspects has been put forward.The application of above-mentioned control strategy on W-shaped flame boiler for 360MW unit burning inferior anthracitic coal in Huaneng Luohuang Power Plant shows that the control strategy for said burners not only can satisfy the control requirements in oil-saving ignition and oil-saving combustion stabilization in boilers

but also can satisfy the requirements in safe operation under condition of different coal qualities and of different operating conditions

the oil-saving ratio reaches 80%.
