The influence of doing not put one coal-pulverizer into service upon the operation of boiler under condition satisfying the load requirement has been analysed.Analysis shows that the said operation mode is comparatively suitable to the tangentially firing boilers.Under operation condition of doing not blend cold air into the coal pulverizing system

the above-mentioned operation mode of coal pulverizers isn't suitable to wall firing boilers and arch-firing boilers

the said operation mode of coal pulverizers doesn't affect high-temperature corrosion on the water-wall and slagging in the furnace.Only under condition of blending cold air into the coal pulverizing system

the said operation mode of coal pulverizers can be suitable to wall-firing boilers and arch firing boilers

however

the energy-saving effect has to be confirmed through test.
