The items and results of oil-saving test in start-up and shutdown process of the coal pulverizer for wall-type coal-firing boilers of 350MW units in Huaneng Dandong Power Plant have been presented

the influence of burners' layout mode in boiler as well as start-up and shutdown mode of the coal pulverizer upon oil-saving result being briefly analysed.Results show that:(1)the two boilers in Huaneng Dandong Power Plant can realize start-up and shutdown without combustion-supporting oil according to daily start-up and shutdown mode and under corresponding load of them

the oil-saving rate up to 100%;(2)the layout mode of burners is helpful to implement oil-saving

the excellent ignition behavior of fuel coal and strong combustion-stabilizing capability of the boilers are important guarantee to implement oil-saving.
