Abstract: According to the latest requirements of Ministry of Environmental Protection, atmospheric pollutants of coal-fired
power generating units should achieve ultra-low emissions, at the same should meet the requirements of denitration commissioning
under full load. This paper discussed the main measures of the current implementary denitration transformation under low load,
and then pointed out the problems should be paid attention in engineering transformation.

Key words: denitration device; economizer; No.0 high pressure heater
