MEASURES AND METHODS FOR DECREASING FLUE GAS TEMPERATURE OF BOILERS
The causes leading to high flue gas temperature of SG-420/13.7-M418 type boilers for 2×125MW units in Ma'an shan Power Plant have been analysed. Through retrofitting coal-pulverizing system
combustion system and soot-blowing system
as well as increasing area of heating surface etc.
the flue gas temperature has been lowered by about 25℃
the boiler efficiency being enhanced by 1.5%~2%
hence
about one million t of standard coal can be economized in only one year
the effectiveness of retrofitting being comparatively obvious.
