Abstract
A 600 MW supercritical coal-fired unit using wet slag operation, normal operation of machine in dregs to slag discharge of water per hour in 38. 50 m3 , deviated from the national advocacy of energy-saving, water-saving, environmental protection concept. On the basis of ful investigation and study and test, by adding ma-chine slag water cooler in dregs, cancel ed the slag water circulation system and a series of work, to zero dis-charge slag water machine in dregs into shape. After slag water zero emissions made in dregs machine, ma-chine in dregs and slag water system running smoothly, slag water system defect rate decreased obviously, and greatly reduces the operation maintenance personnel's work load and energy saving, water saving effect is remarkable, for wastewater zero emissions coal-fired unit took a solid step, implement the transformation for the same type unit laid a good foundation.关键词
