Reformation and application of lignite blended burning process in 200MW unit

Abstract

Abstract: Aiming at the performance and characteristics of the boilers of the Harbin Third Power Plant of Huadian Energy Company Limited, the problem of lignite blended burning process in 200MW unit was studied. To improve the economic efficiency of the unit is taken as first purpose. According to the load of the unit and the supplied coal in different time segments of every day, the lignite blending principle was determined. Based on this, the lignite blending technology was improved; the feasibility of lignite blending in maximum ratio for the unit was discussed; and the economic efficiency of lignite blended burning was analyzed. Then the latent capacity of economic operation was excavated in largest possible, and energysaving and benefit increasing were realized truly.

Key words: blended burning, management, economic efficiency
