The influence of mixedly burning Baorixile coal for 2×800 MW units in Suizhong Power Plant upon slagging in boiler

efficiency of boiler

water-wall

and equipments in coal pulverizing system

and in ash-slag handling system etc.has been analysed.Results show that the enhancement of proportioning ratio for mixedly burning Baorixile coal hasn't remarkable influence upon main steam temperature

reheated steam temperature

desuperheating water quantity for superheater and reheater

discharged flue gas temperature

and combustion in the furnace.In addition

it also hasn't bad effect on the water-wall in boiler

as well as on the coal pulverizer and the ash handling equipment etc..But

the Baorixile coal is a lignitous coal with high water content and high volatile matter content

hence

it is necessary to adopt certain mesures in aspect of explosion-proof for coal pulverizing system.
