The prediction of burning behavior for Shenhua blended coal and Fudong 21 coal in the laboratory

as well as the state of test in practical combustion on 1025 t/h boiler of Jiaxing Power Plant have been presented. Results of sedimendation furnace and thermal balance analysis show that the ignition and burn away behavior of the two said coal sorts are similar

whereas based on prediction of slagging behavior in the sedimendation furnace

the slagging tendency of both said coal sorts is similar under temperature of 1350℃

all having a medium and somewhat stronger slagging tendency. But along with reduction of the temperature the slagging tendency of Fudong 21 coal is fastly decreasing

however the slagging behavior of Shenhua blended coal is slowly decreasing. The results of comparison test under hot state on practical boiler are basically similar to the prediction in laboratory.
