Semi-coke is derivatives of coal

it has coal's characteristics

but there is still some difference from the coal especially in combustion performances.In order to fully grasp the combustion properties of semicoke as fuel for pulverized-coal-fired boiler

comparative analysis was carried out for more than 10 kinds of semi-coke and the raw coal.The results show that

the ignition temperature of semi-coke was lower than that of the coal with the same volatile content

and the semi-coke's ignition performance was seriously affected by the raw coal kind and was highly related to the raw coal's volatile content.Moreover

aappropriate formula of ignition temperature and simple discrimination index for semi-coke's ignition characteristics was proposed.This conclusion can provide references for design of semi-coke boiler and semi-coke blending in serviced boiler.
