Abstract： |
This invention relates to a method and device for using oil coke as fuel in circulation fluidized bed solving the difficulties of burned-out in burning, desulfurization and lumping, slag-bonding appearing in end flue pipe and cyclone separator in the circulation fluidized bed. This invented oil coke combined fuel includes oil coke, coal and desulfurizer which can effectively removed SO2 and eliminate lumping and slag-bonding phenomenon and big mesh sieving is applied for oil coke particles to form thicken or thin phase beds in firing chamber, suitable for subjects balance in bed; warm scuff-resistant coating is designed under the circulation fluidized bed to form high temperature zone good for firing of oil coke and burning-out, stepped burning is good for reducing NOx exhaust. |
