The equipment that described employing fluid bed suspension boiler burns saliferous mud also comprises:
Fluid bed suspension boiler 1, taking conduction oil as heat transfer medium;
Wherein, described automatic ration proportioner 2, feed arrangement 3, slurry transportation system 5, fluid bed suspension boiler 1 connect successively.
Preferably, described equipment also comprises dust arrester 11, and the flue gas producing after burning is discharged and passed through described dust arrester 11 and collect disposal, meets environmental requirement.
Preferably, described equipment also comprises energy collecting system 10, the heat recycling of described energy collecting system 10 for sludge incineration is produced.
Preferably, between described automatic ration proportioner 2 and described feed arrangement 3, be provided with pelletizer 4.
Adopt this equipment to mix and burn coal slime and burn described technique and comprise the following steps saliferous mud:
S1: detect saliferous mud chlorinity and determine the slime content that need mix burning, make mixed feeding chlorinity lower than 0.3%, mix the ratio of burning coal slime and determine according to actual chlorinty, when industrial sludge burns, coal slime mixed-fuel burning proportion is 30～40%;
S2: saliferous mud-coal slime slurry, under the high-speed air flow effect of 30～40m/s left and right, in fluid bed suspension boiler, be stable gas-solid fluidized state, carry out fluidized bed combustion;
S3: the heat collection recycling that sludge incineration is produced;
