The high alkali coal is a kind of fine power coal which is easy to ignite and easy to burn out
while it has serious slagging and fouling characteristics. The on-service boilers are suggested only to be blended with high alkali coal in a certain proportion
so the boilers' adaptability to the high alkali coal is limit. Aiming at burning pure high alkali coal
the integrated design idea for newly built 660 MW units was proposed
and the values setting of the boiler key load parameters
the reasonable heating surface arrangement
the burner design
the selection of deslagging equipment and air pre-heater were given
to provide a reference for design of the boilers burning high alkali coal.
