The firing and co-firing of biomass in large pulverised coal boilers

• There is a tendency for the flame produced when firing milled biomass with a topsize in the range 1- 3 mm to have the ignition plane located further out into the quarl than in a pulverised coal flame. • This is considered to be a result of the longer heating times required for the larger biomass particles compared to pulverised coal.
