Three Ways to Optimize Solid Fuel Combustion -

More often than not, solid fuel systems use too much under-fire air and, co-consequently, do not have an adequate fuel pile in the furnace. When this air/fuel ratio is imbalanced, combustion occurs prematurely which not only reduces efficiency potential, but can also induce damage to the furnace. As solid fuel burns, it goes through a progression.
