Referring also to page 33 for information relating to the burning of
sawdust and shavings S. S. Ingham, _in the Stationary Engineer_, says
upon this important matter:
“Regarding a furnace for burning sawdust, I submit the accompanying
cuts. I have built numbers of these oven furnaces for burning this fuel
in the south, and all have given excellent results. The dimensions
are for 60″ × 16′ return tubular (4″ tubes) boiler with stack 50 per
cent. greater area than the flues; a good draft is necessary.” It will
be understood that the upper cut is designed to show end view of the
furnace whose side is shown in sectional view at the bottom of the page.
