1922 Excerpt: ...as they pass by the tubes and naturally shrink in
volume and tend to draw away from the front header, leaving a dead
space at its top. The inclined wall contracts the space as the
gases cool, so that they need every cubic inch of space to get
through and every square inch of heating surface is flooded with
hot gas. This action is continued through the second and third
passes. The result is shown in fig. 45. In another installation a
low setting had been used in connection with coal fires. Before the
existence of the new baffle was known, the bridge wall was moved
back, a horizontal shelf built and a back shot burner installed. At
the end of 54 days they had been unable at any time to develop more
than rating for the boiler, and they had lost 12 tubes. The
inclined baffle (fig. 46) was installed in a similar boiler
alongside the first as an experiment and at the end of 57 days no
tubes had been replaced and they had carried a load averaging 200%
of rating. As this meant a development of 100,000 more horsepower
per year per boiler, the first boiler was immediately rebaffled and
has since given equally good results." The application of fuel oil
burners to any type of furnace is easily performed. Fig. 47 shows
an oil burner under a vertical tubular boiler. Fig. 48 shows an
oil-burning system of Scotch Marine boilers. Fig. 49 shows an
oil-burning system applied to the Stirling water-tube boiler and
fig. 50 to a return-tubular boiler. Fig. 51 shows a Babcock and
Wilcox Oil Furnace, patented. CHIMNEY DESIGN The same procedure is
gone through in the design for stacks for oil fuel firing as for
coal burning. The required draft is the furnace at maximum overload
in each case is obtained by the necessary height and the maximum
volume of gases generated determines...
