Description: |
| Matthew Pitts was a Captain in His Majesty's Corps of Royal Engineers.
According to the article on boilers in the 1921 edition of Winston's Cumulative Loose-leaf Encyclopedia, "One idea which hindered advancement in boiler design for many years was that in order to generate a large quantity of steam the boiler should contain a large and compact volume of boiling water. Matthew Pitts (1793) seems to have been the first to definitely recognize the error of this belief. He found that the quantity of steam was proportional to the surface exposed to the heat. This truth indicates that as a steam generator the spherical form is the poorest, as it has the least exposed surface for a given volume. The plain cylindrical or tank boiler is the best of the early forms."
Abstract:
The improvement on the steam engine relates to the piston in the great or house cylinder, the padding or stuffing whereof, which surrounds the circumference of the piston is so contrived that as it wears away, it is extended and made to fit the cylinder without fresh padding or stuffing, or being taken out, as has hitherto been the practice, which not only occasioned great labor, but considerable loss of time. |
