Steam boilers

Stirling water tube steam boiler

A water tube boiler in which two, or more, upper drums and one lower drum are connected by highly inclined banks of water tubes curved so as to enter the drums radially, the upper drums being also connected by horizontal steam and water tubes.

This is a four-drum Stirling boiler with a superheater and economizer, with a chain-grate setting designed to burn coal.

The Stirling Boiler was originally built by The Stirling Consolidated Boiler Company in Baberton, Ohio, U.S.A., until 1906, when Babcock and Wilcox bought the design from them.
