For over half a century sugar mills and refineries throughout the world have chosen BABCOCK boilers, fired with conventional fuels such as oil, gas, coal and wood, or with bagasse and other vegetable-refuse fuels, to meet their steam-raising requirements with the utmost reliability, economy and ease of maintenance. This long and specialised experience is combined with modern design and construction in various types of Babcock boiler plant, with a wide choice of firing equipment to meet local requirements-the versatile Babcock-Detroit spreader stoker, burning bagasse and a variety of other fuels; the widely-used Babcock-Ward bagasse-furnace for efficient combustion and low maintenance and the established Horseshoe and Step-grate furnaces - with auxiliary oil or gas firing, if required.
