A New Boiler.

A new type of boiler was recently shown in operation at the works of the Road Steam Engine Company, Fmnieston, Glasgow, by the directors of the Inglis Boiler Syndicate, Ltd. During the past few months Inghs's boiler has been tested by a number of engineering experts and by Clyde engineering firms, the reports being, it is said, all satisfactory. It is a single-ended marine steel boiler, with corrugated flues, the mean diameter of the shell being

14ft. and its length lift. There are three furnaces with grates 3ft. 4 in. broad by 5 ft. 6 in. long. The return corrugated tube is 3 ft. 4 in. minimum diameter, and 8 ft. 2 \ in. long, while the tubes are z\ in. external diameter and 11 ft. long, the total number being 309. The heating surface is 47.6 times the fire-grate area, the total grate area (excluding dead-plate) aggregating 55 square feet. The total effective heating surface is 2,620 square feet.
