Bigelow Two-Pass Boilers used for healing the new Home Office Building of The Hartford' Steam Boiler Inspection and Insurance Co., the largest insurer of steam boilers in the United States Since 1S60 it has been the endeavor of The Bigelow Company to merit a reputation for constructing boilers of a high standard of design, workmanship and material. We are proud of the confidence shown in us by the use of Bigelow boilers in this building. . The Bigelow Two-Pass Boiler is designed to meet heating and power requirements, especially where space limitations prevail. It contains the recognized features of the well-known H.R.T. boiler, but due to the small amount of brickwork required it can be in stalled at a lower complete cost. The elimination of special brick shapes and staybolts in the furnace reduces the cost of maintenance to a minimum: Other features of importance are large furnace volume, long gas travel, uniform velocity of gas over heating surface and low exit temperature, all of which assure a maxi mum efficiency. Bigelow Two-Pass Boilers are constructed in standard sizes from 25 H. P. to 200 H. P. and for working pressures of 15 pounds and 125 pounds. 660 Boilers, Steel E. Keeler Company Williamsport, Pa. Established 1864 Riveted Steel Boilers For Heating and Power Steel Stacks, Breechings and Plate Fabrications Keeler Double Duty Boiler The Keeler Double Duty Boiler is designed for heating or power purposes. It may be set singly or in battery and fired by hand, stokers, oil, or gas. The construction eliminates curved crown sheets requiring radial stays, flat sides with braces between tubes and staybolted side furnace walls, thus internal cleaning is simplified and lower main tenance costs are obtained. The use of a refractory lining and the large furnace volume results in highest possible efficiencies. The tables below show floor space re quired is the minimum. Keeler Type "J" Watertube The Keeler Type "J" .Water ;Tube Boiler.is designed especially for installation in boiler rooms where both floor space arid ceiling height are limited. Less space is required for replacement of tubes than any other design of high pressure water tube boiler. The Keeler Straight Tube Cross Drum Water Tube Boiler is recognized as a lead ing high pressure boiler in school and office building heating plants.
