354 Heating Systems COLUMBIA Boiler Company of Pottstown Pottstown, Pa. Makers of steel power and heating boilers COLUMBIA'S H.R.T.* OIL OR GAS FIRED BOILER & STEAM GENERATOR ASHE CODE CONSTRUCTED Available for pressures of 15 to 250 psi A complete, automatic power plant wherever steam is used for processing Columbia b.r.t. boilers are fully automatic, compact, complete steam generators. Available in sizes ranging from 2 to 100 horsepower. Designed for firing with gas, light or heavy oils. A special Columbia unit makes pos sible the inter-changeable use of gas or oil. Overfiring Permitted: Conservative ratings plus large combustion volume permit overfiring. This frequently eliminates the need for additional boiler capacity, al lows for plant expansion. High Steam Output: Columbia's h.r.t. boilers have an unusually large heating surface to produce more steam at higher efficiencies. More heat is converted into steam since it is proportioned to make maximum use of hot gases of combustion for the production of steam. Horizontal Design for longer life: The complete sub mersion of tubes protects them from water line cor rosion. Dry Steam Assured: Large steam space and greater liberation area virtually eliminate waste producing water carryover. Over-AU Efficiency: Factory installed, specially de signed combustion chamber provides rapid heating re fractory surfaces for peak combustion efficiency. In sulation, 7 inches thick in the combustion chamber proper, and 4 inches thick in the gas passage, keeps heat loss at a minimum. Special refractory brick heats up to great intensity to complete the combustion of previously unignited fuel particles. This complete com bustion not only increases efficiency but makes for clean combustion. Soot accumulation on heating sur faces is minimized. Boiler tubes require less cleaning. Safety Assured: Two pass updraft design lowers direct loss and reduces possibility of furnace pressure, pulsation or excessive combustion noises. Accessibility and easy Maintenance: Simplified con struction provides easy front and back access to the single bank o! tubes. Entire unit can be gotten to for inspection of boiler and chamber by removing the covers.

COLUMBIA Boiler Company of Pottstown Pottstown, Pa. Makers of steel power and heating boilers STEEL, TUBELESS, OIL-FIRED, WATER TUBE GAS-FIRED AND COAL-FIRED HEATING UNITS 355 ASME CODE CONSTRUCTED SBI RATED A.G.A. APPROVED Available with highly efficient, custom_engineered gas or oil burners. Columbia steel boilers, gas or oil fired, have self contained large copper instantaneous tank less coils, supplying a continuous flow of year 'round domestic hot water. . Maximum operating efficiencies assured by the bal anced design of the boiler and burner; by the arrange ment of the baffles which force the hot gases to travel four or five times the full length of the boiler. One piece electric welded construction: Columbia offers a heating unit with full electric welded construc tion of heavy copper bearing steel, to assure lower heat ing cost and longer operating life. Quiet operation: Ample combustion space, the insula tion and heavy steel jacket completely eliminate objectional noise. Dual Firing: Columbia oil heating units may be easily converted for efficient gas firing. Oil and gas burners for Columbia Boilers are designed and manufactured by Columbia to insure maximum perforraance of boiler-burnerjmits and to provide undivided responsibility. MODEL NO.
