MARINE REV ILE:W February, 1923 Diamond Soot Blowers for Marine Water Tube Boilers “The Best Paying Investment In the Boiler Room’’ There is a Diamond Soot blower for every type marine boiler. For water tube boilers we offer the Model G-2 M blower head illustrated on this page. This head is designed especially for marine work for operating in close quarters. It has a minimum pro- jection from the boiler casing of seven and a half inches, an especially important feature in narrow alley ways. The head covers.a very small area of the boiler casing thus avoiding interference with the doors. : Diamond soot blowers assure thorough cleaning of the boiler. When the steam jets are re- leased among the tubes, at extremely high velocity, a perfect whirlwind of currents is created, reaching all nooks and crannies of the boiler, and thoroughly removing every particle of soot and ash accumulation. From a dollars point of view, the Diamond Mechanical Soot Blower System will effect, with reference to the hand lance: 1. FUEL; a saving of 4 to 8 per cent with a consequent increase in overall boiler efficiency of 3 or 4 per cent or’ more. 2. STEAMING RADIUS; a notable increase. 3. SPEED; increase, if greater steaming capacity of boilers is utilized. 4. LONGEVITY; an increase in the length.of service of boiler tubes, through the prevention of corrosion. This is a definite statement of the results to be secured by the use of Diamond Soot Blowers. That it is an accurate statement many hundreds of marine users will testify.
