Power is one of the largest items of expense in the cost of operating a vessel, and the cost of fuel represents on the average 70 per cent. of the cost of power. The presence of soot has cost—it still costs—a loss of hundreds of thousands of tons of coal and hundreds of thousands of barrels of fuel oil a year to ship owners. Soot waste has been eliminated on many ships, and it can be eliminated on all with a consequent notable increase in boiler efficiency and a consequent great increase in marine profits. There is a Diamand Soot Blower for every marine boiler—rear and front end types for Scotch boilers, hollow stay bolt type for water tube ON boilers with hollow stays, revolving unit systems < meet A CoP for vertically baffled water tube boilers. The sei Diamond Company is the pioneer soot blower manufacturer in the marine field. Its blowers today represent the best fruits of twenty years practical experience.
