George Edwards' Scrapbook Toiler cleaned cleaner BY DOWELL SERVICE Chemical solvents, removed 1650 lb. of deposits from boiler previously "cleaned" by turbining Our local power company put in electrostatic pre cipitators lost month to keep our town from being showered with flyash. Back in my kid days factory owners prided themselves on the amount of smoke their slacks belched into the sky. I'm told dust particles often reached several million to the cubic foot. Makes me think of the ancient Greeks amusing their friends by rubbing silk with amber to create static electricity to the amber would attract straw.

I see where J G Chapman of.Duke Power Co built a portable power plant. He uses it to prevent costly shutdowns when changing or replac ing conductors, transformers, ond other line and sub-station equipment. Total weight is 25,000 lb. It's a standard Fruehauf trailer with a war surplus P-51 (air plane) liquid-cooled (Cljrcol) Allison en gine, of 1150 fip. Rating Is 500 kw, 80% power factor. Complete unit cost $22,000, has been used 15 times in past three years. Last time I was in New York, teems Ben Skrotski on Power suggested that public utilities build large mobile units. His idea was to have them on hand to supply power at any trouble spots in an enemy attack on this country. Wonder what happened to thnt scheme? America has furnished to the world the characier ef Washington, and if our American institutions had done nothing else, that alone would havo entitled them to the respect of mankind. "-Daniel Webster 104 A compressor manufacturer I know has been building what he calls a "new kind of centrifugal . pump" for the past few years. Said his staff has been so busy making the thing work right they haven't had time to do much research. I told him to write the Office of Technical Service, Dept of Commerce, Washington 25, D.C. They stockpile about 2SOJDOO technical reports that have ' never been published in scientific or technical jour nail. *`Those government people are not only glad to send you anything they hove on pumps," f told him, "bui they are even glad to give you technical' advice My motto has altoays been to know what others have done before I go stubbing my toe in the dark.

' Where mechanical devices, rattling, and turbining Jr-; fail to clean--in crevices, around angles, through 1 openings--Dowell solvents are designed to dissolve and loosen scale ond sludge . . . carry away these ! profit-stealing deposits quickly and easily. ?For example, Dowell recently cleaned a 150,000 pphr ' boiler that had previously been turbine-cleaned. 1 Although the chemical cleaning required only s few fij*. .`hours, Dowell engineers removed 1,650 additional J' pounds of deposits from the boiler. Beat of all, no scaffolding or dismantling of equipment was necessary. Dowell-designed equipment was used to introduce special liquid solvents through regular connections. Downtime was kept to o minimum. What is your cleaning problem? Dowell has extensive experience in cleaning all kinds of process and heat exchange equipment.
