UNITED strArEs PA rEN'r OFFICE- GEORGE W.
WALLACE, OF EAST ST. LOUIS, ILLINOIS, ASSIGNOR TO HALENE PRODUCTS (30., OF ST. LOUIS, MISSOURI, A CORPORATION OF DELAWARE.
BOILER-OLEANING COMPOSITION.
No Drawing.
T 0 all whom it may concern Be it known that I, Gnoncn WV. WALLACE, a citizen of the United States, residing at East St. Louis, Illinois, have invented a certain new and useful Improvement in Boiler-Cleaning Compositions, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains, to make and use the same.
This invention relates to substances that are used for removing scale from boilers,
and has for its main object to provide a' new composition of matter that will effectively remove boiler scale and also prevent scale from forming in the boiler without danger of injuring the boiler.
The boiler compounds or compositions that are now used for removing scale from boilers contemplate the removal of the scale by decomposing the insoluble scale-forming salts into soluble compounds. Such compositions are composed principally of strong solvents, and while they succeed in removing the scale, they usually injure and frequently ruin the boiler in which they are used, by reason of the solvents attacking the iron from which the boiler is formed.
My improved composition difiers from the compositions that have heretofore been used for cleaning boilers in that it contains a substance that will disintegrate the scale without having any injurious effect on the iron of the boiler. It is also distinguished from prior boiler-cleaning compounds because it destroys the adhesive properties in the scale-forming salts in the water in the boiler and prevents said salts from combining or forming a scale when they are precipitated.
Briefly described, my improved boilercleaning composition consists of a saturated solution of naphthalene in hydrocarbon oil. Any suitable hydrocarbon oil may be used, but I prefer to use an oil of low specific gravity. Gasolene or naphtha may be used successfully, but I have obtained the best results from hydrocarbon oil of the benzin series, namely, toluene or Xylene, In pro- Specification of Letters Patent.
Application filed July 19, 1915.
Patented May 16, 1916.
Serial No. 40,650.
ducing the composition I simply dissolve naphthalene in hydrocarbon oil so as to form a saturated solution, and in using the composition I simply introduce it into the boiler with the feed water that is supplied to the boiler. If the inside of the boiler is dirty or coated with scale, the composition attacks the scale and disintegrates it or breaks it up into line particles by the chemical reaction of the naphthalene on the substances in the scale, which cause the particles of the scale to adhere to each other and to the iron of the boiler, the hydrocarbon oil on account of its capillary affinity penetrating into the interstices of the scale, and thus causing the naphthalene to be thoroughly distributed through the scale. In other words, the composition breaks up the scale by destroying the adhesion between the particles of scale-forming salts and between saidparticles and the surface of the boiler on which they'are deposited. In addition to breaking up the scale, my improved composition causes the scale-forming salts in the water in the boiler to become so thoroughly saturated or coated with the naphthalene that the salts will not combine and form a scale when they are precipitated.
A boiler-cleaning composition of the character above described has no injurious effect whatever on the boiler in which it is used, owing to the fact that it does not contain a strong solvent or ingredient that is injurious to iron. It merely consists of naphthalene and another ingredient that acts as a vehicle to carry the naphthalene into the pores of the scale and also to disseminate, or thoroughly distribute, the naphthalene through the feed water that carries the composition into the boiler.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is:
1. A boiler-cleaning composition composed of naphthalene and a substance of great capillary affinity.
2. A boiler-cleaning composition consisting of a saturated solution of naphthalene in hydrocarbon oil.
8. A boiler-cleaning composition consistsignature in the presence of two Witnesses, ing of naphthalene and hydrocarbon oil of this sixteenth day of July, 1915. low specific gravity.
