Abstract
A process of treating the interior steel walls and gas and/or air moving fans or blowers in electrical precipitation installations with a material containing micro micron sized particles of graphite in a liquid carrier is described that forms a penetrating lubricating adhesive coating on the interior walls and fan blades and blower parts of the electrical precipitation installations and which acts to prevent the accumulation of coal, tar, dust, fly ash and other particles thereon.
Claims5
A process of treating the inner steel walls and fluid handling and moving devices in electrical precipitation installations that consists essentially of the steps of cleaning said steel walls and devices, penetrating a liquid suspension of micro micron particles of graphite into said cleaned steel walls and devices so as to build up a smooth adhering and lubricating coating on said steel walls and devices, said suspension including substantially between about 5% to 25% micro micron particles of graphite by weight, between about 34% to 75% by weight of a solution of water and sodium silicate, with the sodium silicate present at about 40% of the solution, between about 2% to 10% by weight concentrated hydrochloric acid, between about 33% and 75% by weight of a solution of water and carboxy vinyl polymer resin wherein the resin is present in amounts between about 1% to 10% of the solution and between about 15% to 20% by weight water and drying said coating to form a slick smooth surface.
