ABSTRACT:
This invention relates to a calibrated oil burner filter paper on which is imprinted or otherwise processed a pre-selected geometrically shaped standard gray smoke scale and its integral use with an oil burner smoke tester and dispenser to provide a paper record for a quick and accurate visual analysis of the smoke density of a test smoke spot of the flue gases from burning distillate fuels, and also in the subsequent determination of the "Smoke Spot Number" of the flue gases by visually matching the shade of the test smoke spot lying in juxtaposition with the most like shade of a sector of the said imprint of a pre-selected shaped standard smoke test scale.
