Abstract: A provided novel colloid active component, a method for manufacturing colloid aluminum silica gel, and a surfactant containing the same are disclosed for solving water and land pollution, being safe to a human and the ecosystem, and adding economic value and applicability for the industrial use, wherein the method comprises the steps of: (a) dissolving a mixture of aluminum oxide, silicic acid, potassium, iron oxide, sulfuric acid and water into sulfuric acid; (b) adding potassium sulfate solution into the solution, and stirring at a low temperature to produce compositions with soluble aluminum double salt; (c) purifying the compositions to get very pure and dense aluminum potassium sulfate; (d) adding aluminum silicate and water to produce alkali metal polysilicate-sulfate water salt chelate; (e) polymerizing and precipitating the resultant at a low temperature to produce pectograph of aluminum silicate sieve; (f) producing chelate by adding Mgo, Fe2O3, Ca(OH)2, NaOH, KOH, and distilled water in sequence; (g

Abstract: Swirler plate in a gas burner, the swirler plate having a plurality of slits formed in a radial direction for supplying a mixed gas to a combustion chamber, and a plurality of swirl vanes formed on one side of the slits for guiding the mixed gas from the slits to the combustion chamber, including a swirl vane for a flame detector having an angle of a slope formed lower than angles of slopes of other swirl vanes, the swirl vane for a flame detector having a combustion main reaction region in which the flame detector is fitted.
