Abstract
A small-scale scrapped tire boiler system for heating a small-scale facility using heat generated by burning scrapped tires. The system includes a scrapped tire burner furnace, a heat exchanger for heating a cool heat transfer medium from the facility by the combustion gas from the furnace and supplying the heated medium to the facility, and an exhaust gas purifier for purifying sulfurous acid gas and carbon dust contained in exhaust gas. The purifier includes an exhaust gas tower having a vertical path to discharge the combustion gas, a water sprayer for spraying water from the upper side of the tower so that the sulfurous acid gas is made to melt to water and the carbon dust is made to adsorb to fall down, a neutralizer for precipitating sulfurous acid gas components into alkali salts in a sulfurous acid aqueous solution to thereby neutralize water, and a tank containing the solution and water. The precipitated alkali salts are removed from the bottom of the tank and the floating carbon dust is removed from the upper portion of the tank.
