Specifications for Class B incinerators.
Jackson Code of Ordinances § 58-74
in effectSec. 58-74. - Specifications for Class B incinerators.
Class B incinerators shall comply with the following requirements:
(1) This class is suitable for capacities up to, but not including, 100 pounds per hour of type 1 and type 2 waste. The incinerator shall be equipped with an auxiliary burner.
(2) These incinerators shall be so designed that when operated according to the manufacturer's instructions they shall not emit fly ash in excess of 0.80 pound per 1,000 pounds of flue gas, corrected to 50 percent excess air, nor shall they produce smoke in excess of No. 2 on the Ringelmann chart for more than three minutes in any hour. The design shall be such that when the incinerator is fired with shredded newspaper at its rated capacity, in pounds per hour of type 2 waste, it shall not have a surface temperature at any point in excess of 160 degrees Fahrenheit above room temperature after continuous firing for three hours. The only exception to this maximum temperature shall be at the surface of the doors and frames or at the breaching outlet. The minimum acceptable construction of the incinerator shall be No. 16 gauge steel exterior casing, one inch thickness of high temperature block insulation and a two-inch thickness of high heat duty firebrick or a two-inch thickness of castable, or plastic refractory. The castable or plastic must be properly anchored to the exterior steel casing.
(3) These incinerators must be constructed to withstand intermittent internal temperatures as high as 1,800 degrees Fahrenheit without cracking, warping, or other failure of structural parts in such manner as to permit flame passage or emission of combustion gases or sparks to the exterior. The design shall be such that when installed in accordance with the manufacturer's directions and specified clearances, the continued operation of the unit at maximum burning rate of shredded newspaper for a period of at least one hour will not raise the temperature of surrounding combustible walls, floors, or ceilings more than 90 degrees Fahrenheit above normal room temperatures, measured at 12 inches from the incinerator exterior surfaces.
(4) Total heat release in the entire incinerator, excluding ash pit, shall be not more than 25,000 Btu's per cubic foot per hour.
