§ 58-73. Specifications for Class A incinerators.

Class A incinerators shall comply with the following requirements:

(1)

This class shall be suitable for a capacity up to 25 pounds per hour of type 1 and type 2 waste. The incinerator shall be equipped with an auxiliary burner.

(2)

These incinerators shall have a sufficient thickness of refractory lining or insulation to prevent excessive and destructive heating to adjacent materials of construction which are not a part of the incinerator. Provisions must be made for expansion to reduce or eliminate injury to building walls.

(3)

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 pounds per 1,000 pounds of flue gas, corrected to 50 percent excess air, nor shall produce smoke in excess of No. 2 on the Ringelmann chart for more than three minutes in any one hour.

(4)

They 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 walls, floors, or ceilings more than 90 degrees Fahrenheit above normal room temperature, measured at 12 inches from the incinerator exterior surfaces.
