Subchapter H - HAZARDOUS WASTE BURNED IN BOILERS AND INDUSTRIAL FURNACES
Section 11-266-110 - Waiver of DRE trial burn for boilers
Current through February, 2024
Boilers that operate under the special requirements of this section, and that do not burn hazardous waste containing (or derived from) EPA Hazardous Waste Nos. F020, F021, F022, F023, F026, or F027, are considered to be in conformance with the DRE standard of subsection 11-266-104(a), and a trial burn to demonstrate DRE is waived. When burning hazardous waste:
(a) A minimum of fifty percent of fuel fired to the device shall be fossil fuel, fuels derived from fossil fuel, tall oil, or, if approved by the director on a case-by-case basis, other nonhazardous fuel with combustion characteristics comparable to fossil fuel. Such fuels are termed "primary fuel" for purposes of this section. (Tall oil is a fuel derived from vegetable and rosin fatty acids.) The fifty percent primary fuel firing rate shall be determined on a total heat or mass input basis, whichever results in the greater mass feed rate of primary fuel fired;
(b) Boiler load shall not be less than forty percent. Boiler load is the ratio at any time of the total heat input to the maximum design heat input;
(c) Primary fuels and hazardous waste fuels shall have a minimum as-fired heating value of eight thousand Btu/lb, and each material fired in a burner where hazardous waste is fired must have a heating value of at least eight thousand Btu/lb, as-fired;
(d) The device shall operate in conformance with the carbon monoxide standard provided by paragraph 11-266-104(b) (1). Boilers subject to the waiver of the DRE trial burn provided by this section are not eligible for the alternative carbon monoxide standard provided by subsection 11-266-104(c);
(e) The boiler must be a watertube type boiler that does not feed fuel using a stoker or stoker type mechanism; and
(f) The hazardous waste shall be fired directly into the primary fuel flame zone of the combustion chamber with an air or steam atomization firing system, mechanical atomization system, or a rotary cup atomization system under the following conditions:
