Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 726 - STANDARDS FOR THE MANAGEMENT OF SPECIFIC HAZARDOUS WASTE AND SPECIFIC TYPES OF HAZARDOUS WASTE MANAGEMENT FACILITIES › Subpart H - HAZARDOUS WASTE BURNED IN BOILERS AND INDUSTRIAL FURNACES › Section 726.210 - Waiver of DRE Trial Burn for Boilers

Current through Register Vol. 48, No. 28, July 12, 2024
Boilers that operate under the special requirements of this
				  Section, and that do not burn hazardous waste containing (or derived from)
				  USEPA hazardous waste numbers F020, F021, F022, F023, F026, or F027, are
				  considered to be in conformance with the DRE standard of Section
				  726.204(a),
				  and a trial burn to demonstrate DRE is waived. When burning hazardous
				  waste:
a) A minimum of 50 percent of
				fuel fired to the devices must be fossil fuel, fuels derived from fossil fuel,
				tall oil, or, if approved by the Agency 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 50 percent primary
				fuel firing rate must 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 must not be
				less than 40 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
				must have a minimum as-fired heating value of 8,000 Btu/lb, and each material
				fired in a burner where hazardous waste is fired must have a heating value of
				at least 8,000 Btu/lb, as fired;
d)
				The device must operate in conformance with the CO standard provided by Section
				726.204(b)(1).
				Boilers subject to the waiver of the DRE trial burn provided by this Section
				are not eligible for the alternative CO standard provided by Section
				726.204(c);
e) The boiler must be a water tube type
				boiler that does not feed fuel using a stoker or stoker type mechanism;
				and
f) The hazardous waste must 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:
1) Viscosity. The viscosity of the hazardous
				waste fuel as fired must not exceed 300 SSU;
2) Particle size. When a high pressure air or
				steam atomizer, low pressure atomizer or mechanical atomizer is used, 70
				percent of the the hazardous waste fuel must pass through a 200 mesh (74
				micron) screen, and when a rotary cup atomizer is used, 70 percent of the
				hazardous waste must pass through a 100 mesh (150 micron) screen;
3) Mechanical atomization systems. Fuel
				pressure within a mechanical atomization system and fuel flow rate must be
				maintained within the design range taking into account the viscosity and
				volatility of the fuel;
4) Rotary
				cup atomization systems. Fuel flow rate through a rotary cup atomization system
				must be maintained within the design range taking into account the viscosity
				and volatility of the fuel.
