Current through June, 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 § 266.104(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 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 50 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 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 shall 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 shall
					 operate in conformance with the carbon monoxide standard provided by §
					 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 § 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:
(1) Viscosity. The viscosity of the hazardous
					 waste fuel as-fired shall not exceed 300 SSU;
(2) Particle size. When a high pressure air
					 or steam atomizer, low pressure atomizer, or mechanical atomizer is used, 70%
					 of the hazardous waste fuel must pass through a 200 mesh (74 micron) screen,
					 and when a rotary cup atomizer is used, 70% 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 shall 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.
