Current through Register 2024 Notice Reg. 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) US
					 EPA Hazardous Waste Nos. F020, F021, F022, F023, F026, or F027, are considered
					 to be in conformance with the DRE standard of section
					 66266.104(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 shall 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 section
				  66266.104(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
				  section 66266.104(c);
(e) The boiler shall 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 shall pass through a 200 mesh (74 micron) screen,
				  and when a rotary cup atomizer is used, 70% of the hazardous waste shall 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
				  shall be maintained within the design range taking into account the viscosity
				  and volatility of the fuel.
