Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part V - Hazardous Wastes and Hazardous Materials › Subpart 1 - Department of Environmental Quality-Hazardous Waste › Chapter 30 - Hazardous Waste Burned in Boilers and Industrial Furnaces › Section V-3021 - Waiver of DRE Trial Burn for Boilers

Current through Register Vol. 50, No. 6, June 20, 2024
A. 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 LAC
				  33:V.3009.A, and a trial burn to demonstrate DRE is waived. When burning
				  hazardous waste:
1. 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 administrative authority 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;
2. 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;
3. 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;
4.
				  the device shall operate in conformance with the carbon monoxide standard
				  provided by LAC 33:V.3009.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 LAC 33:V.3009.C;
5. the boiler must be a watertube type boiler
				  that does not feed fuel using a stoker or stoker type mechanism; and
6. 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:
a. Viscosity. The viscosity of the hazardous
				  waste fuel as-fired shall not exceed 300 SSU;
b. Particle Size. When a high pressure air or
				  steam atomizer, low pressure atomizer, or mechanical atomizer is used, 70
				  percent of 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;
c. 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 fuel;
d. 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.
