Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 266 - HAZARDOUS WASTE MANAGEMENT STANDARDS FOR THE MANAGEMENT OF SPECIFIC HAZARDOUS WASTE AND SPECIFIC TYPES OF HAZARDOUS WASTE MANAGEMENT FACILITIES › Subchapter H - HAZARDOUS WASTE BURNED IN BOILERS AND INDUSTRIAL FURNACES › Section 11-266-110 - Waiver of DRE trial burn for boilers

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 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:
(1) Viscosity. The
				  viscosity of the hazardous waste fuel as-fired shall not exceed three-hundred
				  SSU;
(2) Particle size. When a high
				  pressure air or steam atomizer, low pressure atomizer, or mechanical atomizer
				  is used, seventy percent of the hazardous waste fuel must pass through a
				  two-hundred mesh (seventy-four micron) screen, and when a rotary cup atomizer
				  is used, seventy percent of the hazardous waste must pass through a one-hundred
				  mesh (one-hundred and fifty 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.
