Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-266 - Disposal Standards › Section 3745-266-110 - Waiver of destruction and removal efficiency trial burn for boilers

Current through all regulations passed and filed through July 1, 2024
Boilers that operate under the special requirements of this
				rule, and that do not burn hazardous waste containing (or derived from) EPA
				hazardous waste numbers F020, F021, F022, F023, F026, or F027, are considered
				to be in conformance with the destruction and removal efficiency (DRE) standard
				of paragraph (A) of rule
				3745-266-104
				of the Administrative Code, and a trial burn to demonstrate DRE is waived. When
				burning hazardous waste:
(A) A
			 minimum of fifty per cent of fuel fired to the device must 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 rule. (Tall oil is a fuel derived from vegetable and rosin fatty acids.)
			 The fifty per cent 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 forty per cent. 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 eight thousand Btu per pound, and
			 each material fired in a burner where hazardous waste is fired must have a
			 heating value of at least eight thousand Btu per pound, as-fired;
(D) The device must operate in conformance
			 with the carbon monoxide standard provided by paragraph (B)(1) of rule
			 3745-266-104
			 of the Administrative Code. Boilers subject to the waiver of the DRE trial burn
			 provided by this rule are not eligible for the alternative carbon monoxide
			 standard provided by paragraph (C) of rule
			 3745-266-104
			 of the Administrative Code;
(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 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 three hundred
			 SSU;
(2) Particle size. When a high
			 pressure air or steam atomizer, low pressure atomizer, or mechanical atomizer
			 is used, seventy per cent 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 per cent of the hazardous waste must pass through a one hundred
			 mesh (one hundred fifty 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.
