Current through Register Vol. 35, No. 12, June 25, 2024
Section 20.11.69.15 - DESIGN REQUIREMENTSA. All units shall be equipped with a secondary combustion chamber, which provides turbulent mixing of the secondary air with the combustion gases. The secondary combustion chamber shall provide one second of residence time, measured from the point of maximum temperature considering design-specific furnace parameters including chamber volume, volumetric airflow rate, and excess air rate.B. Primary combustion chamber temperature must be maintained at not less than 1400 degrees F.C. Secondary combustion chamber temperature must be maintained at not less than 1800 degrees F.D. Auxiliary burners must be designed to provide the required combustion chamber temperatures described in Subsections B and C of 20.11.69.17 NMAC without utilization of the heat content of the waste. The auxiliary burner fuel and the combustion air shall be controlled automatically to maintain the required temperatures.E. The charging system of any unit must be designed to prevent disruption of the combustion process. Batch charged units must be equipped with a lockout mechanism to prevent charging after start-up. Units with automatic charging systems shall be equipped with a sealed feeding device to prevent combustion upsets during charging. The loading system shall be designed to prevent overcharging.F. For batch charged units, waste shall be not ignited until the secondary chamber exit temperature is at 1800 degrees for at least fifteen minutes. Interlocks must prevent opening the charging door after ignition, until the burn-down and cool-down periods are complete.G. For continuously charged units, an interlock system must automatically stop waste feeding if: (1) the unit's secondary chamber temperature drops below 1800 degrees F for any 15-minute period; or(2) the carbon monoxide emissions, corrected to 7 percent 02 on a dry basis are equal to or greater than 50 ppm by volume, for any 15-minute period.N.M.
