Current through Register Vol. 35, No. 11, June 11, 2024
Section 20.2.62.202 - DESIGN AND OPERATIONAL REQUIREMENTSA. Operational Temperature: (1) The combustion temperature as monitored at the location specified by subsection C of 20.2.62.203 NMAC shall be a minimum of 1800 degrees Fahrenheit for a 30-minute averaging period.(2) Flue gas temperature as monitored at the location specified by subsection C of 20.2.62.203 NMAC shall be a maximum of 300 degrees Fahrenheit for a 30-minute averaging period.B. Residence Time: All combustion gases shall be retained for at least 1.0 second at the required combustion temperature of subsection A or C of 20.2.62.202 NMAC at a location beyond the final secondary air injection port, or an alternative location specified by the Department if such location better represents the fully mixed height of the incinerator.C. Equivalent Design: The Department may approve a combustion unit design which does not have a minimum temperature of 1800 degrees Fahrenheit and a residence time of at least 1.0 second if it determines the proposed design will achieve a combustion efficiency equivalent to or greater than a unit meeting the requirements of paragraph (1) of subsection A of 20.2.62.202 NMAC and subsection B of 20.2.62.202 NMAC.D. Auxiliary Burner Capacity: (1) Auxiliary burners shall be installed which can supply at least 60 percent of the maximum rated heat capacity of the combustion unit.(2) Auxiliary burners shall be capable of meeting the required combustion temperature of subsection A or C of 20.2.62.202 NMAC during periods of startup, shutdown, and malfunction.E. Turndown Restriction: Municipal waste shall not be burned in an amount outside the range of 80 to 100 percent of the hourly design-rated capacity of the combustion unit.F. Automatic Waste Feed Cutoff: The municipal waste combustion unit shall include automatic waste feed cutoff mechanisms which stop waste feed to the unit if a continuous emission monitor records an exceedance of any emission limit in Table 1 (20.2.62.213 NMAC) for which compliance is based on continuous monitoring or the temperature requirements of subsection A or C of 20.2.62.202 NMAC.N.M.
