The AH-MA design provides stable operation over a wide range of velocities, inputs, and fuels. AH-MA v2.10 burners are line type burners constructed of cast iron or aluminum burner bodies and diverging stainless steel air wings.

- Page 11 ) From the “Operating Range” chart in Data Sheet No. 160, the maximum heat input at 0.7"w.c. air pressure drop is 800,000 Btu/hr/ft. The flame length from the “Flame Length” chart in Data Sheet No. 160 is 30". Burner length, feet = 6, 40,000 Btu/hr = 7.8 feet; round up to 8 feet. 800,000 Btu/hr/ft 3) Minimum: Btu/hr = 1.3 X 60,000 X 5 = 390,000 Btu/hr.

- Page 21 The pilot fuel is fed into the pilot end casting which is separate from the main fuel. A pilot adjusting valve is required to adjust the pilot gas flow (Eclipse part number 12659 is recommended). The needed pilot capacity is 20,000 Btu/ hr, but the pilot will operate equally well at higher or lower inputs.
- Page 22 Eclipse Combustion recommends the use of flame monitoring control systems which maintain a spark for the entire trial for ignition time when using U.V . scanners.
- Page 23 tep 5: Gas Valve T rain Selection igures 3.9 and 3.10 illustrate gas valve trains for single and staged burner systems respectively. The typical main gas valve train for a staged burner has the same valve layout as a single burner except each burner has an individual sole- noid valve to independently shut down each section.
