Burner Application Details Packaged Versions

Transcription

1 Packaged & BMV CYCOMAX Burners Page 83 Packaged Versions CYCOMAX Burners were designed for low to moderate temperature oven-type applications only. They may be used in any oven whose combustion chamber temperature is 8 F (47 C) or less. NOT: CYCOMAX Burners should not be used in any application where there is a static (no moving air) condition. Packaged CYCOMAX Burners include a low horsepower combustion air blower in your choice of the voltages listed below. Packaged C YCOMAX Burner Model Horsepower.4M.8M.6M.7M 3.7M / / 3/ /46/3/6 / / 3/4 3 7/3/6 / / 3/4 3 IMPOTANT: The combustion air blower must be in operation any time the air stream temperature is above F (93 C). If not, damage to the blower, burner and piping is possible. To adjust the Packaged burner, set the gas pressure according to the values shown in the table below. During adjustment, observe the flame if possible. The flame should be blue and it should be totally contained inside the combustion sleeve, especially at low firing rates. Blue flame outside of the combustion sleeve is caused by combustion that is either too rich or too lean and will result in high levels of CO. Yellow or orange flames are normally an indicator of a too-rich flame. Higher oven suction will require higher gas pressure to the burner for optimum performance. Higher back pressure will require less gas pressure to the burner for optimum performance. The values listed in the table below are for a near balanced condition. IMPOTANT: The pilot must be interrupted in order to obtain the emissions listed in the following table. Continuous pilot is not recommended.

2 Page 84 Packaged & BMV CYCOMAX Burners BMV Versions Maxon CYCOMAX Burners are available in four external blower versions. By using the specified external blower, it is possible to double the capacity of the burner over the Packaged version. missions are similar to the burner operating with a packaged fan. With the BMV versions, there is slightly more flame outside of the can and this makes the burner more sensitive to cross velocity. The external blower versions are very similar to the packaged versions except they do not include gas or air internal control devices. A threaded B Air Adapter allows the MICO-ATIO Valve to be mounted. The recommended (minimum) FG Blower is shown in the chart below. If you use a butterfly style gas valve on the MICO-ATIO Valve, turndown could be affected. Poppet style gas valves should be used. If your air piping is unusually long and/or contains many fittings, please review your blower size to compensate for higher pressure drops through the air piping. Set the MICO-ATIO Valve to obtain the gas and air pressures shown on the graphs on pages The following table lists the recommended MICO-ATIO Valve and FG Blower selections. The values in the table below are guidelines. To meet your capacity and turndown needs, pressures must be set to match the graphs on pages IMPOTANT: The BMV versions, like the packaged versions, should be operated with interrupted pilot. missions can be % higher if the pilot is left on continuously and combustion sleeve life is reduced. IMPOTANT: Whenever the combustion chamber temperature is above F (93 C), air should be flowing through the burner. If not, damage to gaskets in the burner could result and increase the chance for leaks.

NOT: Operation above the recommended gas pressure for a given air pressure will result in higher NOx and lower CO. Operation below the recommended gas pressure curves will result in lower NOx and higher CO. Use of propane as a fuel will result in higher emissions. Oven cross velocities and back pressures have a slight affect on the optimum pressures to set.
