Combustion Adjustments; Epa Compliance - CleaverBrooks CBEX Elite Operation And Maintenance

8.21 — Combustion Adjustments
• Humble Oil - Andok B
• Texaco - Multifak No. 2
• Phillips - 1B + RB No. 2
• Fiske Bros. - Ball Bearing Lubricant
• Standard/Mobil - Mobilux No. 2
NOTE: Siemens TEFC motors use a different grease incompatible with those listed above.
NOTE: Siemens motors contain re-greasable bearings. The shaft end (impeller end) requires the use of CB's high
temperature auto grease system (PN 884-133) for proper lubrication.
The opposite shaft end (opposite impeller) can be greased by the auto grease system or by hand pump, using two or
three pumps every three months with a grease compatible with a high temperature aluminum complex grease.
8.20.2 — Solenoid and Motorized Valves
Solenoid valves and motorized valves require no lubrication.
8.21 — Combustion Adjustments
The frequency of burner adjustments depends upon several factors, including:
• Type of burner.
• Type of fuel.
• Load conditions.
• Ambient temperature.
• Climatic variables.
• General maintenance practices.
The air-fuel ratio should be checked monthly in order to alert the operator to losses in efficiency, which do not
produce visible flame change.
Readjustment of the burner may be required due to variations in fuel composition. A combustion analyzer should
be used to adjust air-fuel ratio for maximum operating efficiency. If your burner requires adjustments, contact
your local Cleaver-Brooks authorized representative for assistance.
8.22 — EPA Compliance
In December 2012, changes were finalized to the Environmental Protection Agency's Clean Air Act standards for
Area Source boilers and Major Source boilers.* Instructions for determining your facility's Source category, as
well as your boiler's subcategory (based on boiler size, age, and fuel type) can be found on the Cleaver-Brooks
web site at http://www.cleaverbrooks.com/Reference-Center/EPA-Compliance/Index.aspx.
