Turbine, Fresh Air Fan Systems, Blowers and Dampers

Fact: Without an operational turbine or fresh air fan system providing combustion air, the burner(s) CANNOT be operated.

• Is the turbine and/or fan operational?
• If not, when will the turbine and/or fan become operational?
• If applicable, are all blowers, dampers, and diverters operational?

Field Wiring

• Has wiring between all Coen furnished electrical enclosures completes as shown on Coen's Wiring Schematic Diagrams?
• Are all damper and diverter position switches wired to Coen supplied control enclosures per Coen Wiring Schematic
  Diagrams?
• Are all "ship loose" items (See Coen Bill of Materials) wired per Coen's Wiring Schematic Diagrams?
• Has all wiring to Coen control enclosures been reviewed to verify that all contact requirements have been satisfied?

Fluid Systems

Fact: Field installed interconnecting piping between Coen furnished equipment is often filled with debris. The debris will not only delay the start-up, but will also clog burner orifices and damage valve seats and seals.

• Prior to connecting process lines to Coen equipment, were all fuel, air and steam lines cleansed of all debris?
• If purging of the gas lines require certification, had certification been obtained?
• Are strainers provided upstream of Coen furnished piping to prevent entry of foreign materials into fuel control valves, safety devices and burner components?
• If the burner required atomizing steam, is the steam line trapped to atmosphere assuring a dry steam source?
• Have drip legs been installed upstream and downstream of the Coen Piping Module to trap and drain turbine exhaust
  condensate in all lines prior to firing the burner?
  

Control Systems

• If applicable, is a programmable logic controller (PLC) field terminal available on site?
• If not, should Coen provide a terminal?
  

Testing

• Are flow measuring devices provided and operable to determine capacity of either the burner or the fired vessel?
• have the provisions been made for full load testing or venting?
• Is there an ample fuel supply to operate the burner and pilot(s)?
  

Are qualified operators available for start-up?
