Low NOx Burners

Low NOX Burners & Over Fire Air

10,000 MW OF SUCCESSFUL INSTALLATIONS

Power & Industrial Services’ experience in manufacturing replacement burners for all OEM’s has given P&I a unique perspective to thoroughly evaluate many different designs and methods of construction. This has given P&I an insight into what will perform reliably in the harsh environment of a coal fired boiler.

Every P&I LNB & OFA Project has Exceeded Guarantees.

Burners & Components

P&I In-House Expertise

P&I is the only Low NOX Burner supplier that engineers, designs and manufacturers all of the burners and components in their own shop assuring quality control and on-time delivery.


Maintenance FREE Operation

DESIGNED & CONSTRUCTED, YEARS OF MAINTENANCE FREE OPERATION

•Rugged design gives superior performance and adjustability during start-up and allows for easy re-tuning year after year to adjust for coal changes and boiler performance requirements

•No other burner manufacturer puts more emphasis on the use of superior heat-resistant materials such as PI-2000, 253MA and 309 stainless steel


Burner Tuning Features


Unit Review

•Coal and boiler operating data review

•Test data review

•CFD modeling of air flow and chemical species of combustion

•3D Solidworks models of the combustion system is made after field measurements. This helps with mechanical design and reducing installation problems

CUSTOM DESIGNS

•Once the baseline CFD model is completed, the addition of Low NOX , burners with and without Over Fire Air can be tested

•Elevation changes of the OFA can be tested as well as various mill and burner combinations and operating conditions


Design Review

CFD MODELING

•Assists in predicting the flame shape by running multiple register and spin vane settings

•Helps quantify the amount of secondary air to each burner by running multiple windbox pressure settings

•Assists in predicting fuel distribution and how it affects burner performance
