Webster Combustion

Webster Combustion

Campbell-Sevey teams up with Webster Combustion as they are a leading manufacturer of custom and semi-custom multi-fuel boiler burners for the commercial, institutional and industrial markets.

Webster Combustion Burners

Webster’s high efficiency, low excess air burners incorporate a unique high swirl firing head to improve commercial boiler combustion efficiency. Coupled with a highly efficient in-line combustion air fan which provides superior mixing of the fuel and air, the burners require lower boiler horsepower, therefore using less fuel and electricity than conventional burners. The combination allows the burner to operate with low excess air across a large operating range resulting in significant energy savings with short payback.

TEMP-A-TRIM® Air Density Trim System Saves Money

Webster Combustion’s patented TEMP-A-TRIM® air density trim system senses combustion air temperature and automatically varies the fan speed to create a constant mass air flow for combustion. By maintaining optimum fuel/air ratios, TEMP-A-TRIM® ensures maximum burner efficiency. As a result, TEMP-A-TRIM® pays for itself in the following ways:

  • Up to 3% savings on fuel bills
  • Up to 30% savings on electrical bills
  • Up to 2% in boiler efficiency gains
  • Reduced maintenance costs
TEMP-A-TRIM® Features & Benefits:
  • Reduces the need for seasonal burner tuning
  • Feed-forward control for accurate operation
  • Easy to install with no special set-up required
  • Compatible with linkage or linkageless controls
  • Precisely corrects for changes in air density to automatically optimize combustion efficiency

The air temperature in a typical boiler room can change dramatically, causing significant combustion inefficiencies and degrade stability, driving up the cost of fuel and utilities. Temp-A-Trim® resolves that automatically!

FDR Series Multi-Fuel Windbox Register Burners

The FDR Forced Draft Register burner is a highly efficient combustion system that combines a windbox, air register, ignitor assembly, fuel train, flame safety control, combustion control and forced draft blower all assembled into one complete package.
