Research & Development: Hydraulic WFGD Model

B&W offers wet and dry scrubbers for flue gas desulfurization (FGD). To provide our customers with superior equipment, B&W continues to develop and evaluate technologies for improving its FGD scrubber performance while also reducing the operating cost.

Hydraulic performance of wet scrubbers can be improved through design improvements that enhance flow distribution, inlet wet/dry interface, gas-liquid contacting trays, spray headers, and mist eliminators. These parameters can be evaluated and optimized methodically using the Hydraulic WFGD Model at the B&W Research Center.

As a scaled version of the commercial wet FGD design, the model properly simulates physical and fluid flow characteristics. It uses ambient air to simulate flue gas, and water to simulate the reagent slurry. The test unit has a clear acrylic plastic shell to allow visual observation and it uses a modular design for configuration flexibility and separate-effects testing.

Hydraulic model range of operation:

• Tower gas velocity - 3 to 20 ft/sec
• Liquid flux - 0 to 120 gpm/ft²
• Liquid-to-gas ratio (L/G) - 0 to 550 gpm/kacfm
• Number of trays - 1 or 2
• Number of spray levels - 1 to 6
• Mist eliminators - various full-scale designs
