Clyde Bergemann EEC UK's (CBEECUK) Spray Dryer Absorber (SDA) and Dry Injection (DI) technologies remove gaseous pollutants and heavy metals from exhaust gas stremas through the introduction of calcium, sodium and carbon based reagents to trnasform gaseous pollutants into particulate matter which can be collected downstream in a particulate collection device (ESP or Fabric Filter).

This technology is capable of removing more than 90% of acid gases from the flue gas and has demonstrated 85% removal efficiency of mercury. CBEECUK technology has been applied to the power generation, municipal solid waste and incineration markets.

Spray Dryer Absorber (SDA) Systems

CBEECUK offers SDA systems for Coal Fired Boilers and Watse Incinerators. The systems incorporate state-of-the-art SDA vessel and Fabric Filter design, direct drive-variable speed Rotary Atomisers and reagent storage and preparation systems built to our specifications. Flue gas enters the SDA system through a gas disperser located at the top of the vessel. Swirl vanes in the dispenser turn the gas counter-current to the Rotating Atomiser disk and directs it into the chamber where it comes into contact with the atomised reagent slurry. Scrubbed flue gas and entrained particulate exit through the outlet duct and are collected in the downstream particulate collector.

System Features adn Benefits

• Precise control of droplet size
• System Reliability
• Effcient mixing of gas and atomised slurry
• Rapid response to variations of gas conditions
• Consistent Performance
• Continuous operation during system maintenance with multiple atomisers

Dry Injection (DI)

CBEECUK designs and supplies Dry Injection (DI) Scrubbing Systems for the control of acid gases and other pollutants from combustion gas streams. Calcium or Sodium based reagents are introduced into the gas stream at the appropriate location to provide the desired acid gas control.
