Dry Sorbent Injection Systems

July 6, 2009
As pollution concerns lead to increasingly tighter regulatory standards and the need for more stringent controls at coal-fired power plants, Nol-Tec provides Sorb-N-Ject full dry sorbent injection systems for mitigating multi-pollutant emissions. Dilute-phase positive-pressure pneumatic conveying technology is used to continuously transfer dry bulk sorbent material from storage silos to injection ports on boiler flue gas ducts. The injected sorbent reacts with multi-pollutants in flue gas to reduce emissions. A fluidizing bin bottom is installed on each silo to prevent stored material from rat holing, bridging or arching. Each loss-in-weight feeder hopper is easy to calibrate and equipped with its own reverse jet-pulse dust filter system, which traps the dust generated during feeder refill and returns it to the process.
