Pollutant Control Systems
Dry Sorbent Injection (DSI) and Activated Carbon Injection (ACI) technology are usually installed either before or after the air preheater. Dry sorbents can be injected to remove targeted pollutants, including SO2, SO3, HCI and mercury, allowing for customised regulatory compliance strategies.
We uniquely utilise CFD as a tool to optimise the design of the injection system and evaluate a wide variety of injection options to reduce overall CAPEX and OPEX for the customer.
In order to optimise a sorbent injection system, a CFD model is used as a cost-effective tool to assist in the design of the system and lance configuration. CFD models provide detailed information on flue gas flow, flue gas temperature, sorbent dispersion in duct, location of reaction, and optimisation of lance locations and positioning for maximum sorbent dispersion. The enhanced dispersion yields better sorbent utilisation, resulting in higher reduction capabilities and lower sorbent consumption.
