Perfect as a “pollutant trim” solution, furnace sorbent injection adds a huge operating cost decrease because it involves injecting finely ground limestone particles (sometimes 1/10 of the price of other sorbents) directly into the boiler for acid gas reduction.
Furnace sorbent injection is a very temperature-sensitive process that requires good distribution and placement of the sorbent to maximize its effectiveness. Because Nol-Tec utilizes chemistry based CFD modeling we are able to ensure this criteria is met.
The system is also flexible to load and fuel changes. Pollutant removal is directly related to the amount of limestone being injected into the system. This is controlled by a loss-in-weight feeder which can be automatically adjusted in response to changing process conditions. A milling feature is included in the system to reduce particle size and maximize the available surface area for reaction.
