GeneralFlame has developed a rotary kiln SNCR denitrification system for rotary kiln flue gas. The core component, the rotary kiln SNCR denitrification lance (spray gun), atomizes urea solution or ammonia water into fine mist particles. These particles then mix and react chemically with the flue gas, removing nitrogen oxides (NOx) and achieving the goal of reducing NOx emissions. The rotary kiln SNCR system primarily consists of a urea solution preparation and storage tank area, a buffer support device, an internal kiln rotary support device, a spraying system, and related control systems.

The SNCR flue gas denitrification process is accomplished through four basic steps: receiving and storing the reducing agent; injecting the diluted reducing agent at an appropriate location; metering the output of the reducing agent, mixing and diluting it with water; and mixing the reducing agent with the flue gas for the denitrification reaction.

The rotary kiln SNCR process system mainly includes the reducing agent storage system, circulation and conveying module, dilution and metering module, distribution module, rotation module, reducing agent injection system, and associated instrumentation and control systems.
