Urea-Based SCR System
Urea-Based HANLAN SCR System
Based on Nationwide's proven HANLAN™ SCR system technology, the urea-based HANLAN SCR system has been economically designed to provide reliable NOx performance for firetube and watertube boilers using a safe 32.5% urea solution. Utilizing direct injection of urea, this safe, low NOx SCR solution provides greater than 90% NOx reduction and eliminates the need for boiler operators to store or handle ammonia, while ensuring reliable operation of your boiler system.
Description
The urea flow control skid consists of a control panel with PLC touch screen HMI and air-atomizing injectors. A day tank can be supplied for storage, or standard urea totes can be utilized. The innovative design and features of this pre-packaged system assures minimum ammonia slip, maximum NOx reduction and easy installation and setup, while providing a safe alternative for ammonia based SCR systems.
