High Temperature Fire Side Injection Quill

A Southeast, "wood to energy" facility was experiencing long and drawn out turn around time on their shut downs and general maintenance schedule due to the substantial build up on the outside heat exchange surfaces of the boiler tubes. The slag would have to be dynamited off which is costly and dangerous.
The chemical supplier developed a product, however feeding it into an 1800 degree chamber proved to be another issue.

High Temperature Fireside Injection Quill

We developed the High Temperature Fire Side Injection Quill which would allow the product to be fed, and we utilized air to cool the product and the quill at the same time. This kept the additive from flashing prior to being delivered into the fire box.

Inner Shell, Outer Shell Injection Points

The High Temperature Fire Side Injection Quill has an inner and outer shell for cooling and to facilitate a more dynamic delivery system.

Cooling Air Injection Point for the Outer Shell

The result was a dramatic reduction in down time and it eliminated the need for blasting the deposits off the tubes.
This improved safety and productivity for the facility.
All alloys used in the development of this high temperature quill were specifically selected for this application.
