HTB-DL burners are industrial-grade direct-fired ultra low NOx burners for operation in high temperature, high energy output environments. The HTB-DL are designed for maximum durability, minimum maintenance and flexibility in applying to existing furnace conditions. Control and operation characteristics are seamless on user side and the difference comes in lower emission profile, better combustion process quality and higher final product quality.
The burners share a simple box shape design, built-in burner throat and are capable of both cold start and high temperature operation. Due to lack of internal heat reclaim hardware preheated combustion air needs to be supplied from an external source – typically a central recuperator widely used with industrial furnaces.
Compared to HRS-DL burners, HTB-DL do not incorporate internal regenerators and so are smaller and lighter. The working principle is simple and similar to some of the other conventional high temperature burners – air is fed through burner throat into combustion chamber, fuel is injected via separate nozzles directly into combustion chamber.
