EMB-SIK-NxT - Recuperative burners high speed ultra low NOx in SIC

The EMB-SIK-NxT are “nozzle mix” type; preheated air and fuel are mixed in the combustion head preventing dangerous flashbacks, the air flow together with the shape of the silicon carbide head produce a tense flame which allows a high penetration of heat inside the combustion chamber. The EMB-SIK-NxT burners are LOW NOx burners and apply staged combustion techniques to guarantee low NOx and CO emissions. The body is internally insulated to reduce risks for the operators.

Description

The EMB‑SIK‑NxT series is a family of high‑velocity, ultra low NOx gas burners designed for industrial furnaces requiring efficient heat transfer, low emissions and reliable operation with preheated combustion air. These “nozzle mix” burners mix fuel and air directly at the combustion head, eliminating flashback risk and generating a tight, penetrating flame thanks to the silicon carbide head. Their typical applications include ceramic and fibre‑coated furnaces, heat‑treatment furnaces, tunnel kilns, chariot furnaces, dryers and galvanizing lines.

The burners operate with combustion air preheated between 200°C and 500°C (up to 600°C in BH versions) and cover a power range from 100 to 700 kW. Their construction features a cast‑iron mixer and collector, silicon‑carbide flame tube, and AISI310 combustion head. The NxT technology ensures reduced NOx and CO emissions through multi‑stage combustion and strong exhaust‑gas recirculation, even during cold start‑ups when chamber temperature is low.

Ignition and flame detection occur through separate electrodes, both supplied with the burner. The EMB‑SIK‑NxT‑BH variant includes a refractory block holder, allowing operation in extremely high‑temperature environments (up to 1400°C) with excess air up to 400% and flame speeds up to 120 m/s. These are suitable for annealing, stretching, NOx‑galvanizing lines and other severe applications.
