Hauck NMG/NMC Nozzle Mix Gas/Oil Combination Burner

The Hauck NM nozzle mix burners are designed for applications requiring a general purpose, long life, low maintenance burner. Fires most gaseous fuels, No. 2 oil or gas/oil combination. Preheated air models to 800ºF (425ºC).

Operation
Combustion air and fuel are channelled into the burner nozzle separately, permitting wide turndown. Since the burner nozzle is sealed into the refractory tile, all combustion air is supplied through the burner. The NM series burners couple a uniform flame front with flame stability over the entire operating range.

NM burners are available for preheated air operation up to 800ºF (425ºC) for high-temperature furnace applications. Atomizing air is maintained at ambient conditions during preheated air operation.

NM burners can be controlled manually or automatically. Automatic control normally employs a Hauck Ratio Regulator for each control zone or burner to maintain the air-fuel ratio. An alternate system uses control valves in each of the fuel and air lines,
linking the valves to a single motor controller.

Use of the burner in recuperative systems results in an economical approach to energy savings.

Construction
With no moving parts, the burner is virtually maintenance free. Parts subject to heat are constructed of either heat-resistant cast iron or stainless steel. The tile is manufactured, dried and cured by Hauck.
