For half a century SPG Steiner GmbH has been designing, engineering and manufacturing under its business unit PREMATECHNIK the next-generation of combustion equipment, flare systems, industrial burners and advanced environmental systems. Combining our extensive technical combustion experience and own high quality manufacturing yard made in Germany our clients can be ensured about the longevity of our products, optimizing emissions, destroy pollutants and ensuring a safe and best possible performance operation of their facility. Our equipment plays safety and emission-critical roles in the oil and gas, petrochemical, chemical pharma and energy industries around the globe.

We design and manufacture every flare to deliver superior safety performance without compromise for smokeless performance.

Flare system types

Throughout our company history we have built of almost every type of flare structure. These range from freestanding derricks, guyed risers, self-supported, and multi riser-structures. Derrick structures that are capable of being demounted, whereby flare stacks can be spared, such as one duty stack and one stand by the stack.

Flares of any design and height are equipped with environmentally friendly gas oxidation aids as required. The aids are, as a classic variant, steam, blower air or supporting gas. In addition to sonic flares, special burners are used to extract the necessary combustion air.

Steam Assisted Flares

Steam-assisted flares are used in applications where heavier waste gases need to be disposed and high-pressure steam is readily available on site. Our proprietary flare designs offer exceptional smokeless performance, lower radiation levels, and less noise than typical air-assisted flares.

Air Assisted flares

Air-assisted flares use blowers to inject combustion air directly into the waste gas stream as it exits the tip, resulting in smokeless burning and long flare tip life. This solution ensures an efficient combustion of heavier waste gases at sites where steam or even water are not available or economical.

Gas-Assisted Flares

Gas-assisted flares are used to make poorly oxidizing gases combustible or to inject additional air via injections. Multi Point flares are used to increase the surface area of the air required for oxidation and thus burn soot-free.

For the protection of the environment to prevent or reduce  bad emissions, Prematechnik developed the PremaNOX® burner to minimize the formation of NOx and CO emission, tested and approved by an independent German institute. PremaNOX® burners are mainly used as gas staged type, however, they can also be used as air staged type. 

The burners are dimensioned individually according to the specification of our customers and are suitable for capacities of 0.5 – 5 MW. Main application areas are methanol plants, H2 plant and CO plant. PremaNOX® are down-firing burners, fuel staged and operated with forced air. The burners are also suitable for the operation with varying gas mixtures.
