Automatic gas flare NOXmatic

horaky 1

Our core business is the most up-to-date quality gas flare technology for a safe, efficient and environmentally friendly combustion of gases from landfill, bio and sewage gas systems.

Our fully automatic flare NOXmatic with its extensive range of accessories can be suited for every low and medium temperature combustion application. With various burner systems we can cover the complete spectrum of power requirements in single or multi-stage operation.

The NOXmatic flare is manufactured entirely from stainless steel and equipped with high quality components (i.e., ATEX certified flame arresters, DVGW certified automatic and manual valves...).

All control and monitoring functions are achieved with an individual programmable controller, which also governs the signal transfer with the main controller.

NOXmatic flares can be delivered worldwide with a capacity from 100kW to 20MW.


High temperature flare NOXtreme

High temperature combustion in gas flares is required when specific combustion parameters must be adhered to (TA Luft, governmental or local regulations) for reasons pertaining to the environment. One such parameter includes, but is not limited to, the emission of carbon dioxide (CO2) or nitrogen oxide (NOX).

With special burner technology and a suitable combustion chamber suitable for temperatures > 1000°C, the ennox high temperature flare provides for and controls the correct combustion temperature. Our flares are designed to satisfy even the most demanding applications. 
At the heart of the NOXtreme flare control is the fully automatic control from the NOXmatic unit, which, if required can be extended to meet the actual project demands.

The temperature control of the combustion process can be achieved either with a manual or automatic combustion air regulator.


Landfill gas cleaning and safe incineration

horaky 3

Every year, millions of tons of household garbage and other refuse are deposited in landfills around the world. Bio-chemical decomposition processes of organic bonds in these landfills produce up to 150 - 250 m³ of landfill gases per tonne of household garbage. 

Due to a methane content of up to 60%, landfill gas ranks number six on the list of climate-disrupting methane producers worldwide, but it is also an important source of energy with enormous potential if used sensibly.

Up to a content level of approximately 40% methane, landfill gas may still be recovered usefully in modern block heating plants. The important factor in this case is an effective and project-specific pre-cleaning process for the gas.

We can help by providing you various gas cleaning systems, gas drying systems, and activated carbon filters, and pressure increasing stations. The components may be used as individual models or delivered as a complete system that is built into a container.

Landfill gas featuring less than 40% methane content is no longer sensible for use as energy and may be incinerated in an environmentally safe manner in special enclosed ennox high-temperature gas flare systems. Toxic and ozone-harming components of landfill gas are destroyed thermally in the process.

For temporary uses or when technologically possible, open landfill gas flares may also be used. We will provide you the right gas flare for any application including the correct incineration process!

ennox is one of the world's leading providers in the area of preparation and recovery of landfill gas, and its excellent know-how, flexible and enthusiastic engineering and production team is always ready for new challenges.


Special flares

  • NOXmatic BM (bio-methane/natural gas)
  • NOXmatic / NOXtreme CDM (CO2 trading scheme projects)
  • manual flare ECO
  • NOXmatic NANO (mini flare, small gas flow, possibility to fix on container)
  • mobile flare
  • customized flares (wood gas, pyrolysis gases etc.)

The Ennox flare portfolio completes the following variations like for example NOXmatic BM used particularly for the bio-methane combustion, which is the biogas converted to natural gas quality,  NOXmatic / NOXtreme CDM used for JI and CDM projects which are involved into the worldwide CO2 permits trade scheme (scope of supply can be extended with a blower and gas purifying station and a flare with necessary equipment for monitoring and recording the combustion process),  manual flare ECO and NOXmatic NANO (automatic mini flare for low gas flows with the possibility to fix the flare on the container wall) plus finally the mobile flare. Ennox is able to design and deliver special customized flares, for example wood gas or synthetic pyrolysis gases etc. (gases containing high explosive hydrogen etc.) – if you are not sure if we can match your demand for the suitable gas flare, please don´t hesitate to contact us with your demand and we will suggest the optimal technical configuration in terms of your task.
