Flares
Safety flares are an indispensable element of many industrial plants. DWS is experienced in delivering flares to various industries, chemical, petrochemical, food & beverage in which anaerobic digestion is used to treat organic wastes and wastewater with the generation of biogas as a by-product. Besides serving as anti-explosion protection, flaring off excess gases and biogas reduces the load of greenhouse gases released to the atmosphere. We offer different flare variations depending on customer requirements and local conditions. You can count on a custom design, including use of equipment complying with the ATEX directive. When you choose DWS as your flare supplier, you can count on the commissioning and start-up of your flare by top industry specialists.

Elevated Flare
As one of the most used elevated flares around the world, our flare owes its popularity to its robustness, reliability, and durability. Just like our other flares, the elevated flare is designed to work consistently at ambient temperatures varying from -15 °C to +45 °C. No weather conditions nor dirt and water can prevent the system from sparking. In addition to our standard self-supporting free standing flare stack, flame arrester, ...

Shielded Flare
Shielded flares cover the majority of the flame behind a heat resistant shield. The flare construction makes it possible to safely burn the gases at a lower height than the elevated flares. In addition to basic components such as self-supporting free standing flare with the combustion chamber, instrumentation, and control panel, our shielded flare is equipped with: High retention burner; Ignition system with the weatherproof electrode; Flame detector; ...

Ground Flare
Temperature controlled ground flares allow for operation between 800 and 950° C (max 1100 °C) guaranteeing maximum methane oxidation. Besides keeping the flaring temperature within the required range, applied insulation is also an excellent noise muffler. In addition to basic components such as self-supporting flare stack, instrumentation, and control panel, according to our standards, every hot ground flare is equipped with: Temperature measuring ...

Biogas Dryer
Biogas leaving the anaerobic digesters or biogas desulfurization units can be oversaturated with water vapor, which can reach up to 25% of the biogas volume. While passing the pipes and other equipment, the temperature of the biogas decreases, causing the change of physical state of the vapor to liquid. The presence of hydrogen sulfide, nitrogen and carbon dioxide in the condensed water results in the formation of corrosive acids which destructive nature ...

Wet Biogas Scrubber
The wet biogas scrubber from DWS is an ideal solution for the treatment of biogas with hydrogen sulfide concertations between 1 to 5%. Biogas is blown through a column packed with porous material, with a high contact surface between biogas and washing liquid for an enhanced H2S ...

Biological Biogas Scrubber
To effectively condition high biogas volumes of biogas low in hydrogen sulfide (H2S < 1%) DWS advises the application of our highly-effective biological scrubber. This biotrickling filter utilizes chemolithotrophic bacteria to oxidize the hydrogen sulfide into sulfur or sulfate at a low capital cost and without large energy inputs, as it can be in case of membrane separation or chemical biogas scrubbers. For the continuous operation, the biofilter ...

Multi-Fuel Burner Systems
To successfully use biogas as a fuel, our engineers can design and implement modification of the burners at your plant. Whether those are indirect water heaters, steam boilers, turbines – you can start to operate them in multi-fuel mode thanks to DWS’ custom solution. Duel-fuel or multi-fuel burners include the possibility of operation with two or more gases or oil and gases streams. After implemented changes, the system can operate either on ...
