DWS BVBA products

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 biogas only or if in case of dual-fuel mode – biogas and other gas simultaneously. The heat or steam demand dictates the regulation of the biogas and supplementary fuels flow as needed for uninterrupted operation. All the necessary instrumentation, valves, and filters are always chosen based on customer needs and local conditions.

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, instrumentation, and control panel, every elevated flare is equipped with DWS’s: high retention flare tip; high energy ignition system with high-temperature weatherproof electrode for direct ignition of the main burner; flame detector. All the valves and additional equipment can be provided in accordance with the ATEX directive.

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; Flame arrestor; Waterlock for automatic condensate removal. All the valves and additional equipment can be provided in accordance with the ATEX directive.

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 transmitters; Temperature controller build in the control panel; The 100 mm thick mounted ceramic stack bound; Two air dampers integrated into the body of the stack to control the burning temperature; High retention low NOx burner; Ignition system with the weatherproof electrode; Pilot burner; Fail-save UV flame detector; Flame arrestor. All the valves and additional equipment can be provided in accordance with the ATEX directive.

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 dissolution.
