Derrick type stacks are one type of support system for an elevated flare. The elevated flare tip is mounted on top of a riser supported by a steel trussed (derrick) structure. Derrick supported flares require three or four additional foundations for the derrick legs, but this is a relatively smaller plot space when compared to a guyed flare of the same height. Derrick flares eliminate process temperature design concerns. Additionally, a single common derrick structure can support multiple flare risers. 

MZ focuses on all kinds of industrial waste gas treatment, especially for the design, equipment fabrication and EPC contract service for flare gas discharge and recovery system. Provide flare gas discharge system essential safety and HSE assessment; Provide reasonable and economic assessment; Heat radiation, noise, stack diameter/height and pressure drop calculations via FLARESIM software; Combustion area temperature/pressure & burn out rate calculations and flare tip or molecular seal design via Fluent software; System balance, stress analysis and piping design via Caesar IIand flare. NET software; By using simulation and corresponding experiment to ensure the essential
