Enclosed Ground Flare

Enclosed Flares (VCUs) designed and manufactured by Combustion Research Associates offer smokeless flaring of various pollutants such as Hydrocarbon gases and vapors, Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs). With a concealed flare, these stacks pass stringent regulations against visible emissions, vapor radiation, noise pollution etc. With a refractory (Ceramic Fiber Insulation) lined combustor stack, our Enclosed flaring systems allow for operation in plants with proximity to crowded areas, processing equipment, environmentally sensitive area or where the potential of complaints exists from the surrounding community. With over 99% destructive efficiency, our thermal combustors work effectively in-turn reducing operating costs. Advantages such as burning at ground level and smokeless and invisible flame make them perfect for gases such as Natural Gas, LPG, Biogas, Landfill gas, Producer Gas, Petrochemical, Syn gas, CBM gas, vapors etc.
