firing The process of applying fire or heat, as in the hardening or glazing of ceramics; flaring 1. Flares use open flames during normal and/or emergency operations to combust hazardous gaseous. The system has no special features to control temperature or time of combustion; however, supplemental fuel may be required to sustain the combustion. Historically, flares have been used to dispose of waste gases in the oil and gas industry and at wastewater treatment plants having anaerobic digestors. Regulation for thermal destruction of hazardous wastes limit the practical use of flaring to combustion of relatively simple hydrocarbons, such as methane from digesters or landfill gas collection systems. 2. A control device that burns hazardous materials to prevent their release into the environment; may operate continuously or intermittently, usually on top a stack; incineration Controlled process by which solid, liquid, or gaseous combustible wastes are burned and changed into gases; residue produced contains little or no combustible material |
