Crawford manufactures a diverse range of modular, multiple chambered, controlled air, solid waste thermal oxidizers (incinerators), engineered for the unique demands of a wide array applications. Designed specifically to accommodate environmentally responsible, safe and effective solutions, our systems incorporate advanced combustion control technologies providing controlled primary chamber combustion achieving typically over 95-98% volume reduction to a safe, sterile ash. Advanced, controlled air secondary combustion chambers provide efficient, turbulent thermal oxidation of combustion gases, with over 2 second retention, standard, for environmentally safe stack exhaust to atmosphere.
With capacities ranging from 15–2000 lbs/br (7-900 kg/hr). we offer system to address a wide array of effective solutions for solid & liquid waste disposal as well as pathological/incineration systems, with custom designs available to meet unique application demands.
Incineration Systems can be configured for manual charging, batch cycle operation or with continuous automated with hydraulic ram loaders, automatic stoking and automatic ash removal systems to meet a wide range of operational needs.
Wide Applications: Medical waste, Hazardous waste, Municipal waste, Industrial waste, both solid and liquid waste incineration…
