Precise Temperature Control DTO Direct Fired Thermal Oxidizer Easy To Operate

Direct-fired thermal oxidizers utilize direct combustion heating with flexible fuel options including natural gas and fuel oil. These systems deliver high thermal efficiency, rapid heating capabilities, and precise temperature control for diverse industrial and civil applications. The compact design minimizes footprint requirements while automated operation ensures ease of use.

This waste gas incinerator serves as a critical environmental protection facility for 300,000 t/y propylene oxide production, processing 9,418-13,316 kg/h of industrial exhaust gases. Pressurized waste gas undergoes high-temperature oxidation at 900-1,100°C with sufficient residence time for complete combustion.

The system incorporates selective non-catalytic reduction (SNCR) technology with ammonia injection for NOx control. Heat recovery via waste heat boiler generates 9-12 t/h of saturated steam at 2.5 MPaG. The complete unit occupies approximately 40m × 25m.

Direct Thermal Oxidizers (DTO) heat the combustion chamber to set temperatures using fuel, then introduce VOCs which decompose into CO₂ and water at high temperatures. External equipment such as heat exchangers and boilers recover thermal energy from purified flue gas for energy savings.

Ruiding provides customized solutions based on airflow, composition, concentration, and removal efficiency requirements. High-concentration waste streams can maintain furnace temperature through self-sustaining combustion at moderate Lower Explosive Limits.

• High-temperature oxidation incineration achieves superior organic compound removal rates
