The Thermal Oxidizer system processes high-calorific waste liquids (atomized with 0.5MPaG steam) and low-calorific wastewater (atomized with 0.7MPAG compressed air). The combustion chamber ensures flue gas residence time ≥ 2 seconds at temperature ≥ 1100℃.
Waste heat boiler recovers thermal energy to generate byproduct superheated steam at 4.0MPaG/450℃, incorporating membrane walls, superheaters, economizers, and air preheater (Unit #1 only).
Flue gas treatment includes baghouse filter with pulse-jet cleaning, selective non-catalytic reduction (SNCR) denitrification with ammonia injection (850-1050℃ range), and induced draft fan for compliant emissions. System includes interfaces for future quench tower, dry sorbent injection, and selective catalytic reduction (SCR) units.
Operating Principle
The Direct Thermal Oxidizer (DTO) heats the combustion chamber to set temperature using fuel, then introduces VOCs which decompose into CO₂ and water at high temperatures, releasing significant heat. External equipment such as heat exchangers and boilers recover thermal energy from purified high-temperature flue gas for energy savings.
Ruiding provides tailored VOCs treatment solutions based on airflow, composition, concentration, and desired removal efficiency. When waste gas concentration is sufficiently high, the system can operate without fuel input, maintaining furnace temperature through self-sustaining combustion at moderate Lower Explosive Limits.
Key Advantages
- High-Efficiency Combustion: Optimal energy utilization through high-temperature oxidation combined with steam recovery via waste heat boiler
- Low-Emission Control: Baghouse filtration ensures dust compliance, SNCR denitrification reduces NOx emissions, precise temperature regulation maintains optimal reaction conditions
- Modular Design: Handles both high- and low-calorific waste liquids/gases in single system with future-ready interfaces for environmental upgrades
- Stable Operation: Guaranteed combustion parameters (residence time and temperature), robust equipment selection ensures long-term reliability
