I. Core Technical Features
The system adopts a multi-chamber structure. Industrial combustible waste gas is preheated to above 800°C by ceramic regenerative media and thoroughly oxidized into CO₂ and water in the combustion chamber. The combustible removal rate remains stable above 99%, resulting in emissions far below national and local emission limits. Through precise airflow switching control and high-efficiency regenerative media, the heat recovery efficiency reaches up to 95%, minimizing heat loss.
II. Key Highlight: Three-Stage Waste Heat Recovery — Maximum Energy Utilization
The clean high-temperature flue gas discharged from the DS Combustion Purification system is no longer "waste gas" but a valuable heat resource. We have configured a cascaded waste heat recovery system:
• Stage 1: The high-temperature flue gas preheats the low-temperature waste gas entering the DS Combustion Purification system through a gas-to-gas heat exchanger, raising the initial temperature of the waste gas and directly reducing supplemental fuel consumption.
• Stage 2: The remaining high-temperature flue gas enters a waste heat boiler or thermal oil heater to produce saturated steam or high-temperature thermal oil, which is reused in production processes, workshop heating, driving absorption refrigeration units, or power generation units.
• Stage 3: The heat from the low-temperature section is further recovered through heat-pipe exchangers for domestic hot water preheating or material drying, achieving full energy coverage.
III. Economic Advantages for Low-Concentration Conditions
Even at a waste gas concentration as low as 0.5 g/m³, the system can generate considerable steam benefits through heat recovery output, substantially offsetting operating power and fuel costs. When the waste gas concentration reaches 1.2 g/m³, the DS Combustion Purification system enters a "self-sustaining" state without additional natural gas supply, truly achieving treatment with waste to enable resource reuse.
IV. Environmental Benefits
• Removal efficiency of combustibles such as CO and VOCs ≥99%, readily meeting environmental acceptance requirements;
• Annual reduction of hundreds of tons of CO or CO₂, accumulating carbon assets for the enterprise;
• No secondary pollution; the service life of the regenerative media reaches 8–10 years.
V. Applicable Industries
