Regenerative IncineratorRTO Is A Mature And Highly Effective Organic Waste Gas Treatment Equipment, With A Waste Gas Treatment Rate Of Up To 90% And A Wide Range Of Applications. However, Under The Current Dual Carbon Background, The Operational Energy Consumption Of RTO And Its Contribution To Carbon Emissions Have Gradually Attracted Attention. At Present, RTO Equipment Has Basically Achieved PLC Fully Automated Control, So Its Energy Saving Is Mainly Reflected In Reasonable Technical Design And The Effective Utilization Of Combustion Exhaust Heat Energy. So What Are The Main Factors That Affect The Energy Consumption Of RTO Operation?
1. Gas Supply Design
To Improve The Processing Efficiency Of RTO, It Is Necessary To Provide A Reasonable Gas Supply To The Combustion Chamber Of The RTO Furnace During Combustion. When The Gas Supply Is Insufficient, It Not Only Leads To Incomplete Combustion, But Also Produces A Large Amount Of Carbon Monoxide; When The Amount Of Oxygen Is Excessive, It Will Cause More Heat Energy To Be Lost Along With The Hot Air Flow, Resulting In Heat Loss.
Based On The Experience Of Using A Combustion Furnace, Controlling The Concentration Of Combustible Organic Compounds In The Exhaust Gas To 25% Of The Lower Explosive Limit (LEL) And Matching A Reasonable Amount Of Air Can Not Only Save Fuel, But Also Enable The Full Combustion Of Combustible Substances, Purify Exhaust Gas, And Reduce Pollutant Emissions.
2. Combustion Temperature Design
The Combustion Chamber Temperature Is One Of The Key Factors Affecting The Efficiency Of RTO Treatment. Research Has Shown That At Temperatures Above 760 ℃, Most Organic Gas Molecules Can Be Completely Destroyed, Resulting In More Complete Reactions And Oxidation To Produce Water And Carbon Dioxide.
Reasonable Selection Of Combustion Temperature Is Important For RTO Design, And Appropriately Increasing The Furnace Temperature Can Make The Oxygen Combustion Reaction More Complete And Energy-saving. However, Blindly Increasing The Furnace Temperature Will Increase Heat Loss, Shorten The Service Life Of The RTO Furnace, And Thus Increase Costs. At The Same Time, Higher Furnace Temperatures Also Consume More Fuel, Resulting In A Decrease In Exhaust Gas Purification Efficiency And Affecting The Emission Standards Of Exhaust Gas.
3. Furnace Space Design
The Furnace Space Of Technology Can Provide A Reasonable Residence Time For Organic Waste Gas In The Furnace, Thereby Promoting The Complete Oxidation And Combustion Of Organic Matter. The Reasonable Residence Time Depends On Factors Such As The Cross-sectional Area, Length, And Gas Flow Velocity Of The Furnace. According To Empirical Values, The Residence Of Exhaust Gas In The Furnace For 1.0-1.3 Seconds Usually Meets The Emission Standards For Exhaust Gas.
4. Quality Of Thermal Storage Bricks
Thermal Storage Bricks Can Absorb The Heat Released By VOCs And Gas, And Be Used For Circulating Heating Of Newly Introduced Organic Waste Gas. The Use Of High Specific Heat Fusion And High Thermal Conductivity Thermal Storage Bricks Can Improve The Utilization Rate Of Heat.
5. Structure Of RTO Thermal Storage Incinerator
RTOs Are Mainly Divided Into Two Bed, Three Bed, Multi Bed, And Rotary Types. Typically, Rotary RTOs Have A Compact Structure And A Large Number Of Heat Storage Chambers, Resulting In A Higher Utilization Rate Of Heat By The Overall Heat Storage Bricks.
6. Leakage Rate Of High-temperature Valve
The High-temperature Valve Is An Anran Valve Directly Connected To The Furnace And Chimney. Due To Its Operation In A High-temperature Environment Of About 850 ℃, It Has A Certain Leakage Rate. The Leakage Of High-temperature Valves Can Cause Heat Loss, And The Lower The Leakage Rate, The Better.
Therefore, The Energy Efficiency Of RTO Can Be Determined By The Exhaust Temperature At The Chimney Outlet. The Exhaust Temperature At The Chimney Outlet Generally Does Not Exceed 100 ℃, Which Can Directly Determine The Thermal Storage Capacity Of The RTO And The Sealing Ability Of The High-temperature Valve.
