Thermal Oxidizers
you can expect the best Solutions from the OXPERT.
Nacah Tech provides the process design, mechanical design, BMS / PLC (control system) design, material procurement and fabrication, installation supervision and commissioning of Thermal Oxidizer Systems with many available accessories such as LEL analyzer, flow meters, controls, waste heat recovery, preheaters, flame arrestor, id fan, and stack. Each system thermally decomposes the VOC’s in waste gas(es) (VOC laden “air”) from a production facility. The TO system is designed based on the information specified. Nacah Tech designs, manufactures, delivers & commissions TO system for use at a wide variety of industrial, process or other plants.
Comparison of types
Our systems are individually engineered to fit your specific process needs, space requirements, and budget.
direct fired thermal oxidizers
Custom designed direct fired thermal oxidizer units (DFTO) accommodate unique application considerations including externally mounted nozzle mix burner (shown) or an inline duct burner.
- Regulatory compliance with optimal capital cost
- Compatible with other energy-saving equipment such as waste heat boilers and heat exchangers to meet corporate / plant sustainability goals when needed.
- Effective solution for large or small VOC stream treatment (Nacah Tech provides custom system to solve customer issues of many types)
- Allows efficient heat capture from high VOC streams (improve OPEX for customer)
- Efficient for batch loaded processes as well as continuous.
- Customization allows customer to operate as desired
Recuperative Thermal Oxidizers
Recuperative thermal oxidizers best suit VOC laden air streams with sufficient loading that provides more heat than for sound RTO’s operation but insufficient normal loading for DFTO (direct fired thermal oxidizer). Recups reduce the operating costs to an optimum level while not overheating or overloading the system. VOC concentration high enough to cause overheating of RTO media but sufficiently low (within a range) to not overheat a gas to gas recup system steers design to recup.
A recup sample TO treated dynamometer exhaust coming from multiple engine test stands with varied loads. This style of operation matches many batch processes in applications for chemicals, petrochemicals, food, and many more. Sometimes a unit available for rent may get the customer through an immediate or temporary need.
RTO’s high efficiency used for
“clean” High flow rates, LOW VOC
CUSTOM DESIGNED THERMAL OXIDIZER
If one or more of the following parameters apply, a custom thermal oxidizer is likely the best solution.
- Flow changes
- N-bearing compounds
- High Destruction Rate Efficiency (DRE) required
- Fluctuating VOC or heat content of waste/off gas
- Plant requires post-combustion Air Pollution Control (APC)
- Particulate concern
- S or Halogen presence
- Fluctuating flow rates
- High, reduced, or low O2 in stream
Thermal Oxidizer for Asphalt SHINGLE PLANT Application
Custom sized unit to accommodate unique process requirements.
- Blowstill and tank fumes abated
- Railcar and truck loading treatment incorporated as needed
- Combine sources with process converters to minimize fuel consumption
- Waste heat recovery to heat flux , therminol or preheat combustion air to improve sustainability and reduce OPEX, or maintain tanks
- Provide steam if/when needed
- Help prevent unwanted or unforeseen shutdowns due to blowstill off gas condensate/tar build-up (improve uptime of plant)
- Improved availability through experience
- Personnel protection and improved efficiency or fuel savings by minimal heat loss
