Thermal Oxidizer, Regenerative RTO, Catalytic RCO, DFO/Incinerator 2017-05-24T18:57:14+00:00

A.H. Lundberg’s thermal oxidizers are designed to handle gases of varying concentration and composition to meet or exceed all environmental requirements.

Operators of industrial processes that emit Volatile Organic Compounds (VOCs) have long known that thermal oxidizer is the best solution to employ in the destruction of these emissions. The challenge, however, is minimizing fuel and operating costs while destroying the VOCs.

AHL’s Regenerative Thermal Oxidizer (RTO) and Regenerative Catalytic Oxidizer (RCO) are a proven economical and energy-efficient family of technologies designed to meet this challenge.

In addition, AHL also offers Direct Fired Oxidizer (DFO), which has become the primary point for disposal of the waste gas streams for many clients in the pulp and paper industry. The oxidizer is designed to thermally oxidize the contaminants contained in the waste gases such as strong, dilute, and stripper off gas.

Regenerative Thermal Oxidizer and Regenerative Catalytic Oxidizer

AHL’s Regenerative Thermal Oxidizer incorporates high preheat efficiency with broad operational flexibility. It allows your industry to economically achieve compliance with strict local, provincial and federal emission regulations. While designed to safely operate at up to 1100 °C, typically the unit operates at 840 to 870 °C

AHL’s Regenerative Catalytic Oxidizer provides industries with a proven, low temperature solution for VOC emission control. Compared to an equivalent duty RTO, the RCO is smaller and less expensive in capital and operating cost since it operates at a low temperature of 450 °C.

RTO and RCO are ideal to address industrial processes such as:

  • Petroleum storage tank vapours

  • Bitumen storage tank ventilation

  • Truck and rail car loading vent capture

  • Ethanol storage tank ventilation

  • Paint curing ovens

  • Insulation manufacturing

The hallmark of AHL’s design is simplicity, which equals to ease of maintenance and high reliability. Each system is designed as a vertical “tank” internally divided into twin heat recovery chambers. Fast acting poppet valves are utilized to switch the direction of the gas stream in the heat recovery chambers.

Design Criteria:

  • 98 to 99% destruction efficiency

  • Up to 95% thermal efficiency

  • Heat exchange media designed to meet the requirements of each application

  • State-of-the-art controls custom designed for each application

  • Complete turnkey systems available

Direct Fired Oxidizer

AHL’s DFO (or incinerator) has been specifically developed over the years for the harsh environments of the Pulp and Paper industry. It is also appropriate for thermal oxidation of waste gases in other industries. The incinerator is designed to provide VOC destruction efficiencies exceeding 99.99%. AHL has more than 35 DFO systems operating worldwide.

These incinerators may be designed for continuous or intermittent (rapid start-up) operation, as appropriate. Enhancements to thermal oxidizers may include:

  • A fire tube waste heat boiler to generate low pressure steam

  • A tail gas scrubber to capture sulphur from the waste gas

Specialized Burner Nozzles:

When thermal oxidation of waste gases is possible by injection into an existing incinerator, kiln, or boiler, we offer custom designed burner nozzles to safely inject the waste gas and assure complete destruction. The burner nozzles may be designed for multiple feeds, separate support gas, combustion air or a combination.
