Thermal Oxidizers 

Thermal Oxidizers to meet your requirements
Let our experienced thermal oxidizer engineering group focus on meeting your individual requirements. Our broad base of incinerator designs and wealth of experience allow us to evaluate your environmental problems and provide custom designed solutions for your specific situation. Callidus incineration systems are in service in a variety of gas and liquid waste applications including halogenated, chlorinated, fume, tail gas and nitrogen bearing wastes. Each system is designed and built to meet the highest quality standards and to meet or exceed the latest environmental regulations including NOx standards.
DeNOxidizer System
Thermal Oxidation of nitrogen-bearing wastes require a specialized combustion approach. Single-stage combustion of these wastes can produce NOx emissions in excess of those allowed by most regulatory agencies. To maintain NOx emissions within acceptable limits, Callidus uses a three-stage process to destroy wastes.
Fume Thermal Oxidizers
Fumes can be air, inert or organic based. An air based fume stream is generally destroyed at a temperature of 1400 to 1600° F. Destruction efficiency can range from 90 to 99 percent. Because they contain very little organics, a preheat exchanger downstream of the oxidizers is used to reduce fuel consumption by preheating the incoming fume stream.
Halogenated Waste Systems
Callidus’ Halogenated Waste Incineration Systems are capable of destruction efficiencies exceeding 99.99 percent. Depending on the destruction efficiency required, operating temperatures of 1500 to 2200° F can be used with residence times of 1.0 to 2.0 seconds. Downfired System
Liquid Waste
SRU Combustion Equipment
Tail gas from Sulfur Recovery Units for acid gas contains a variety of sulfur compounds, which must be destroyed by combustion before the gases are vented to the atmosphere. The units can be natural draft or forced draft operated. Oxidizing temperatures can vary from 1200 to 1800° F with residence times of 0.6 to 1.0 seconds.
System for Organic Wastes
Aqueous or organic waste streams containing inorganic or organic salts require that the Thermal Oxidizer be down-fired to prevent the accumulation of molten salts in the oxidizer furnace.
