Fume Incineration Systems

HiTemp offers both thermal and catalytic type fume incineration systems as well as one of the most efficient dual fuel electric and gas catalytic oxidizers on the market with applications for SVE, VOC, and CO emissions. We have developed technology in thermal and catalytic fume systems utilizing a two-pass design with preheat exchangers for VOC disposal. Destruction efficiency of our catalyst systems can be as high as 95 to 99% or more, with some of the lowest operating costs in the industry.

Fume Incineration System & Catalyst Module
SVE applications will typically have high VOC levels during the first few months of operation. In these applications we recommend our thermal oxidizer, Model HTT-FM-G with the optional catalyst module. The thermal systems can operate safely with VOC levels as high as 50% with operating temperatures up to 2,000oF.

In a few months, when the VOC levels drop, the catalyst module is bolted to the mounting flange and the temperature set-point is reduced to 550oF. The module is mounted to a flange located under the stack transition section. This system will dramatically reduce fuel usage. The AT module can be purchased as part of the original order, or added later as required.

HiTemp System Types

Systems can be designed for two basic types of waste gas streams. In the first and most common type, the application has a waste gas stream that is mostly ambient air containing a small quantity of VOCs. For these applications, the size selected is based on the flow rate in SCFM.

The second type is more complicated. In these applications, the gas stream contains little or no oxygen and high concentrations of VOCs. The system design must account for the amount of combustion air necessary to burn all the hydrocarbons in the stream while adding sufficient additional combustion air so the final exhaust gas contains a minimum of 8 to 10 percent oxygen.

Exhaust gas from a chemical process that contains almost 100 percent VOC can sometimes be injected directly through the burner nozzle. This type of system is started with natural gas bringing the Oxidizer up to temperature. Once temperature is reached, the waste stream is slowly added to the natural gas passing through the burner. As this occurs, the temperature rises so the natural gas is throttled back and the system then uses the waste gas displacing the natural gas.

Should the temperature in the chamber rise above set-point and the burner output throttles back to low fire, the second temperature controller opens the damper on a secondary air blower. During this condition, the secondary air is used to maintain temperature.

In some applications, the waste stream is diluted with secondary air before injection into the firing chamber. The same auxiliary temperature controller can be used to operate a bleed air T-valve controlling the amount of dilution air necessary during operation. For these special applications, we select a medium velocity, premix-type burner with an integral high-pressure combustion air blower sized for waste gas volume plus the required combustion air.

Also furnished with our standard units, is a natural gas valve train that includes solenoid shutoff valves, flamerod detection and gas butterfly valve with modulating control motor keeping the system in compliance with FM requirements.

Components may be furnished pre-piped and wired or supplied loose for installation by the customer prior to system installation.

HiTemp System Options

System options can include preheat exchangers, induced draft or secondary combustion blower, modulating dilution air "T"s, stack extensions and catalyst modules.

Our Catalytic Oxidizers function exactly the same as a Thermal Oxidizer. The major difference is the operating temperature necessary for destruction of the VOCs. The Lo-Temp Catalyst can operate effectively at temperatures as low as 400oF in some applications. The fuel savings at these lower temperatures can be significant in reducing operating costs.

Note: Catalysts cannot be used in applications where chemical poisons or particulates are present such as sulphur oxides (SOX) and silicone compounds.

With our 5 year warrantee, they will have no worries about dependability. We offer 100 to 50,000 scfm systems with destruction efficiencies of up to 99%+. Our proprietary low-temp catalyst is able to operate at 400 - 500 f. At this temperature, the operating costs are lower than RTO systems. And with our much lower initial costs, and faster delivery, we offer a much more attractive solution to your environmental problems. If you have a voc problem, we can help you solve it in the most economical way possible.
