What Role Does A Thermal Oxidizer Burner Play In Helping Reduce Pollution?

Higher disease risks and unpredictable temperature changes are two of the most well-known harmful effects of air pollution.

VOCs (volatile organic compounds) are a class of chemical gases produced by a range of activities as well as some solid objects or liquids. VOCs are produced when fuels such as gasoline, wood, coal, and natural gas are burned.

VOCs must be destroyed before they reach the air, to reduce their negative effects and air pollution. Before harmful VOCs in emissions reach the external air, thermal oxidizers and ground flares successfully cleanse them. Let’s look some more into the working of a thermal oxidizer burner.

Some VOCs are hazardous and can cause cancer. Other VOCs can react with gases to produce dangerous pollutants in the air. When VOCs combine with nitrogen oxides, which are commonly generated by car exhaust and the burning of coal, diesel fuel, oil, and natural gas, they can cause harmful smog.

Thermal oxidizers are widely used to remove VOCs in industrial air streams. A combustion chamber and a discharge stack are used in a thermal oxidizer burner to expose untreated air streams to oxygen and high temperatures. VOCs are broken down into carbon dioxide, water vapor, and other harmless heat-based compounds after being exposed to heat and oxygen for a set amount of time (residence time).

Manufacturers can release the gas stream into the atmosphere as a non-volatile substance after heating the VOC-laden air in a combustion chamber.

Thermal Oxidizer Vs. Flare: What Are Flares?

 

Ground Flares

Ground flares are used by refineries and petrochemical plants to burn excess hydrocarbon gases that cannot be collected or repurposed. Flare systems are used to burn excess hydrocarbon gases in a safe and environmentally friendly way.

Enclosed or open ground flares are available. While the enclosed and open ground flares have distinct construction, the procedure is fundamentally the same. Both enclosed and open ground flares successfully remove VOCs, and the procedures are less obtrusive than the massive stacks of a thermal oxidizer burner.

Excess gases are combined with steam and/or air in the ground flare process, which is subsequently burned off to produce water vapor and carbon dioxide. The procedure is similar to that of burning liquefied petroleum gases (LPG), which is commonly used as cooking fuel.

Ground Flares, Both Open And Closed

Open ground flares can withstand high gas flow rates and burn larger amounts of gas at once. The units emit almost no smoke and have a high gaseous conversion rate. To operate, open ground flares require vast land clearances, and the units must be kept at a safe distance.

Without the use of a stack, an enclosed ground flare system turns potentially poisonous or flammable gases into less damaging vapor. Vertical combustion chambers with natural air draught are featured in the units. Radiation, the interior blaze, and noise are all shielded by a refractory shell that surrounds the cremation process.

Low and medium gas flow rates can be managed with enclosed ground flares. They don’t take up as much room as open ground flares. These devices can be used to burn gas, liquid, or a combination of both in an emergency.

Thermal Oxidizer Vs. Flare: The Final Verdict

Thermal oxidizers and ground flares are both safe and efficient ways to eliminate VOCs from the air. These procedures aid in the prevention of harmful compounds entering the atmosphere and the reduction of air pollution.

What Is An Electric Thermal Oxidizer And What Are Its Benefits?

 

If lower volumes of waste gas streams need to be treated, electric-heated thermal oxidizers can be used. If there are scrubbers and filters with limited capacity, it may be more cost-effective to employ electric heating.

Instead of using a gas thermal oxidizer burner to heat the filthy air to the catalyst operating temperature, an electric TO employs electric heaters. The TO’s flameless option makes it a suitable emissions control system for facilities without convenient access to natural gas or those concerned about gas-burning systems’ potential risks. Additionally, the TO is an excellent option for businesses looking for a more environmentally friendly air treatment system.

Reduced Harmful Emissions – Because there are no combustion products of natural gas and no creation of NOx, this system reduces harmful emissions and their contribution to pollution.

Lower Installation and Operating Costs – When compared to other air pollution control devices, an electric thermal oxidizer is simple to install. Because there is no requirement for natural gas or the installation of appropriate gas lines, this system has cheaper installation costs. Facilities that don’t have a burner don’t have to worry about extensive system maintenance or the NFPA-mandated annual burner inspections.

Flexible Unit Design – TOs are a good choice for facilities with a small footprint or that want to put their air pollution control system in a specified position. The enclosed TO’s design makes it lighter and more compact than typical oxidizers; it takes up less room and may be mounted on a skid or the roof. Compared to traditional thermal oxidizers, this unit is smaller, requires less maintenance due to fewer moving parts, and is more easily accessed.
