Thermal oxidizer, sometimes called thermal oxidiser and thermal incinerator, is environmentally friendly equipment for the treatment of volatile organic compounds (VOCs) produced during industrial production. Before the waste liquid gas produced in various industrial processes is discharged into the atmosphere, the thermal oxidizer is used to effectively destroy the waste liquid gas, so that the emission of waste liquid gas pollutants can be greatly reduced. In order to destroy the harmful components (VOCs and hazardous air pollutants HAPs) in the waste liquid waste gas pollutants, the thermal oxidizer adopts the “thermal oxidation” principle. “Thermal oxidation” is a combustion process in which pollutants and oxygen undergo oxidation reactions under extreme high-temperature conditions. The products of this chemical reaction are harmless substances such as carbon dioxide, water vapor, and heat, and can be safely discharged into the atmosphere. This is the thermal oxidizer working principle.
What VOC means?
The World Health Organization (WHO) defines VOC as an organic compound with a melting point lower than room temperature and a boiling point between 50 and 260°C. These are volatile organic compounds that can cause harm.
There are many types of VOCs, such as aromatic hydrocarbons (such as benzene, toluene, xylene), aliphatic hydrocarbons (such as ethylene, butane, hexane, octane, etc.), halogenated hydrocarbons (such as carbon tetrachloride, freon), alcohol ( Such as methanol, ethanol), aldehydes (such as formaldehyde, acetaldehyde), ketones (such as acetone), carboxylic acids, esters, ethers, terpene compounds and tetrahydrofuran, etc. belong to the category of VOCs.
VOCs can be widely used as liquid fuel, solvent or raw material or medium for chemical reaction, the emission volume is large. Besides industrial resource (including no plan leakage),the storage and transport of organics, vehicle tail gas, waste water treatment facilities will create certain amount of VOCs.
Ruichang VOC Thermal Oxidizer
The VOC thermal oxidizer launched by Ruichang adopts a direct-fired design, which is suitable for the purification treatment of harmful exhaust gas in petrochemical, painting, coating, pharmaceuticals, and other industries, and supports the treatment of one or more mixed exhaust gas. The structure of direct fired thermal oxidizer is divided into horizontal and vertical. There are fixed and mobile installation methods.
VOC Thermal Oxidizer Application Scope
Ruichang Direct Fired Thermal Oxidizer
In order to deal with different concentrations of waste gas, Ruichang has developed two kinds of direct fired thermal oxidizer processes, namely, waste gas combustion process flow(TO) and adsorption concentration + combustion process flow.
VOC thermal oxidizer system is using a patented arc plate heat exchanger to exchange heat with flue gas and VOCs, after heat exchange, VOCs and combustion air will enter the combustion chamber for high-temperature combustion and VOCs will convert into CO2 and H2O, after cooling, flue gas will enter stack and emission to the air, and the flue gas emission meets relevant emission standards.

After adsorption, the volume of hot air with flue gas to concentrate to below 10%, the fuel quantity for combustion is low, flue gas volume is sharply decreased, and the equipment size needed is small with low weight.
All in one structure for combustion and heat exchange equipment, BMS skid at upstream, low working load onsite with highly auto-control.
Arc-shaped plate structure for heat exchange equipment, plate type structure for air preheater, high heat exchange efficiency with low land occupation.
The all-in-one heater can be a vertical layout, low land occupation, and reduce the stack height.
The all in one heater can be fixed or movable type.
