An incinerator is a structure designed to burn waste, processing the by-products (e.g. bottom and fly ash) so that their impact on the environment and persons is strictly controlled. Many incinerators now recover waste in the form of electricity or thermal energy. Thermal incinerators (also known as recuperative incinerators, direct flame incinerators, thermal oxidizers) and catalytic incinerators (also known as catalytic oxidizers or catalytic reactors) essentially oxidize and deplete noxious fumes.
Thermal Incinerators
Thermal incinerators diminish the waste-gas volatile organic compounds (VOCs) from such operations as industrial dryers, kilns and ovens. The fastest and safest method to eliminate VOC's is oxidation. In this process, the polluted air is heated to the point where the majority of the organic materials oxidize into water and carbon dioxide.
Thermal oxidizers may be either recuperative or regenerative. In cases where the excess energy can be recovered and reused in the production process, recuperative oxidation is unbeatable. This process is known to be robust, safe, and universally applicable. Due to its minimal use of additional energy, and cases where recovered energy cannot be reused, the trend clearly goes towards regenerative thermal oxidation (RTO). In the design offered by CESCO, complicated valve technology is eliminated by a special air distribution system without expensive control technology.

Dual Stage Pyrolysis and Incineration System: the dry sludge granules are first introduced to pyrolysis, followed by incineration. The energy from the pyrolysis gas is used in the same process to dry the sludge. The process is perfectly suited for the thermal utilization of solid or semi-solid materials with a high heating value. In the dual-chamber rotary furnace, the “pyrolysis” step for the conversion of the waste into energy, is followed by the “incineration” step, which turns the waste into inert ashes to be safely disposed of.

Catalytic destruction of volatile organic compounds (VOC) contaminants in an air stream is a very economical solution to plant emission reduction. The process involves lower temperature operation than corresponding thermal options and often allows heat recuperation without requiring exotic alloys in the heat exchangers. This feature further reduces the comparatively low fuel consumption of the catalytic systems. While these economic factors have made catalytic systems attractive to the end user, the applications have been limited by the vent stream constituents that could be tolerated by the catalyst formulation. Catalysts used in VOC oxidation processes have had limited applicability because the catalyst could be deactivated by some contaminants, masked by some, and poisoned by others. The former limitations were so broad that only select applications were considered an appropriate fit. Aggressive research programs by catalyst suppliers have developed formulations to eliminate these limitations or render them less harmful.
Catalytic incinerators offer fixed-bed or fluid-bed systems and are used to combat VOCs (volatile organic compounds) and particulates. Industries such as petroleum, coal, chemical, primary metals, electronics, gas, sanitation, stone, clay, glass, mining, paper, surface coating and printing often rely on this method.

| Catalytic oxidation of VOC contaminants in a waste stream is typically performed with waste streams where the VOC concentration does not exceed 25% of the Lower Explosive Limit (LEL) and where the oxygen concentration of the flue gas is at or above 2.0%. The system is designed to raise the waste stream temperature to the design inlet temperature of the catalyst, typically 260-370°C (500-700°F), by a combination of fuel gas burning and heat recuperation. The catalyst outlet temperature is a function of the amount of heat available for release contained in the VOC, and the Destruction Removal Efficiency (DRE) required for the application. This temperature is usually limited to a peak value of 663°C (1225°F) . The exact amount of catalyst needed is determined by the DRE requirement and the exact VOC constituents being oxidized. More difficult constituents such as CH4, etc. require greater volumes of catalyst for destruction than do most longer-chained hydrocarbons.
