Rotating Regenerative Thermal Oxidation Furnace Equipment(RTO)

Introduction to Regenerative Thermal Oxidation Furnace System

The principle of Regenerative Thermal Oxidizer (RTO) is to heat organic waste gas to above 760 ℃ for a residence time of no less than 1 second, so that VOCs in the waste gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and "store heat". This "store heat" is used to preheat the organic waste gas that enters the furnace later, thereby saving fuel consumption for waste gas heating and reducing operating costs. The chemical reaction equation is as follows:

Cn Hm+(n+m/4)+O ₂ 850 ° nCO ₂+m/₂ H ₂ O+heat

Principle Introduction

Rotary RTO, also known as 12 chamber RTO, consists of a combustion chamber, 12 independent ceramic heat storage chambers, and a rotary steering valve. By rotating the rotary steering valve, the airflow direction in different areas of the ceramic thermal storage bed can be changed, thereby continuously preheating the VOC exhaust gas. After oxidation and combustion in the combustion chamber, VOCs can be removed. Compared to valve switching RTOs, rotary RTOs are more reliable in operation and have lower maintenance costs due to having only one movable component (rotary steering valve).

The rotary RTO mainly consists of a combustion chamber, a ceramic packing bed, and a rotary valve. The furnace body is divided into 12 chambers, including 5 inlet chambers, 5 outlet chambers, 1 cleaning chamber, and 1 isolation chamber. The exhaust gas distribution valve is driven by a motor to rotate continuously and periodically. Under the action of the distribution valve, the exhaust gas slowly switches between the 12 chambers.
