Technical Introduction of Regenerative RCO Catalytic Combustion Equipment


Regenerative RCO catalytic combustion equipment is developed on the basis of regenerative incineration. The biggest difference between the two is the oxidation temperature. High temperatures above 800°C will produce NOX secondary pollutants; RCO only needs a temperature between 300-500°C, so RCO is more energy-saving, safe, and does not produce NOX.


The regenerative RCO catalytic combustion equipment method is one of the combustion treatment technologies. The principle is to completely oxidize the pollutants under the action of the catalyst at a certain temperature, and the removal rate can reach more than 99%. This technology uses multi-bed catalytic chambers made of heat storage materials to switch between heat storage and catalytic oxidation, thereby greatly reducing heat losses. The main difference from direct combustion and catalytic combustion is the type and efficiency of waste heat recovery. Generally speaking: catalytic combustion is 30-50%, direct incineration is 50-70%, and RCO is as high as 90%.


The heat recovery method of regenerative RCO catalytic combustion equipment belongs to thermal regeneration, which uses the high thermal conductivity characteristics of ceramic materials as a heat exchange medium to obtain relatively complete thermal conductivity. After the exhaust gas containing malodorous gas or VOC is preheated by the ceramic packed bed for recovering waste heat, the temperature of the exhaust gas almost reaches the set temperature of the catalytic chamber and oxidizes the pollutants, and then it is introduced into the heating chamber to increase the temperature and maintain the set temperature to achieve a predetermined removal efficiency. The catalytically treated exhaust gas is introduced into other ceramic packed beds, and the heat energy is recovered and then discharged to the atmosphere. The discharge temperature is only slightly higher than the temperature before the exhaust gas treatment. Regenerative RCO catalytic combustion equipment All ceramic packed beds are used for heating, catalytic purification and heat storage cooling cycle steps. The technology has the characteristics of high purification efficiency and low operating cost.
