Solutions Of Regenerative Thermal Incinerator (RTO)
RTO is an efficient organic waste gas treatment equipment. Compared with the traditional catalytic combustion and direct-fired thermal oxidation furnace (TO), it has the characteristics of high thermal efficiency (> 95%), low operating cost, high air volume and low concentration exhaust gas. When the concentration is slightly higher, it can also carry out secondary waste heat recovery, which greatly reduces the cost of production and operation.
RTO (Regenerative Thermal Oxidizer) is a regenerative oxidation furnace. Its principle is to oxidize the flammable exhaust gas into corresponding oxides and water at high temperature, so as to purify the exhaust gas and recover the heat released when the exhaust gas is decomposed. The decomposition efficiency of the exhaust gas is over 99%, and the heat recovery efficiency is over 95%. The main structure of RTO is composed of combustion chamber, ceramic packed bed and switching valve. According to the actual needs of customers, different ways of heat recovery and switching valves are selected.
Its principle is to heat the organic waste gas to more than 760 degrees Celsius, so that VOC in the waste gas is oxidized and decomposed into carbon dioxide and water. The high temperature gas flow produced by oxidation, a special ceramic regenerator, warms up the ceramic body and "regenerates heat", which is used to preheat the subsequent organic waste gas. Consequently, fuel consumption of exhaust gas heating can be saved. The ceramic regenerator should be divided into two or more zones or chambers. Each regenerator should work continuously from cycle to cycle through the procedures of heat storage, heat release and cleaning. A proper amount of clean air should be introduced to clean the regenerator immediately after the regenerator "releases heat" (to ensure that the VOC removal rate is above 95%). Only after the cleaning is completed can the regenerator enter the "regeneration" process.
