Organic waste gas concentration and heat storage furnace (RTO)

The principle of a thermal incinerator (RTO) is to heat organic waste gas to above 760 degrees Celsius, causing VOCs in the waste gas to oxidize and decompose 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", which is used to preheat the organic waste gas that enters later. Thus saving fuel consumption for exhaust gas heating. Ceramic thermal storage bodies should be divided into two or more zones or chambers, with each chamber undergoing storage in sequence

The principle is to heat the organic waste gas to above 760 degrees Celsius, so that the 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", which is used to preheat the organic waste gas that enters later. Thus saving fuel consumption for exhaust gas heating. Ceramic thermal storage bodies should be divided into two or more zones or chambers, with each chamber undergoing a sequence of thermal storage, heat release, and cleaning, repeating the process and working continuously.

System features:

(1) Adopting a thermal storage heat exchange device, the thermal storage carrier directly exchanges heat with the gas, and the furnace radiation temperature

High pressure, fast heating speed; The low-temperature heat transfer effect is significant, so the heat transfer efficiency is particularly high; Maximize the recovery of sensible heat from oxidation products. High thermal efficiency, low exhaust temperature, and significant energy-saving effect. Reducing fuel consumption also means reducing greenhouse gas emissions;

(2) The uniform and graded increase in temperature inside the heat storage chamber enhances heat transfer inside the furnace, resulting in a more efficient heat transfer. Therefore, the furnace volume of an oxidation furnace with the same processing capacity can be reduced, greatly reducing equipment costs;

(3) Due to the fact that the flame is not generated in the burner, but gradually oxidizes in the high-temperature heat storage body inside the furnace without a high-temperature front, the oxidation noise is low;

(4) Expanding the high-temperature flame oxidation zone, the boundary of the flame almost extends to the boundary of the furnace, thereby making the temperature inside the furnace uniform. This not only improves the purification efficiency, but also extends the furnace life;

(5) Different thermodynamic conditions from traditional combustion processes, using staged oxidation technology to delay the release of thermal energy during oxidation; Uniform temperature rise inside the furnace and low heat loss; Heating effect consumption. There is no longer a local high temperature and high oxygen zone that occurs in traditional combustion processes; Inhibited the generation of thermal nitrogen oxides (NOX), with good environmental protection effect;

(6) The temperature inside the oxidation chamber increases overall and becomes more evenly distributed; The furnace temperature can reach 760-800 ℃, with low airflow velocity and fast oxidation rate. The flue gas stays at high temperature in the furnace for a long time, and the organic matter is completely oxidized and decomposed. Significant environmental protection effect;

(7) The system adopts PLC automatic oxidation control, with high degree of automation, stable operation, and high safety and reliability;
