Working principle

Direct-fired incinerators can be comprehensively designed based on the volume, composition, concentration, and required removal efficiency of the exhaust gas to be treated. The furnace is heated to a set temperature using fuel, after which the exhaust gas to be treated is introduced. At high temperatures, pollutants such as VOCs oxidize and decompose into CO2 and H2O, releasing a significant amount of heat energy. The heat energy carried by the purified high-temperature flue gas can be recovered through external equipment like heat exchangers and boilers, achieving energy savings and reduced consumption. When the concentration of the exhaust gas to be treated is sufficiently high, zero fuel input can be achieved, as the heat generated by the oxidation of the exhaust gas itself can maintain the furnace temperature, thus achieving heat self-sufficiency.

Applicable Scope

1. Working conditions with high removal efficiency requirements.

2. The concentration of waste gas to be treated is very high, and conventional RTOCO cannot cope with the working conditions.

3. There are many sources of waste gas, and the discharge air volume, composition and concentration vary greatly under working conditions.

4. The waste gas contains salt and halogen, so it is not suitable for the operation condition of incinerator with complex structure.

5. The waste gas contains particulate matter and adhering substances, so it is not suitable to use the furnace type that is easy to block with heat storage bodies and catalysts.

6. The owner has the need for steam, heat transfer oil and other by-products under working conditions.

7. The operating stability of the incinerator system has high requirements.

Characteristic

1. The removal efficiency is up to 99.9%.

2. Wide range of application, it can deal with high concentration of waste gas, salt & halogen and other complex working conditions of waste gas.

3. Flexible system design and wider range of materials selection.

4. Heat recovery devices such as heat exchangers, steam boilers and thermal oil boilers can be flexibly configured outside the furnace.

5. The furnace structure is simple, the shape is diversified, and it can be customized according to site restrictions.

6. The retention time in the furnace can be customized according to the needs, with good design flexibility.

7. The incinerator has fewer control components and low failure rate, which can reduce maintenance costs.

8. Waste gas and waste liquid mixed combustion incinerator can be configured according to customer needs, with multiple uses in one furnace.

9. For the exhaust gas containing particulate matter, the heat exchange equipment can realize online cleaning without affecting the normal operation of the device.

10. SNCR desorption module can be integrated in TO furnace according to customer requirements.
