Waste gas incinerators, also known as RTO (Regenerative Thermal Oxidizer) systems, are environmental protection facilities that decompose harmful gases through high-temperature combustion. Their operating principle is to use the heat generated by auxiliary fuel combustion to raise combustible hazardous gases to the reaction temperature, where they undergo oxidative decomposition, thereby achieving exhaust gas purification and emission reduction.
With the continuous advancement of incineration technology, modern waste gas incinerators increasingly emphasize resource recovery. By reclaiming the waste heat generated during combustion for power generation or the production of superheated steam, these systems can meet on-site energy demands while significantly improving overall energy utilization efficiency, thus promoting green and sustainable development.
In terms of insulation structure, RTO furnaces have gradually shifted from traditional castable linings to lightweight ceramic fiber linings with superior energy-saving performance-namely, composite insulation structures based on ceramic fiber modules. The following example illustrates a typical RTO project and its application:
Project Type: Regenerative Thermal Oxidizer (RTO) for waste gas treatment
Furnace Dimensions: Length 6.42 m × Width 1.74 m × Height 4.325 m
Operating Temperature:
Upper combustion chamber: maximum 850 °C
Lower regenerator chamber: maximum approximately 750 °C
Insulation Objective:
Ceramic fiber insulation materials are used to ensure that the external surface temperature of the furnace wall does not exceed 60 °C after insulation, achieving high energy efficiency and long-term durability of the lining structure.
