HeatMatrix - Regenerative Thermal Oxydisers (RTO) and Incinerators
Cold spot corrosion problems and mechanical failures limit heat recovery on Regenerative Thermal Oxydisers (RTO) and Incinerators. Polymer economisers and air preheaters are corrosion resistant and designed for leak proof thermal expansion.
Your Regenerative Thermal Oxidizers (RTO) and Incinerator have waste heat recovery potential
Improve thermal efficiency
The thermal efficiency can be improved by using a polymer air preheater or economiser.
Lower CO2 emissions
Every 1% efficiency increase results in 1% CO2 emission reduction.
Decrease fuel costs
By recovering additional waste heat, less fuel is needed to achieve the required conditions in your RTO or Incinerator.
RTO’s and Incinerators are used to oxidize pollutants that can be present in off-gas streams. Many RTO’s or Incinerators have a high fuel demand. Even though heat recovery is already applied, substantial energy losses still exist.
Depending on the flue gas composition, heat exchangers may suffer from cold spot corrosion due to relatively cold tube skin temperatures. This limits heat recovery. Enhancing further thermal efficiency is possible by installing a corrosion resistant air preheater or economiser which recovers additional heat from the flue gas. This results in extra energy savings.
Conventional heat exchangers suffer from mechanical failure due to stresses that are developed by thermal expansion. This results in leaking equipment and loss of heat recovery.
The simplest and most economical way to improve the efficiency of your RTO or Incinerator is by applying an economiser to preheat boiler feed water or process water. In case of flue gases with high acid dew points the stainless steel or polymer economiser of HeatMatrix is applied. This economiser is insensitive to acid dew point corrosion and can recover energy from your flue gas under harsh conditions.
Preheating the off-gas entering the RTO or incinerator could be an alternative usage of the flue gas heat. The HeatMatrix air preheater is used for this purpose.
