Especially for special applications
It sounds double, but it's true: we have developed our KVA catalytic incinerators especially for smaller special applications. And they have proven to be particularly economical in all these cases. Especially with known and consistent pollutant loads. Exhaust air containing silicon or phosphorus cannot generally be treated. The possible applications for other critical substances - such as sulphur - must be examined on a case-by-case basis.
Effective and customized - the choice of catalyst
Whether precious metal catalysts, mixed oxide catalysts, bulk material pellets, ceramic honeycomb bodies or metal foils as carriers - we work closely with renowned catalyst manufacturers in the development and production of our catalytic incineration systems. This means that the catalyst is always selected based on an analysis of your individual requirements profile. You can be sure that you will receive the optimum solution in terms of design and process technology.
Catalytically efficient - the process
The operating principle of catalytic incinerators is similar to that of our thermal incinerators. As a rule, a recuperative heat exchanger preheats the exhaust air. Then, if necessary, a support burner or electric air heater brings it up to the required reaction temperature. In contrast to the purely thermal or regenerative processes (TVA, RVA), in catalytic incineration plants (KVA) a catalyst reduces the reaction temperature to approx. 300°C to 600°C, depending on the application, in order to convert the pollutants into CO2 and H2O. The solvent conversion at the catalytic converter additionally heats the exhaust air. Heat exchangers feed this otherwise unused excess energy back into the exhaust air preheating process. Ideally, this process therefore achieves almost autothermal operation. However, certain substances - such as silicon compounds - can impair catalytic converter activity. This is the reason why we take particular care to investigate pollutants when planning your system. We take a very close look.
Reduces your costs, increases your flexibility - the advantages
Above all, catalytic incineration systems bring significant cost savings. The low reaction temperatures have a positive effect on your operating costs.what else do you get out of it? Flexibility in many respects:
- You get a variable design adapted to the optimum catalytic converter in each case.
- We also offer small sizes for low air volumes. These are also available as completely pre-assembled units ("plug and play").
- Our catalytic combustion systems can also be used where no gas supply is available for a back-up burner.
