Catalytic incinerators from Venjakob
Specially designed for special applications
That sounds like we’re just repeating ourselves but actually, no: We have developed our catalytic incinerators (KVA) especially for smaller special applications. And they have proven to be particularly cost-efficient in all of these cases. Especially for handling known and consistent pollutant loads. Exhaust air containing silicon or phosphorus generally cannot be treated. The options for use with other critical substances – such as sulfur – must be examined on a case-by-case basis.
Effective and tailored to your needs – the selection of the catalyst
Whether precious metal catalysts, mixed oxide catalysts, bulk pellets, ceramic honeycombs or metal foils as carriers – we work closely with renowned catalyst manufacturers in the development and production of our catalytic incinerators. Therefore, the selection of the catalyst is always based on an analysis of your unique requirement profile. You can be sure that you will receive the best solution in terms of design and process technology.
Efficient catalysis – the process
The operating principle of catalytic incinerators is similar to that of our thermal incinerators. Usually a recuperative heat exchanger preheats the exhaust air. Then, if necessary, an auxiliary burner or electric air heater brings it to the required reaction temperature. In contrast to the purely thermal or regenerative processes (TVA, RVA), in the catalytic incinerators (KVA) a catalyst reduces the reaction temperature to approx. 300°C to 600°C (570 to 1110°F), depending on the application, in order to convert the pollutants into CO2 and H2O. The solvent conversion at the catalyst heats the exhaust air even more. Heat exchangers feed this otherwise unused excess energy back into the exhaust air preheating system. Ideally, this method makes practically autothermal operation possible. However, certain substances – such as silicon compounds – can impair catalyst activity. This is the reason why we take special care when researching pollutants while planning your system. You can trust that we’ll be thorough.
A clear focus on pharmaceuticals – the areas of application
Catalytic incinerators are primarily used in the pharmaceutical industry. However, this method is also sometimes used in the foundry industry, in paint production and in wire coating.
Reduces your costs, increases your flexibility – the advantages
Catalytic incinerators are primarily a huge cost saver. The low reaction temperatures have a positive effect on your operating costs. And what is their other advantage? Flexibility on multiple levels:
- You get a variable design adapted to the optimal catalyst for each application.
- In addition, we offer small sizes for low air volumes. These are also available as fully factory-assembled units ("plug and play").
- Our catalytic incinerators can also be used where there is no available gas supply for an auxiliary burner.
