Herding ALPHA Filter up to 450°C/842°F
Description
The Herding® ALPHA filter element consists of a high temperature resistant inorganic filter media. The maximum operating temperature reaches up to 450°C (842°F). ALPHA filter have an excellent chemically resistance, even at high temperatures
The cylindrical shaped basic elements (filter candles) are coated with an also inorganic layer on the outside, in order to separate finest dust particles by pure surface filtration
The filter media have an excellent thermal shock resistance
These basic elements are mounted in a stainless steel support frame to cluster
The internal as well as the external gasketing of the Herding® ALPHA filter element (cluster) is made by high temperature resistant inorganic fiber materials
The internal gaskets are clamped by springs made of high temperature resistant special material
In the filter unit the Herding® ALPHA filter elements (cluster) are mounted vertically from the clean gas side
Benefits
- Constant filtration performance at low pressure drop
- High filtration efficiency and long life cycle
- The filter is always cleaned online with jet-pulse, also with inert gas
- The long term thermal stability is 450 °C (842 °F) also in an oxidative atmosphere
- At start up and shut down a high temperature gradient is possible in order to pass dew points rapidly
- Incombustible, very good chemical resistance
- Easy filter element assembly, no single filter candles or loose gaskets
- Compact design, large filter area in comparison with the construction volume available
Specifics
- Dedusting of producer gas at the thermochemical biomass gasification
- Off gas dedusting of combustion processes
- Off gas dedusting of melting furnaces
- Separation of solids out of hot process gases
- Pneumatic conveying at high temperatures or of hot bulk
