Gas sampling for cement kiln and calciner gas exit SCK
Data
The SCK consists of the following three modules:
- Probe retractor with pneumatic motor and chain driven water-cooled probe
- Control unit with industrial controller and touch panel operation
- Cooling unit with speed-controlled heat exchanger, closed water loop and cooling water circulation pump
Probe retractor
The retractor with its pneumatic chain drive carries the gas sampling probe. After the probe can be completely retracted, an integrated pneumatically driven oven flap closes the sampling opening, thus preventing hot and toxic gases that could cause hazard to operators and machinery to exhaust from the kiln. A complete top cover protects the moving parts from dust. Due to the design of the retractor, the tip of the probe is available for inspection and cleaning purposes at all times.
ABB is the only supplier on the market that can offer two different water cooled probes for the kiln application:
- Probe H is preferred where extremely hard encrustations are to be expected. The pneumatically driven plunger, which is welded on the filter tip, mechanically breaks the encrustations at the probe gas entry without interruption of the measurement
- Probe 60S is the choice for kilns where extremely hard encrustations are not expected
Length:
L = 1.5 m / 2.0 m / 2.5 m preferably for use at calciner gas exit
L = 3.0 m / 3.5 m preferably for use at cement kiln gas exit
