3: Use 10mm wrench to adjust position of the reveiver unit. (Version with upgraded purge air flow pictured).
Main alignment adjustment should be done from transmitters installationg flange as shown
on pictures 1 and 2.
As the laser beam is very compact, only small hol
es (10…50 mm dia) to get beam through,
are needed. Normally there is a small under pressure inside the stack, and outside air auto-
matically keeps the holes clean. In case there is overpressure in the stack, but source and re-
ceiver can be flange-mounted. Then, using the instrument-air purge system to slightly over-
come stack pressure keeps the instrument clean and functional.
The mounting system obviously varies from case to case. Basically there are three different
mounting systems:
a)
Mounting in the stack itself by L-type supports
b)
Mounting on the support structures (or on the floor/roof) around the stack. In this case
possible temperature related movement of the stack may require elliptical holes in the
stack.
c)
Mounting on the flanges welded in the stack. This case provides a solution, when
there is overpressure in the stack and gas escape from small holes is not allowed.
A specific problem appears when the dust content is very high. Then you might need to short-
en the laser path by horizontal tube inside the stack. As a rule of thumb, 1 m distance is
enough for concentrations 1-5 g/m

. Higher concentrations need shorter path.
