I am investigating what would be the most appropriate compressed air source (fan/blower/compressor) for designing a separate air compressor system.
The information is as follows:
the compressed air would be supplied to the lens of an industrial sensing instrument, which is mounted onto a pipe leading into a boiler's furnace
there are 12 instruments on each row and there are four rows in total (first row starts at 20m and there is an increase of 5m per row).
to provide sufficient pressure in order to prevent accumulation of dust on an instrumentation's lens
to provide sufficient flow to keep the entire pipe free of contaminants in the first place
- flow (800 m3/hour) for all 84 instruments (100 m3/hour for one row of instruments) (8.6 m3/hour for one instrument)
- pressure (40 mbar)
I know that the pressure demand is very little, it simply needs to be slightly above the furnace pressure. However, my concern is that the fans we have been using have not been able to provide sufficient pressure. Meanwhile, the flow is quite large.
Therefore, I am contemplating between a blower (more powerful fan) or a compressor (not sure if an air receiver would be necessary).
Which one would be more suitable (for both 100 m3 per hour and 800 m3/hour)?
What are the pros and cons of either (in terms of cost and space required and efficiency).?
If a compressor, which type of compressor (positive displacement, rotary, reciprocating) would be suggested?
Also, the duty cycle is 100% (all the tube needs to be cleaned at all times). If a compressor is used, is a receiver necessary?
How many instruments could be fed with one compressor?
