I forge with good quality processed coke and, like you, never get any clinker at all. In the days when you were allowed to burn coal in this country I used to get quite a bit of it.
The poor-grade anthricite that I use for heating the house produces a lot of clinker, but once it's cool it simply gets crushed up and goes out through the mechanical de-ashing system on the boiler.
So yes, a lot seems to depend on the fuel being burned.
With a bit of experience it's not that hard to spot clinker forming in the forge. It always forms in the same place, and shoving a cold steel poker through it will make it stick and pull out like so much toffee.
