AquaHot Furnace vs Hot-Water?

The new water jet machines use high pressure water to cut steel.
I'm sure over time the diesel wears the nozzle larger. That's why they recommend changing the nozzle yearly.

Just had to change our nozzle yesterday. I had the entire into rebuilt 5 months ago. I was surprised that after just over 200 hours it was smoking do bad. Raw fuel around the nozzle. New nozxle cleared up the smoking.

Was the nozzle on there tight? Recall last time I changed mine out they suggest you tighten, loosen back off, then re-tighten.
5 months seems like a pretty short life, even if you are F.T!

Even "the old" water jet machines use water at high pressure to cut steel. lol
The concept (liquid ablative blasting) has been used since early '50s, and ultra-high pressure (100,000 psi) machines since the '70s. However, for water to effectively cut hard material, it is necessary to include an abrasive component in the water stream. Orifice wear in those nozzles of course is critical, and it was during the '70s that a ceramic material (aluminum oxide) was used - nozzle wear was effectively controlled. Various materials are used nowadays, including synthetic diamond.

I realize that no one asked, but what the heck... I thought I would share some history.
