chuck shaw

Yep

My brother had one installed over 20 years ago to replace his old asbestos covered monster.

He also runs a superstor off it for dhw.

Hey Chuck,

We had a ton of these at the old company. Glen-Mor (which is now Petro/Meenan) were installing them in the mid 80s.

When I first started they thought noone would touch a Riello burner and they would have the market sewed up. OOPS! Guess they were wrong on that one.

Nice running unit too. Three pass heat exchanger made for some great combustion numbers. Chris

If I remember right the header was only 1 1/4. You needed a tight system or they would always be running out of water. If everything was good they ran well

Chuck, those were

made at Pensotti in Legnago, Italy on my specific request. We sold a bunch of them and as people have eluded here they were not really steam boilers, but generators.

In Commercial applications they had to have an external steam drum to process the heat much like the older pork chop design, aka Smith Mills, does it.

I was always disapointed that these boilers were dropped by the purchasers of Pensotti, but the family had more imagination, JMO!

It's also been discouraging not to see any new steam technology built into the state-of-the art stuff out there now. When you look at the number of steam boilers sold it's quite amazing and not everyone can convert to water.

But, when you consider wet heat in all of it's forms is only 6% of the US market, well...............

If you'd like to see a picture of a Commercial unit I'll try to post it, have dozens of old Pensotti shots from my Belcher days.

that's wild....

what a drop header would do for that. I would love to see a commercial one George. The water content would be an issue...it would not take long to get it steaming. Near boiler piping would really be critical. kpc

three pass heat exchanger

Does that make this boiler a "mini" fire tube boiler?

This is a question I've had for a long time: Would a mini 3 pass fire tube boiler with a modulating forced induction burner not be the bee's knees?

If so, is there anything like that out there? Such a thing would likely get me more excited than I'd care to admit...

I've had a three pass

boiler like the one shown with a two-stage residential, burner lo-hi-lo in my home since 1985. It's the nuts, FACT!

Finally got the parts together and this Spring we're going to rebuild it with the major parts. New pump, chassis, fan, motor, air-tube etc.

After saving me a ton of oil and never breaking down I figure it deserves the bone-yard. RIP, it deserves it.

BTW, over an identical single-stage burner the savings averaged 15% per annum.

You're right on all points

Kevin and now that I've put my foot in my mouth again, I'm trying to find my albums. They may have made the warehouse or still be here in this disaster area I call an office.
Hmmmm, I wonder if I could apply for Federal aid?

Dope slap For me.....

Sorry George, I forgot about Belcher. When I started, they were only around for about 1 1/2 years. We used to call them "tee pee" boilers. I bet there are still 90+ % of them running out there.

Wish I had delved into steam far enough to have learned about drop headers back then. I bet with a big upsize at the top of "demesion A" and a matched size to the takeoff piping these would have been the nuggets!

Keep us informed on your new endevour. I'm SURE you'll be telling us about it at Brookhaven(?). Chris
