A visit to Troy Boiler Works EVO World

[Bob Rohr]

I had a chance to visit this old, 1863 est. shop today. They are building the Austrian designed pellet and chip boilers here. Quite the shop that builds all sorts of large steel vessels. The boilers can be built to fire pellets or chips. Several large boilers were being built some in high cube containers for commercial jobs around NY State. They also roll steel and build the large buffer tanks.

Very stout construction, turbulators built on a rocker system and self clean. These boilers are built like a tank. The smallest looked to be around a 40KW

Lou Okonski showed us around. His dad bought this business in 1948 and in his 80's still tinkers in the shop. He is working on a rig to dry chips under a vacuum. A pellet boiler adds some heat, pulling a vacuum allows the moisture to boil or flash at low temperatures. In a near perfect vacuum you could boil water at around 76F.

Same concept is used in evacuated tube solar collectors, the fluid inside, under a vacuum boils somewhere around 100F.

It's nice to see these boilers being built to very high standards here in the US. The ASME versions track every piece of steel to the manufacturer, welds inspected and certified.

Thanks, looks like good solid stuff...

Looks like they've made progress since I was there last year:

There was a TV blurb on them the other day on a local station.

Yeah, good to see US manufacturing getting on top of this.

Are those units human or robot welded?

 

[velvetfoot]

Human.
edit: I think.
