That title ought to get some attention! *opens beer*
This may be a good question for @RayWohlfarth
and also reminds me I still need to get a copy of your Brewing With Steam book!
I work at a lot of breweries (on the boilers/burners) in the DC/VA/MD area and this is something I've wondered for awhile actually. They tend to run higher steam pressures for this process. And the kettles usually have an F&T trap on the outlets of the kettle jackets. There's one that has the kettle right next to the boiler. Steam goes up and into the kettle and the condensate comes out, into an F&T, and right into the feedwater tank. This particular one had quite a noticeable amount of flash steam coming out of the tank vent. I asked them when the last time they had their traps tested/serviced was. They told me the traps were only a week old and another company had replaced them because of the "steam" coming from the vent.
I don't know anything about brewing beer or kettles, but if it were being fed the correct amount of steam, maintaining whatever temperature it needs to maintain, would one assume the condensate would probably have cooled off enough after going through that process to not be hot enough to flash at the trap?
Another thing they brought up is, every time they shut the steam off to a kettle (motorized valve) they hear a loud pop as it cools off. The first thing I thought was the jackets imploding from vacuum forming. They didn't have any vacuum breakers after the motorized valves. It would be wise to use a vacuum breaker in this situation right?
Thanks for any advice!
Never stop learning.
