It's been a hot topic in boiler room facilities... electric or steam heat tracing?
Today on The Boiling Point, we talk with Rick Walker in the Valve Shop about how a relief valve works. Rick, a valve professional, explains that these giant valves for boilers and air receivers work on spring force. When the valve is in service and the pressure inside equals the spring force, simmer will occur, which is an opening up of the valve that diverts pressure. This process is accomplished with the assistance of performance rings. When the rings are not positioned properly, malfunctioning can occur in your valve.
The majority of boiler catastrophes are caused by human error. Improper installation, improper repair, low water conditions, operator error, and poor maintenance can cause boiler and pressure vessel incidents that lead to devastating consequences. At WARE, we want to educate our customers and anyone involved in the operation, maintenance, planning or purchasing of a boiler or boiler related equipment in order to prevent these catastrophes.
On this next "Hey Jude" installment of The Boiling Point, with the help of our man Jude, we are going help you know when your boiler traps have been properly tested.
Infrared guns are useful for taking measurements and determining if a trap is cold or hot, but it will not tell you if the trap is really working. Watch the entire video below to find out exactly how WARE determines what is going on inside your boiler traps, so that you don't replace them mistakenly or have to guess what's happening inside.
Thanks for tuning in to another edition of the Boiling Point!
In our next Boiling Point installment, we continue with our discussion on boiler combustion and efficiency. In Part I of this video series we learned why all flames aren't created equal and how we could learn to look for certain things that do indicate a properly functioning boiler. In this installment of the Boiling Point, we recap what we learned about boiler combustion in Part I and follow that up with a discussion on boiler efficiency and what that really means. If you missed Part I, you can catch that here.
A boiler cycle includes a firing interval, a post-purge, an idle period, a pre-purge and a return to firing. Boiler short cycling takes place when an oversized boiler quickly fulfills process or space heating demands and then shuts down until heat is required again.
Boiler efficiency can be calculated over the cycle duration by taking the useful heat provided by the boiler and dividing it by the useful heat plus losses. Boiler efficiency is reduced when short cycling occurs or when several boilers are operating at low firing rates.
Hollywood is notorious for factual inaccuracies in films, and in all reality, it simply comes with the territory. Heck, if they were to get everything correct down to the finest detail, the production cost would be so high that it would no longer be practical to finance movies. Besides that, the audience is often simply there to be entertained—who cares about some small details that don’t impact the story, right? The only time a factual error really raises a stir is when it seems so outlandish or impossible that it removes us from our immersion in the movie. Just think: if you saw a guy jump the Grand Canyon on a bicycle, wouldn’t your instinct tell you that what you were watching was a bit far-fetched? The mind can only take in so much before our “willful suspension of disbelief” is overruled by our logic.
