If you had to describe a boiler (PAH)

Dave Yates (PAH)

what would you say? Not as easy as it sounds at first glance(G).

So whadda you tell the young squirt? No system stuff, just a basic understanding of what a boiler is!

Must include both steam and hot water boilers for residential, commercial and power plants!

A heating apparatus designed to heat fluid--typically water. If water, it is heated either in the solely liquid state or from water to water vapor. The energy produced by a boiler is used either for heating or mechanical energy in any number of applications such as space heating, cooking, cleaning, electrical generation, motivation, etc.

a containment field for combustion,where the heat

is exchanged from the fire to a medium that is then able to be redistributed for a variety of human needs . under the heading of food clothing and shelter the applications are many. for your next assignment please give 5 examples of these applications and we will take a quick consensus of the ones most commonly thought help aid human beings in the pursuit of their lives *~/:)

and have a few they never heard of ready to confuse the heck out of them

Holohan described it once as just a hot spot in the pipe.

simple just tell him a boiler a something that's used to heat water witch is then pumped to radiators or baseboards and hydro air coil's.

also let him know what's used to heat the water in the boiler burner,gas,oil,propane,wood,coal,ect

and showing him pictures will help him understand allot because he can point to things and say whats that do. pictures speak a thousand words.

good luck

In the beginning...

there was cold, and darkness.

Begin with the story of Prometheus. "Prometheus had stolen fire from Zeus and given it to the mortals in their dark caves. The gift of divine fire unleashed a flood of inventiveness, productivity and, most of all, respect for the immortal gods in the rapidly developing mortals. Within no time (by Immortal standards), culture, art, and literacy permeated the land around Mount Olympos (Olympus)." 1

Contrary to popular wisdom, taming fire is the oldest profession, because before fire there were no professions and there was no civilization.

Huddling around a fire, carrying a burning branch or a hot stone, realizing that heat can be carried by inanimate objects--by fluids (water, air), which can be piped.

The rest of history is finding different ways to make fire, to safely contain it (still working on CO detectors, etc.), to move the heat and energy.

Dave, you know this modern technology. If I were in the 8th grade, I'd be impressed that this is man's oldest pursuit--the quest to tame fire and provide comfort...

How about this?

Tell him it's a water filled coil with fire heating it up.
If he asks more questions, give him more details. It depends on how much he wants to know. It reminds me of a kid who asked his parents "where he came from."
They gave him the big birds and bees story, to which the bewildered youngster replied, "OH,... Jimmy's mom said he came from Chicago." Kevin

It's a box...

usually made out of metal, with another metal box inside of that box. Inside of the middle box is a fire. This fire generates heat, which transfers through the walls of the inner box to the surrounding water between the two boxes, heating the water. It has pipes connected to it to convey the heated fluids out of the box.

If the fire is turned off before the water reaches 212 degrees F, then it is a water heating boiler. On this type of heating system, there are other boxes, which look like the fire box except turned inside out. These are called radiators. Their job is to radiate heat into the room to create comfort.

Now, if the fire box boiler is allowed to raise the water temperature to hotter than 212 degrees F, then it is a steam boiler. Again, that heat can be used inside of a radiator to create comfort. It is usually only allowed to generate 1 or 2 pounds of steam pressure in this situation.

If the water surrounding the fire box is allowed to get REAL hot, say 250 degrees F, then the steam pressure, say around 100 PSI, it's generating is strong enough to move pistons inside of an engine, and that movement is converted into other useable forms, like electrical generation, or running a conveyor belt, or cotton gin mill.

Remember guys, we're talking 8th graders here, not pre grad rocket scientist :-)


How'd I do prof?

Ya done good!

Been beating my brains out over this one for weeks! It's a one-shot deal where no pics can be used and it's supposed to be written at the 8th grade level. I finished it this afternoon. Curious to see if I came close to the mark & thought I'd task folks a lot smarter than me, ME, to get their views.

The real challenge, for me, was keeping the perspective of "talking" with a youngster while not talking-down to them or talking-up and losing the audience by using words or phrases only someone already familiar with boilers would use - boiler speak!

Kind of like describing sight to a blind person, or the sense of touch to someone without fingers! Been pounding the keyboard all weekend(G). I've edited and re-edited the piece so many times, I can't hardly focus on the screen anymore. I'm trying to convey the excitement of hydronics at the same time & hope they'll be enticed to delve a bit deeper into the new hydronics. The original piece looked like it was written when steam was king & barely touched on hydronics.

The hell of it is I'm limited to 450 words! Stuffing steam and hydronics into a 450 word box is not fun

when humans learned of fire

They said "this is really great." Right after choking on all the smoke that came off the fire. So time want by and the idea of a chimney came about to separate the fire from the smoke. This was a big improvement, but it still meant you needed to have a fire everywhere you wanted to be warm. Still not satisfied, people continued to tinker with how to separate the warmth from the fire.

That's what a boiler does, it allows you to separate the heat from the fire. One they are separated, you need some way of moving it around. Since there is always loads of water around and it absorbes and releases heat well, it was a natural choice.

Looking at this boiler, first we need to create the fire. We can mix air with gas, oil, wood, corncobs, etc. and set them on fire. People made nuclear reactors to make the heat and others are trying to make the heat like the sun does. You can even focus the suns rays and push that heat into water to move somewhere else. You can either heat up the water as a liquid and pump it, or you can heat it until it boils and move the steam.

Once you have this heated water or steam, we get to figure out what to do with it. One of the first things was to make machines that turned steam into motion. These have been hooked up to pumps, propellers, locomotives and electric generators to name a few.

Another thing is to use the heat in the water/steam is to heat a builing....

I can't get my writing UP to 8th grade level, tried it once..teacher thought my kid became stupid..oh well

I would, but...

I can't. I don't have the copyrights for the work & had to agree to that prior to the assignment. Can't say who it's for just yet either.

I guarantee

that if describe as a "pot" you'll get the 8th graders attention
