They are using the lake source cooling system to heat the buildings now.

Using deep Cayuga lake water for cooling and return it to Lake. I love that kind of stuff

I was in the second grade when they made that dumb mistake.

This "lake cooling water distraction" cannot help this fellow in Ontario wanting to use coal to heat and circulate hot water... :roll:

BTW: It is not recommended to allow returning water to a boiler at a temperature of less than 140*F. So it is best not to advocate that anything less is acceptable to those who are unaware.
Coal exhaust gas paths passing over steel or iron surfaces maintained at less than 140*F will allow for acidic condensates to begin the attack of the iron on contact. It takes a while to see the effects, but by then it's too late.

My return water is 120 degrees+- and the hot water in the steam chest is 140-160

How did the subject get changed to steaming the lake ?? :?

Well... storage tank.... those massive tanks used in that school were not saving coal,they were there to even out the peak demand loads that can easily happen in a big system like a school,where demand can go from light to outrageous in a minute.

I did not know it at the time when I checked the boiler temperature in the return line but when I mentioned the 120 degree figure at that time I had an out fire.

I still have my high limit set at 160 degrees Fahrenheit and low limit set at 140 degrees

Yes, McGiever you'are right.
Difference between outgoing and returning temperatures shouldnt exceed 15-20 degrees, otherwise boiler might crack. Especially those made from plain iront. Cast iron can handle some bigger temp difference, but i wouldnt try it anyway :-).
I would try to set up temp as high as i can but below boiling point of course....

Hello Polarlight,

If you install storage you can use a second circulator like the B+G NRF25 with three operating speeds to maintain a higher balance temperature between the tank and the coal stoker using a lower summer operating temperature 160 low 180 high and also have the storage buffer tank as the dump zone without actually requiring one.

In my old system I had a second circulator that was employed to move the heated water between my hand fed boiler and the oil boiler that operated continuously and the oil boiler only operated when the hand fed boilers temperature went below the set minimum temperature that was controlled with a triple aquastat in the top tapping of the Buderus oil boiler I had.

If you use the $15.00+ Insulated pex with closed cell foam you will have little heat loss.

Hello Azaharis,
I am not installing any storage tank at least now. Later may be, notsure.
I do not have enough room inside. Need to keep all my toys and other stuff like lawn movers inside my boiler' s building. Next week i will be working on chimney, then busy with reinforcing wall where all pipes with pumps gonna be. The same wall going give support for the chimney, which is double wall with insulation inside.
Chimney is quite tall about 50 feet hight and 1' outside diameter. So, I am planning to support it with guywires if it works. The next step going to be pipes & pumps. I am still thinking about design and everything....

The another problem i have in mind.
Boiler is too havy to be moved around. Empty it weights around 1250. So, I am planning to jack it up, remove pallet underneath, then use some sort of trolley to move it around before i can drop it for a final destination. Where i can connect to chimney, hopper with auger and set of pipes. ...

Hello Polarlight,

If you have a rental store nearby you can rent an engine hoist to lift the the boiler off the pallet if it has a lifting eye. Some folks use a heavy schedule 80 T and nipple to lift and lower their boiler into basements from the floor above or through a bilco basement door.

Just keep in mind that the boiler is probably bolted to the pallet so you will have that to contend with.

If the boiler is bolted to the pallet you can put the lifting straps through the both sides of the pallet and then hook them all together on the engine hoist hook and move the boiler where you want to set it in the garage and remove the pallet from the bottom of the boiler and then lower the boiler down and set it on the concrete blocks and go from there.

Do you know if the pressure vessel and the ash pit are 2 piece arrangement or are they welded together like some boilers with a steel floor?

Ash pit located in the same box, just below where the fire is.
I am thinking about using the engine hoist and straps. But boiler is too high because it sits on a pallet. Almost 7' high. May be pulljack can help?

I invested in a pallet-jack, a few misc. plastic pallets and some IBC totes. No regrets, very handy to have around.

Many times I have rolled heavy items onto plastic pallet(s) to jockey around items and then the IBCs can hold around a ton of coal to be jockyed also. I cut the polyethylene tote to be able to add coal by chute from elevated truck position. As well I added a slide gate to open and close coal exit at bottom for my AA auger. There were times I loaded drums or barrels on pallets to be moved around also.

Just food for thought. ;)
