does anyone have vintage pre-1987 central air condtioners, forced-air gas furnaces, and thermostats?

Hmmm I would have assumed that air-shutters for coal burning are non-electric and use a bi-metal thermostatic damper control. Unless there was an auger-screw electric coal-feeder coal burning was not normally electrically controlled/regulated, IMHO.

The beauty of coal-burning steam-generating central heating systems systems (as were typically found in NYC) is that they were totally non-electric.

I would further assume these pictured to be electrically operated and for a gaseous or liquid fuel.

Gas burning conversion heads are known as power-burners (they look like oil-burners)and deliver a ball-of-flame in one location rather than a more typical designed-for-gas furnace or boiler which has a number of gas burning tubes or jets that spread out the flames. The power burners typically have a fan to push secondary combustion air into the combustion chamber, and to induce a positive draft. Of course the (non-powered) gas venturi used to mix in primary air for combustion is normally outside the combustion chamber.

Well, it's sixty years later, and I'm certainly no h

The conjectures I made earlier are just that -- conjecutes. I love interesting old buildings and the interesting old equipment you find in them. I guess I just associate the little swinging doors with the sliding vents with solid-fuel type burners.

It also seems obvious that the blower shown at the bottom was added later. Both the apparently added-on, welded brackets and the fact that the blower blocks the boiler-room door so that it can't open fully lead me to this conclusion.

This thread has prompted me to do a little exploring once again, and I can't see any obvious location for coal storage. Of course, the passage of time can obscure a lot.

And Toggle, I guess you're right. One could break the boiler into pieces and carry it out that way. I just can't imagine doing such a thing to anything this impressive (and scary). I spend much of my time fixing and preserving. Destroying isn't an option I usually consider.

Found a minty Honeywell rectangular institutional type thermostat in my shop the other day.

If anyone expresses the slightest amount of interest, I'll post a photo.

post away! I'm interested.

It's a "Minneapoli-s-Honeywell"...

It's the kind that you can render unadjustable by general employees or public... you know, the kind you love to hate if it's too hot or warm inside...

Will post pics tomorrow. It's kind of cool, in that it's built like a brick and has a bellows inside... I gather it's a line voltage operated unit.

Inside the beast

Note that the tempeature adjustment knob is removable ("security"), and the copper bellows. The thing is very solid - the black base is real bakelite.

I put "security" in quotes because I found a simple allen wrench in my desk that opens up the thermostat, and it also fits the temperature control adjuster perfectly. But I guess in its day the mfg didn't expect the average office or factory worker to figure that out... lol...

I do its a 1978

the oil furnace I have & still use here at my home you can see it in the right hand of my living room its a Lsi seigler

Thanks fo posting Rich and Gocart

How does that thing burn oil? I'd be interested, please, in the details of the oil-burning "head" or apparatus. Does it have to be ignited manually?
