STOKERS RUN TIMES and HOUR METERS

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

What are they useful for?
Who has them and who wants them?
How does one go about getting and installing one?

I have an hour meter wired in with the stoker motor. I find it useful to track coal consumption and cleanings.

They tell you how many hours something has run.
Anyone who feels they have a need to know how much something runs.
Pick one out amazon has them, you mount it wherever you think is appropriate and wire it parallel to whatever you want to keep track of.

You could use it to know when to do maintenance, or as rob does to figure your fuel consumption.

I personally don't think its needed but, some people don't think a tachometer is needed on a car.

I rarely look at mine any more. :oops:

When I first put the boiler in it was useful to see how it behaved with different feed rates, etc...now I just leave it alone and take out the ashes.

Here's a 110 vac-250 vac model...110 volt hour meter

So many other ones are for DC and less than 40 volt.

Interesting. I'd find them more useful if it recorded when it ran as well. That would let you know when the T-Stat kicked on versus regular idle fires.

For a very cheap alternative, pick up a pedometer at the Dollar Store. I wired it to a middle mouse button from a sacrificed mouse then attached it to the stove with a magnet, some Erector Set parts and a rubber band. Each time the stoker rotates, it advances by one. Lets me adjust my timers to keep the T-stat from coming on so much.

Sa-weet! Not familiar with the Harmon: so every rotation of the worm/gearshaft hits the mouse button which is wired to the pedometer and electrically 'clicks' it?

I was imagining the pedometer being on a crank-rod of some type, whose motion was be enough to make the pedometer work in its normal fashion - and was wondering what the mouse button was for. :-)

You could just get one of those little clicker-things that ushers used to have to count people and have the arm click that instead of a mouse button and be battery-free...

Nice speaker magnet. :-)

That's exactly how it works. I thought of using a baler counter (which is essentially like an usher-person-counter) but another member of the forum used a pedometer so I "borrowed" the idea. I also couldn't quite figure out how to mount a baler counter. The pedometer that I'm using is now three years old and still going strong. Yay, Dollar Tree!

The nice thing about this is I can tell if my stove runs just off the timers - which is what I want - or if the T-stat kicked on. I can also tell how hard the stove ran and if I'm approaching its total limit. For instance, if the stove ran flat-out, constantly fed, for 24 hours, on a 5 RPM feed motor, then its total potential is 5*60*24= 7,200 strokes per day. During the cold snap this week, the highest reading for 24 hours was about 3,300. Therefore, even with an average temperature of 1*, the stove ran at less than half its total potential. I realize that that's not totally accurate because of diminishing returns, but it's not too far off. I do know that it was 74* in the house all day on Tuesday.

It's all just more data for me to play with.

Understand the mouse side of this...now how 's the pedometer side set up?

I opened the pedo and found that there's a little weight on a spring inside that bounces and closes the circuit each time you take a step. I pulled the weight and the spring out, then soldered wires from the two terminals and ran them to the mouse button. Each time the cam on the stoker feed hits the mouse button, it advances the pedometer by one click.

Here's the original post by syncmaster that gave me the idea:

Yeah, more data is always cool - as long as its accurate data. ;-)

pedometers usually work with a swinging arm or ball in a arc-shaped track with a weak spring to keep it from just bouncing around and when you run/jog/walk, your body's motion is transmitted to the pedometer, overcomes the spring's pressure and the arm or ball goes from one end to the other and makes a contact, completing the circuit and marking a "stride". You then figure out your running/jogging/walking stride length and you know how far you've gone - roughly.

for this application, I would guess Horace hard-wired he two wires coming off the mouse button to the pedo's switch and voila...
