Question for you engineers. Mable runs at abt 100 RPMs (variable) at 160 PSI average. 12 inch bore at 38 inch stroke, Ten foot Flywheel at abt ten tons. 160 HP. If a generator was hooked to it by belt, and the drive pulley for the generator was 36 inch or 48 inch, how big (KW) a generator would that engine be able to run?

Probably 60 if you are lucky.

Nice pinterest page. Steam engines and Steamy novels.

The classic answer to your question would be 42, of course, but that may be wrong.

The day you figure it all out! LOL!

BTW. The RPM on the saw arbor was 540. I can NOT remember the dia of the pulley.

That engine ran two sawmills. The bolt mill upstairs -4,6, and 8 ft saw bolts-logs, and the big mill downstairs-10 foot to 16 foot logs.

“how big (KW) a generator would that engine be able to run? “151.236798 hp

altitude would be a big factor ... engine would be derated the higher you are ...

1 horsepower = 746 watts. Figure about 90% efficiency at best so figure about 100 kilowatts.

1 horsepower is 745.7 watts. 160 horsepower is 119.3 kW.

That's your upper limit.

At best. Probably more like 75 kw.

160 HP = 119 kW.

Call it 80 to 100 kW in the real world to account for any number of losses.

Then I told you ‘bout our kid, now he’s married to Mabel.

Well..at least I am getting answers.

I cried the day the mill burned down. Its all there yet and a new building was built around it so it has been under cover most of the time.

I wish I was rich, I’d get machinists in there to recondition it.

It was my dads mill and was built in 1938. It ran two shifts for the duration of the war sawing bolts and crating lumber for the war effort. It ran till about 1958 when Pop had health problems and had to shut the operation down. My brother started it back up around 1969 and ran it till 1985 when the mill caught fire and burned down.

I fired that dam boiler for many a hour and we all loved that engine. Oh. she’d throw a fit once in a while, but its a female thing I guess.

Perhaps some retired or semiretired FReeper engineer would do it as a labor of love?

You can run a 1000kw generator ....

at reduced load.

To: crz; null and void

I agree with null and void 80 to 100kW is a reasonable expectation. Something to keep in mind is that if you are running a highly inductive load the number will be at the lower end of that range. Inductive loads are anything with a coil of wire in them, transformers, motors, old fashioned crt’s etc... If you are running a mostly resistive load, lighting and such you will get more power. Also, the cooler the generator stays the more power it can deliver. The limiting factors in most generators is the heat caused by internal I squared r losses.

In 1938 they had virtually no electricity for lights there.

So Pop had one guy who was a hell of a scrounger and the guy got a generator from a truck and hooked it up to get lights in the mill. The old timers would talk about how poor the lighting was. But thats the way it was then.

We had a radio in the boiler room and that GD engine would keep time to Johnny Cashes Burning Ring of Fire. Believe it or not. But, like I said, the governor could be adjusted to speed it up or slow it down.

I worked at century electric during the early 80’s we built generators for cat who would mate them with a diesel to provide power on oil platforms or ships. The generators typically spin at 1800 rpm. some can be have the winding modified lower rpm.you would have to have your pulley ratio correct. sounds like you have plenty of horsepower and mass to start. It’s about 1 HP to KW as a ratio of engine to generator. on smaller generators ( < 250kw) the ratio tends to be about 1/2 hp to KW.. you probably could run a 100 KW generator safely. This site lists average home use per state, and remember that there are 720 hours in the average month so you would generate 72,000 kwh per month, assuming constant running.
