Re: Econo Stove Blower Problems

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.

And a MIG welder is designed for the extreme electrical noise an arc welder produces. You can be sure it was designed to protect the sensitive stuff.

Gerry, thanks for the info,if I wanted to oversize an inverter generator for a Hyfire 2 how many watts would you recommend. Thanks again, it's starting to make sense now

Thanks for the welcome.

Inverter generators will always be so marked. Heck they are the latest and greatest. (??? re greatest)

Sine wave inverter generators will be so marked. There are a very few "stepped approximation" units that are not clean sine waves. Just stay away from el-cheapo Chinese inverter units.

If a conventional unit says "brush less" you know it is an alternator. The reverse is usually but not always true. The biggest issue with brushes is the springs corroding over years with little usage.

At least it is simple to tell inverter units from conventional ones.

One more note - you used the word "years" and "4000". That pretty much indicates a conventional generator/alternator which tend to be clean and rugged.

Thank you, gerry_g . I was going to start another thread and re-post this info as I get time( now I guess I don't need to ) it is very informative .

I was afraid someone would ask something like this! I don't know all the specs involved to give an honest answer. Will you be tempted to plug something else in?

I've seen a lot of inverter generators as I have camped (we usually dry camp). Folks with 1000W units tend to fire their temper. Folks with 2000W units tend to be happy campers. Those with 2600+ watt units can keep their cool with the camper's AC. Heck, even pop ups have roof ACs these days.

Except for weight and size, I personally prefer brushless conventional units. They are a lot cheaper as well.

Another unrelated factor that sways alot of people to the more expensive units is noise. As price goes up, noise goes down in lock-step. Cheap = loud, Expensive = quiet.

These days -- at least in my neck of the woods -- that's all anyone cares about. That will play a huge factor in someones purchase if they live near me.

This is a question for gerry_g .... Let's assume we have an inverter type power source, one that produces the poorest non-sinewave output waveshape. Is it possible to design a passive filter that would clean up the spikes, waveform irregularities, etc? It seems to me such a filter would then allow motors to be successfully run from inverter sources. The filter that would dissipate all the higher than fundamental frequencies and not the motor. My limited understand of the details was that the motor was attempting to run at multiple speeds, speeds corresponding the the harmonic frequencies produced by the square or rectangular waveshape. Something the motor can't do. That energy was dissipated in the motor windings causing hum and heat. Is there more to it?

I've made several referenced to camping. Noise is a major issue there along with weight. Noise is a very interesting topic.

Many inverter generators are 2 stroke (oil mix with gas is the way to tell), many are 4 stroke. Both types claim to be low noise, however the two stroke versions produce a much higher pitch that can be very annoying even if measured as quieter.

Lower noise with an inverter generator is often because they are used at far below rated output and the engine throttle down. An advantage of inverter generators is they can slow down under light loads without affecting the frequency or voltage output. Conventional generators need to operate at constant speed to maintain frequency. They can regulate voltage independent of speed.

Conventional generators can be made just as quiet. The manufacturers just need spend a couple extra dollars on the muffler.

My conventional Yamaha 5200 Watt generator is FAR less annoying than almost any 2 stroke 1000 Watt inverter generator! Yamaha just put a decent muffler on it.

I always thought it was the other way around -- when the big 4 started changing all their dirtbikes to 4-strokes, we noticed more noise complaints because the deep sound of the 4-stroke penetrated everything .... where the more "tinny" sounding 2-stroke wouldn't be heard ... and definitely not felt .... with the windows shut.

My EF not only has a muffler fit for a small car, but it also has acoustical foam glued to each of the 4 panels which completely enclose the engine. If I remove just one panel, the sound increase is very noticable.

Any surges mentioned regarding generators are current surges and usually cause a distorted voltage waveform, "Surge protectors" are intended to prevent damage to severe voltage surges due to events such as lightning strikes. They simply absorb voltage spikes, do nothing related to noise or "unclean" power.

noticable.
Dirt bikes and many motor cycles often have almost no muffler. The "sound" is part of the "thrill". Lower frequencies are also harder to muffle. Perhaps some of the problem is distance. Higher frequencies are more easing attenuated by foliage and the like. When camping one is often pretty near the generator. I did qualify the statement with "can" since there are exceptions.

No, in a practical sense. Even passive power conditioners are designed to solve a specific problem for a specific type of load - see below.

You run into a real problem here. Most AC and all shaded pole speed reduced motors have "slip" - rotate slower than the supplied AC frequency. Motors also act as generators at whatever speed they are currently rotating and may reverse feed (yes, the supply may need to absorb power from the load if maintaining a sine wave is desired) Or the motor may present an surge load. Thus causes current surges at frequencies below nominal 60HZ. The source must have enough guts to absorb any such surges which are NOT a harmonic of the supply and a lower frequency than the supply's fundamental frequency! If your blower is running at 20% speed, you have to deal with a 12Hz component!

These are some of the reasons I often state you need a "stiff" supply (maybe over sized) and not to use light gauge long power cords.
