Bought myself a Christmas present:



This is something that has been on my list for years. I have done quite a bit of experimenting with wok burners, most of it unsatisfactory, and have come to the conclusion that there is not much in the way of good substitutes for restaurant wok ranges.

The second-best thing I'd found was a heavy cast iron wok, round on the inside but with a small flat area on the bottom so it can stand by itself on a regular range. Heat that sucker up for 15 minutes and you can do a quick stir fry with about a pound of food. But once its heat is spent, you have to begin the cycle again, and wait another ten minutes or so for it to get ready. And cleaning it when it's hot is a bear.

This range is 125,000 BTU, in contrast to a regular restaurant range burner, which comes in at 35,000. (A quality residential range is only about 17,000 BTU.) There are other, less expensive ways to get that much flame, and I've got some outdoor burners that reach that level, but you end up toasting yourself before too long. This unit only lets the flame out the back, so the cook remains reasonably comforable. But you do have to be careful about lifting the wok while the flame is on, otherwise it's a great way to lose all your hard-won knuckle hairs.

The burners consist of 18 jets with a peculiar design, which you can see in more detail here, but this is what they look like in operation:



Firing it up is a little scary. Even with the stainless backboard and such, I spent a good bit of time making sure it wasn't roasting anything in its vicinity. The vent hood keeps up with it pretty well, and the rush of air coming up around it helps keep the surroundings cool. The oil baffles in the hood get a bit warm but not excessively so. I could imagine installing one of these outdoors, but it definitely isn't a residential device.

The main problem I'm having is soot, of which there is quite a bit. This unit is designed for propane but the flame is still mostly yellow. I don't think it's affecting the food but it makes things a little messy at clean-up time.

The good news? It makes things taste Chinese! I don't know quite how to describe it, but proper stir fries have a sultry, smoky-dark-alley aroma to them that comes about in part from extraordinarily high heat. Getting the right level of char is an art unto itself. It's going to be a while before I'm totally confident with this thing but my initial test - pork chow mein - was delicious. So I think we're going to have a Chinese banquet in the near future!

Btu per what?

It is really btu/hr but it's become conventional to just use "btu" when talking about appliances.

Over 7 times the heat of a normal residential burner? Wow!

As to the soot ... that usually indicates a burner running too rich. I have no idea how you adjust something like that, though.

Well, there is no traditional venturi or anything, just those strange burner nozzles with nothing adjustable about them. So I suspect I'm just going to have to live with it.

I am a short guy but this looks kind of low even for me...

It is kind of low, but it's easier to do vigorous stir frying at waist level than at stovetop level. I have considered raising it but it works fine like this, particularly with my bad right shoulder!

And did I mention how much I like short? Oh yeah I did! ;-)

Hmmm ... Wonder if the propane orifice is designed right? From the color, looks like it's burning up alot of propane.

The flame is yellow no matter how high or low I turn the valve. The regulator is adjustable, but is there any reason adjusting the regulator would be different from just turning it down?

Unlike many stoves there is no air intake regulator.

Impressive!

Is propane only or natural gas/propane depending on the insert?
If gas/propane double check that it has the proper insert.

I had originally ordered a natural gas unit with a propane conversion kit, but it turned out that the kit was very complicated and expensive, so I returned it and got one that's already configured for LP. Says so on the back, albeit in magic marker!

I suppose that there might have been some error, and that it's not configured right, but how to tell?

Basically you tell by the color. If it's yellow, it the orifice is wrong. I'm not an engineer, but once I was working on an industrial heater, and our local propane company had the conversion orifice for it.

The orifice is usually just a penny sized piece of metal with a hole drilled in it. The size of the hole determines how much gas comes out.

I got the general idea from the propane company that some units are just "guessed" as to the size, and some companies prefer to guess on the overconsumption side. If they went the other way their unit wouldn't work.

Is there any difference between using a smaller orifice and just turning the gas down at the control valve? The flame is equally yellow regardless of whether the valve is wide open or open just a little bit.

Hmm, I can't really answer that with authority, but the other answer would be to give it more air. Maybe calling the manufacturer?

Or maybe talking to the local propane company, not the person who answers the phone but they usually have a person who cleans and maintains the tanks before they go out for use. that would be the person to talk to.

Wow!! Soooooooo envious! Growing up in east Asia, it's the one thing I miss about the west — easy access to a good wok stove. They're totally impractical for my current living situation, but ohhhhhh how I covet them.

Have a hell of a lot of great food with it!
