marine stoves

I am looking for a marine stove with 2 or 3 burners with high BTU's (over 6,000-10,000). I can't locate a reliable resource for Broadwater, which is all I have found as yet. Any suggestions?

Umm... it would seriously help if you said what fuel you wanted to use for the stove. Propane, kerosene, and diesel are probably the only choices for a stove with that high a BTU rating.

Actually, Alcohol would meet her needs. An Origo catalyzed alcohol stove puts out 7000 BTUs per burner. Most two burner propane stoves have a pair of 7,000 btu burners and most 3 and 4 burner propane stoves have a 10,000 to 11,000 big burner as well. Diesel usually have 8,000 to 10,000 btu burners.

The latest PS lists the Force 10 Propane Stove/Oven as their pick. "It has two 4,100-BTU front burners and one 8,200 BTU back burner." The other factor was that the door of the oven slides under the stove once it is open, so that the stove remains balanced on the gimbal.

I always thought that (in general) you would get a higher BTU rating from a propane stove than an alcohol stove. I imagine that with more surface area per burner, an alcohol stove will have a higher BTU rating, but Propane is still a hotter flame.

marine stoves

I'm looking for a propane stove. I have the force 10 with one 8,000 burner and 2 4,500 btu burners. I am looking for at least 2 8,000 - 10,000 BTU's.

Seaward makes one with two 7000 and one 10000. Just a cooktop, no oven. Maybe they make an oven model as well. Here's a link to it.

When you've brought your new stove
all shiny and bright,
And it hangs in your galley
and looks oh so right.

You'll have an old stove,
and wonder what should you do...
send me an e-mail...
I'll be glad to accept it from you.

When you think Christmas...
Think of me.... : )

Quote from Eherlihy
"I always thought that (in general) you would get a higher BTU rating from a propane stove than an alcohol stove. I imagine that with more surface area per burner, an alcohol stove will have a higher BTU rating, but Propane is still a hotter flame."

If an alcohol burner has a higher BTU output that burner is putting out more heat per unit of time, which is what effects the rate that a pot heats up.

But I want to comment on the quote above. While it is a true that a theoretical flame temperature of propane flame is hotter, the difference is tiny. In real life applications it is not necessarily the case. The heat of the flame is determined by the design of the burner and access to oxygen. With a proper blemd of oyxgen propane burns at temperature that is only 1% higher than Alcohol. (see table below) The brilliance of a catalized alcohol stove (like a Origo) is its high efficiency in getting heat out of alcohol while marine propane burners are not especially high efficiency.


In making the statement, I suspect that like many people Eherlihy is mistaking the heat capacity of propane per pound (propane produces nearly than twice heat per pound of alcohol or 10% more than diesel fuel) for the heat of the flame.

Respectfully,
Jeff

slightly off topic for sure.
I am a new member and a new owner of a sailboat which came with a two burner kerosene stove. My problem is when I pull out the pin for the stove to enable it to gimbal it does sit level. Do these things have an adjustment to enable them to sit level? And what magic to I have to perform to get it to sit normal.
thank you

David-

You'd probably be better off starting a new thread of your own, since this isn't really on-topic for this thread. Also, please read the post in my signature to help you get the most out of sailnet.

As for gimballing the stove and leveling it... why is there a problem if it does sit level??
