wood chip burner prototype B 10kW power system 3.MPG

wood chip boiler 30kW steam generator / home electric and thermal power generator system / over fuel test, ~200kW flame power with 4 foot flames shooting out of top of burner. Combustion is smoke free. Smoke generated is from spilled chips on top of burner during prototype test. Production units will use automatic chip auger and be completely smoke free and automatic computer controlled for up to 10kW electricity and heat generation using steam turbine and hydronic heating of home, business and or hot water.

Rocket stove has around 50 to 100 feet of 1/4 or 1/2" copper tubing depending on who built it. This is a different geometry, and has around 500 feet of 3/4" high pressure high temperature stainless tubing. It can output enough heat to take care of home heating load in 2 hours operation per day. And, it will drive 1000 psi superheated steam through a turbine to generate electricity.......things no Rocket stove can do. But of course, yes, both make heat using wood via monotube boilers.

looked like you had a chimney fire

[woodfirepower]

@firewoodguy2009 ......Yes, a chimney fire would look similar. Here, though, the flames originate from a large amount of wood chips thrown all at once into the burner. The volume of wood gas evolved is greater than can be burnt prior to exiting the top of the chimney, so the flames come right out the top. They die back down after a short period and can be kept indefinitely out the top if you wanted, just add plenty of chips.

So no, its not a chimney fire.

To accurately measure the heat the boiler is putting into the water, you can measure the water flow rate in gallons per minute or other units, then measure the inlet and outlet temperatures (for water in / water out), and compute the heat input as 1 btu/pound water per degree F. So for example, for 8 pounds of water in one minute with a 100 degree F temperature rise, you get 8 * 100 btu / minute. That is equal to 800 btu/minute, or, about 14 kilowatts. Steam's a bit more complicated.

Your numbers ....30KW and 200KW are "dreamland" numbers

NO WAY it's that high

[woodfirepower]

@kmcwhq

~15,000 BTU / pound * ( 7 pounds / hour) = 30 kW

I was running the fuel at around 5 pounds during the 2 minute video, so that's around

15,000 BTU / pound * (5 pounds / 2 minutes) = 660 kW...........

Also, I've produced a measured 45kW steam from the boiler running a small fraction of the heat in that video, and it isn't 100% efficient....so yes, 200kW is about what it was making during that video.

If you think I'm wrong, show me some numbers...rt

Wow

This looks like a modified rocket stove.So I guess I'm missing the point. So you can waste heat using your ideas. I thought the idea was to be able to construct something that burns efficient and doesn't waste.

He is right on the power output though it may not be exact it is right. And xoxo what does ohms law have to do with any of this? Ohms law is purely for electrical resistance.

[xoxoXoieoxox]

@woodfirepower ok in this sit. its not the numbers its the fact that ther are 2 many veriabls that u dont realy know like whats the humitity of the air ur blowing in and what i the effect. and remeber even omms law isnt 100% acurate math is good and all but nobody knows nature 4 shure =3-
