maybe you should look again, because that isn't a fair assessment of what I linked.
Permaculture can be relatively simple, but ecological engineering is a highly complex interaction of biological processes with a specific waste stream to address

those are world renowned biologists and pioneers in ecological engineering

just one example
Noorder Dierenpark Zoo - Emmen, Netherlands
host to 1,500,000 visitors annually. A Living Machine system at the zoo treats 220,000 gallons per day of wastewater generated by visitors and the maintenance of the housed animals. Treated wastewater is reused on-site for toilet flushing and other non-potable uses, including animal basins. As a result of the water reuse an 84% reduction in water consumption at the zoo has been realized.

anyone that has difficulties with information density is of course welcome to skip the links

this is science not religion, and such systems can be designed to treat specific waste streams, including industrial pollutants like hydrocarbons, cadmium, chromium, nickel, lead, ect.
which of course leads us right back to being "thread" relevant

ps methane is another typical by product of such living machines (from the anaerobic reactor)
and that can be put to a more direct use

wait...I thought this was about forge flues, not ecology... I'm confused! <sob>
I've only worked with hoods, it seemed that once the pipe got hot, it just sucked all the smoke and ahot air and sparks upwards and away. Straight pipe right up.

BioGlass

A typical, modern glass studio consumes 2- 6 million BTU of gas per day, for which prices have tripled since 2001, resulting in numerous closures of glass studios worldwide. Thousands of years of heritage and tradition are being extinguished. Costs of operating a glass studio combined with the loss of waste heat from the furnace make this an opportunity to collaborate efforts, to save fossil fuels, and provide community-based heating.

blacksmiths are different how? you can look at one little part of a problem or you can look at a bigger picture of a process, and entertain alternative solutions that may have something new to offer.

Chimneys are pretty well covered ground for the last several centuries, steel, refractory, stone, ceramics
most of the energy goes straight up and is gone. Simple certainly works, its easy to implement, its rarely the optimal solution, and in this case isnt horribly energy efficient, if it was possible to run a power hammer off the fuel your already burning, is it worth investigating? discussing?

Dave, this is an old post from the archive but may be of some use to you.

Chimney size and height

[Dave M]

Wow. Thanks for all of the help. Do to our fire codes I will have to have 2 chimneys, 1 for wood stove & 1 for coal forge oh well. For the propane forge, welder and plasma cutter I will use a direct vent fan inducted hood. Hofi's system looks so straight forward that I will use that design. Don't know if I can come up with the extra money for the stainless but I am going to price it out because it would be a one time purchase. As always you are all just a vast wealth of knowledge, and save me time and again from reinventing the wheel so to speak. THANKS
