[Stoves] Pyrolysis adaptation for tea factory

[Anand Karve]

Dear Pablo,
you may look up our web site WWW.samuchit.com for the video of a stove
which my daughter, Dr. Priyadarshini Karve, designed. It burns woody
biomas. The name of the stove is ELFD Sampada. ELFD stands for
"electricity-less forced draft'. The forced draft mechanism is actuated by
steam pressure and not by using  electrically driven fan or blower. Because
of the forced draft mechanism, the stove burns very cleanly. We are already
in the market with sizes ranging from household size to canteen size. You
may contact samuchit at samuchit.com if you want to know details. .
Yours
A.D.Karve
