his response to a question on ebay
"We have sold many Steam Cleaners to American,
Mexico, Nicarragua, Australia, Cyprus, Oman.
It is a well proven good tool for cleaning job and
its price is 1/3 of competitors. It is a powerful
tool to clean greasy in milk powder plant,
restaurant, machineshop. It must be able to clean
coal dust effectively.
The stove is indeed a patent. We are looking for
American manufacturers to co-develop it to a
commercial type stove suitable for American
market.
Pardon my poor English.
You seem to be in the area of coal. You should
know its potential value. Even my prototype is
MUCH MUCH MUCH better than handfired stove.
You can fill the stove once a day. It burns coal
very cleanly by observing the flue. Its basic
function is same as a modern stoker, but more
simple and cheaper and more reliable. It is also
very easy to upgrade to computer controlled modern
smart stove. When electrical supply is down, it
can still work."
confusing...
