Sep 02, 2015 · I have a Buderus 02.40-6 (rated at 140k on coal/gas/oil and 125k on wood) in my garage. With those water-cooled grates it is efficient for wood but a PITA for coal. Quality, heavy duty unit with cast iron watertube design but limited size firebox. To me it looks like a good basement wood burner for a small- to medium-sized house.

Feb 23, 2016 · How Do Waste Heat Recovery Boilers Work? Typically, this system consists of a standard water tube boiler that allows the hot exhaust gases from gas turbine incinerators to move over multiple parallel tubes filled with water. The water vaporizes in the tubes, collects in a steam drum and is utilized as heating or processed steam.

By controlling the inflow of the high secondary and tertiary air flows to the recovery boiler, the residual oxygen was reduced from 3.0 to 2.3 %, with a standard deviation reduction from 0.32 to 0.14 %, i.e. a 56 % reduction. Overall, this resulted in an increase of 2.7% high pressure steam generation on the recovery boiler.
