During the process of gasification of solid wood some tar and other condensates (acids) may accumulate in the fuel bin.
- Page 3 The MA hot-water boiler is intended for heating homes and other types of buildings. The boiler is designed exclusively to work on burning wood. Any dry wood such as chopped logs or wood chips with maximum length of 500 mm (MA 15 – 350 mm, MA 80 –...
- Page 4 3. Technical Description The boiler is designed to work on burning wood. The combustion process (which is based upon power generating gasification) is obtained by passing ambient air into the firebox (furnace) with the use of an exhaust fan. The boiler shell is made from steel plates as a welded assembly. It consists of a fuel feed hopper, which at its bottom part is equipped with a fireproof insulation brick that comprises a longitudinal opening (nozzle) for exhausting the combustion products.
- Page 5 The appropriate type of fuel is dry wood with max. 20percent moisture content. Logs should be with maximum length of 500 mm (MA 15 – 350 mm, MA 80 – 650 mm) and calorific value of 15 – 17 MJ.kg .
