Complete equipment of the hot air heat exchanger is located in the standard ISO 40 ft container partly inside and partly on top of container, overall height to suite road transport.Furnace is design to suite type and moisture content of the fuel, it is suitable for wood waste such as bark, sawdust, shavings, clear fell waste and/or agricultural biomass.

For biomass fuel up to 5 mm in size (dry sawdust, shavings, sunflower husk, shredded straw) cyclonic combustion furnace is used, and bigger size fuel (bask, wood chip, corn cob, shredded corn and sunflower straw up to 50 mm conventional grates furnace is used.

Air for the turbine is heated by hot gas from biomass fuel combustion in the tubular heat exchanger design for high temperature (steel temperature up to 800 oC), in order to withstand temperature requirement the hottest part of the exchanger is made from material which is heat, corrosion and abrasion resistant. Selection of material and working condition for biomass fuel is important to avoid damage of the heating surface; it is suitable for all type of biomass (wood and agriculture biomass) which the melting point of the ash is above 950 oC. Removing the ash from the heating surface is fully automatic by air sool blower which allows continuous operation (8,000 hours per year). Ash and slug removing from module is full automatic.
