How the biomass heating system works
The KOZLUSAN biomass heating system produces few emissions and achieves a high level of heating
efficiency because of its unique design. The fully automated fuel delivery is ‘ poured from top ’ into an air
fed burn pot where the fuel is self ignited before the full modulation control system controls the burn for
minimum emissions with maximum heat output.
To understand how the KOZLUSAN heating system works, we need to look at the flow of air, fuel and gases
through the heating system and the transfer of heat from the superheated gases to the thermal transfer fluid.
We also need to understand some of the terminology used to describe the systems operation;
Air Flow through the Biomass heating system
1. Fuel is fed from the fuel store via an auger. The fuel is poured from the top into the cylindrical burn
pot to maintain a physical separation between the fuel store and the fuel feed. Heat from the burning
fire is force fed air from a variable speed fan. Various sensors measure temperature in the boiler (a
thermostat that works in water) a flue gas temperature sensor (probe in the chimney), outside
temperature sensor (the weather or room temperature) and a safety cut off temperature sensor to
protect against overheating (high limit stat).
2. As air flows through the firebox, its temperature rises to nearly 1000
º
C.
3. This superheated air rises upwards and then through a series of heat tubes where the heat is
transferred into the thermal fluid.
4. By the time the exhaust air reaches the flue, most of its thermal energy has been absorbed. The final
temperature of the escaping flue gas is less than 175
º
C.
