The definition of a combined power plant based on the fact that the different types of thermal energy requirement in multiple phases of production and it is obtained from a single fuel source. Combined power plants that we design and built for chipboard and MDF plants are in this category.
As an example, thermal energy input needed at different stages of production in the MDF production;
- Hot gas: As for drying fiber in the dryer
- Thermal oil: As for to turn the cake into MDF board in the presses
- Steam: As for chip softening in the refiner section.
The hot air obtained in the combined power plant is sent directly to the dryer, and the obtained thermal oil is used both as a heat source in steam production and sent to production to feed the presses.
The need for hot gas and hot oil is produced as a result of direct combustion and the steam is obtained in the steam generator indirectly by using thermal oil.
In the combined power plant;
- Wood scraps,
- Chip,
- Intermediate products returned at various production stages,
- Saw dust,
- Sander dust,
- Fiber
- Agricultural and forest wastes
- Other production wastes are used as fuel.
Large pieces such as wood waste and chips are burned on the moving grate system, while small pieces such as sander dust and saw dust are burned in the dust combustion chamber.
