All along the combustion process, some adjustments and upgrades can be made to maximize the amount of steam/energy produced by the waste and as a result, generate a higher profit for the plant.
Pay back of investment is often 6 month after completed commissioning.
A lower efficiency in the plant is often caused by:
- Mechanical wear on some parts of the furnace
- Residuals accumulating at the surface of the boiler, creating an isolation lining and having a double consequence: a lesser steam/energy production and an increased temperature in the boiler
- Ineffective secondary and primary air control causes wrong combustion distribution on the grate surface and low efficiency of the complete combustion system
- Operators having problems in controlling the waste feeding due to long time delays in the process
