OptiCOM - Fluidized Bed Combustion System
A fluidized bed is an ideal method for the combustion of diverse and challenging solid fuels. Steenova's OptiCOM steam generator is an important step towards the perfection of combustion technology for solid, wet and muddy biogenic waste. For heat ballance reasons the bubbling bed combustion chamber is integrated in a high pressure steam generator.

Operational Areas
Unique feature of the OptiCOM combustion chamber (sand bed with a high heat-capacity), together with a well-directed designed freeboard and an adequate management of the air for combustion, provides OptiCOM the possibility of a wide range of operation.
One of the advantages of the OptiCOM fluidized bed combustion system is its vast combustion flexibility of multi fuels. The diagram shows the fuels which have been used until now and their calorific values. As the ash softening temperature decreases towards the right, there will be a greater risk of corrosion in the combustion chamber. OptiCOM technology is capable of burning fuels with low calorific value and with low levels of ash softening.
OptiCOM plants allow a wide spectrum of fuels; the operational characteristic can be adopted to the customers needs.
OptiCOM boilers fully comply with the emission standards of the European Union. The measured values are even undercut considerably.
