Ash removal

We provide complete systems for ash cooling and removal from furnace and transport to storage vessel for power units with fluidized bed combustion. In such boilers dry ash removal systems are used and they are equipped with a sifter and a crusher.

Dry ash removal system is a high-tech solution nowadays replacing traditional method of hydro-ash-removal. It has many advantages which make more and more power consortiums decide to implement it in their plants. This method limits the need to use water in the process of ash cooling and handling (water is not dirtied), it makes it possible to reduce CO2 emissions and significantly reduces system production and maintenance costs. These systems are slowly becoming standard in countries like Germany or the Netherlands, however they are not so much common in Poland yet. 

Environment protection has lately became the main aim for many power plants in the world. Nowadays all efforts are focused on emission reduction (CO2, NOx, SOx, ashes, etc.) and to enhance ash, which had been treated as wastes several years ago. 

Moreover, international standards, which regulate the use of ash as component of cement or concrete, has changed lately. Ash is not wastes anymore, but may be used as a by-product provided that limits established in relevant standards are met.
