Stoker fired boilers
Stoker fired boilers are the smallest units among hard coal fired boilers. They are mainly operated in local or industrial heat or heat and power generating plants. The construction of modern grates enables the effective combustion process combined with the release of significantly lower quantities of pollutants than in case of older stoker fired boilers. RAFAKO S.A. offers OR type steam boilers, WR type hot water boilers as well as modernisation of the existing stoker fired boilers.
