Mixed fuel fired boilers (oil, gas, coal)
The construction of this boilers is similar to those fired solely with pulverised fuel, oil or gas. The main difference lies in furnace system and mainly in burners. This solution is generally applied by the customers for whom such combination of fuels is easily available. One of RAFAKO's most important projects within this group of boilers is rehabilitation of three OOG-320 boilers at PKN ORLEN company in Płock.
