A low emission hot water or steam supplying system (2.5 t/h) which consisted of a multi-fuel boiler and a plasma-chemical hybrid NO_x removal was demonstrated Bio-oils or waste oil with city gas or heavy oil (A type) could be fired satisfactorily maintaining a stable NO_x removal efficiency of more than 80%. Furthermore, a simultaneous removal of NO_x and SO_x was tested using mixed heavy oil (A and B type, sulfur: 0.55%) and a very high SO_x removal efficiency, more than 97% was obtained. This low-emission boiler system can be applied for the industry.
