The furnace has boiler (2) with combustion chamber (3), and a walling (5) in which inlet opening (6) for combustible material and outlet opening (7) for discharge of exhaust gas from combustion chamber are formed. A combustion grate (9) receives and combusts combustible material by receiving combustion air from air channel (43), which is blown by blower (41). The air channel extends and circulates around the combustion chamber, so that supplied combustion air simultaneously serves as cooling air for cooling walling of boiler. |
