<p>A combined oven and fume incinerator having an enclosed housing (1). A combustion chamber (31) serving as a heat source and fume incinerator is connected by a heat recovery air duct (32) to various process zones (15-20) which in turn open into a cool air inlet passage (33) leading to the combustion chamber (31). A blower (35) is provided to circulate air through the housing (1), combustion chamber (31), heat recovery duct (32), process zones (15-20), cool air inlet passage (33) and back to the combustion chamber (31). The heat recovery duct (32) is in direct thermal contact with the cool air inlet passage (33). An exhaust fan (60) is located in the cool air inlet passage (33) at a point where there is the least pollution to exhaust a portion of the air in the passage to atmosphere. </p> |
