Furnace

The paddle fan is connected by ducting to a 0.3 m3-capacity cylindrical furnace. A flap valve is located in the duct to reduce the effect of any 'blowbacks' from the furnace during operation. The furnace casing, of overall dimensions 950 mm diameter by 1040 mm high, is fabricated from mild steel and has an insulated inner sleeve. The furnace chamber is lined with refractory cement to a depth of 100 mm for the wall and 60 mm for the floor. The removable furnace lid is constructed from heat-resistant ceramic boards, fixed onto an outer mild-steel sheet. The inlet and outlet ducting is manufactured from stainless steel for increased heat resistance.
