The ash accumulated in the ash pit is periodically removed by opening this door.The door is also used while igniting the stove, by introducing a flame torch frombelow the grate, which supports the fuel bed inside the reaction chamber.Fuel chamber: The fuel chamber (Figure 2.13) is made of 2 mm thick mild steel sheetand is located above the reaction chamber. Fuel from the fuel chamber flows into thereaction chamber by gravity. The chamber is designed to be conical in shape, toavoid ‘fuel bridging’ inside the chamber, and to facilitate easy flow of fuel. The topend of the chamber has a water seal and a cup-type lid for easy loading of fuel; thewater seal also prevents gas leakage from the joint during operation.12.5Ø18Ø3 2.5445550114ØLid1528Bolt holes, 5/16" dia.9.528x28 square,3mm thick9.5Dimensions are in cm unless otherwise specifiedFigure 2.13: Fuel chamberTo protect the stove operator from accidental burns, and to reduce the heat lossesfurther, the outside of the fuel chamber is covered with a mild steel shell, which is13
