welded at the top with the water seal. The fuel chamber has a flange attached at itsbottom; this is used for connecting the fuel chamber with the reaction chamber.Primary air inlet: The primary air inlet (Figure 2.14) is made of 2 mm thick mild steelsheet, and is attached on one side of the reaction chamber. It is provided with abutterfly valve, which can be used to control the gasification rate inside the reactionchamber by controlling the primary air flow.1"x1"x1/8"L angle frame2517.5Bolt holes5/16" dia.2124.513 12Dimensions are in cm unless otherwise specifiedFigure 2.14: Isometric view of primary air inlet manifoldGas Burner: The gas burner has two parts: the support at the bottom or gas burnerbase (Figure 2.15) and the burner pipe (Figure 2.16) which is fitted over the base.16x16 squareBurner mounting ring,15Ø outer1"x1"x1/8"L angle frame21129Bolt holes,5/16" dia.817.524Dimensions are in cm unless otherwise specifiedFigure 2.15: Isometric view of gas burner base14
The burner pipe has forty-four holes of diameter 10 mm drilled into it in four rows,through which secondary air flows in, for combustion of the producer gas. To reduceheat losses, the surfaces above and below the secondary air holes are insulated withrockwool and clad with 1 mm thick GI sheet.1GI sheetcladdingRockwool insulation,2.5 thickSecondary airholes, 1Ø4131522291015ØDimensions are in cm unless otherwise specifiedFigure 2.16: Sectional view of the gas burnerThe gas burner base is insulated with a 2 cm layer of refractory cement (Castable 13)on its entire inner surface.
