Figure A-8. Ceramic Diffusion/Dust Seal Assembly

These modified diffusion and vee deflector assemblies are available in standard, Figure A-8,and flame arrestor version, Figure A-9.

b.Ceramic Diffusion Assembly

The ceramic diffusion assembly, Figure A-10,is the traditional design for the probe. Used for over 25 years, the ceramic diffu- sion assembly provides a greater filter sur- face area for the probe.

c.Flame Arrestor Diffusion Assembly

Where a high concentration of unburned fuel is present in the exhaust gases, a flame arrestor diffusion assembly, Figure A-9and Figure A-11is recommended.

The flame arrestor diffusion assembly in- cludes a set of baffles between the cell and the stack gases. This keeps 1500°F (816°C) cell temperatures from igniting unburned fuel in the stack.
