Design And Fabrication Of Biomass Burner For Gas To Gas Heat Exchanger

A biomass burner integrated with gas to gas heat exchanger has been designed,
constructed and evaluated. The direct flue from the biomass combustion inside the
burner will flow into the dryer for the drying of biomass waste product. The burner is
designed to supply heated air to the existing dryer model for biomass waste drying and
food drying application. The burner use three types of biomass energy fuel which is
Empty Fruit Branches (EFB), wood chip and rice husk. The gas to gas heat exchanger
installation is important since the combustion of biomass hydrocarbon will be producing
poisonous gas and it is not suitable for food drying application. Gas heat exchanger will
use extended surfaces on both side of its cylinder pattern to increase the surface area and
also increased the heat exchanger efficiencies. Material selection for this design is
crucial because the unit must sustain service temperature around 300ºC. Stainless alloy
has been chosen as the material for the heat exchanger. The experimental result shows
that the output parameter obtained from the burner is within the required value. In
conclusion, the burner had been detailed design and fabricated and give the required
value needed for drying application.
