Design and Analysis of A Spiral Plate Heat Exchanger On Producer Gas [Biomass Gasification]

Producer Gas (PG) is derived from Biomass Gasification process. Producer gas is a mixture of gases which consists of hydrogen, carbon monoxide, methane, carbon dioxide, water vapour, nitrogen, tar and suspended particulate matter. For satisfactory IC engine operation, an acceptable particle content < 50 〖mg/Nm〗^3and tar content < 100 〖mg/Nm〗^3 is postulated. Tar available in vapor form is separated from Producer Gas by condensation. Hence cooling and cleaning of Producer Gas is an important step for the effective operation of IC engines. Design of spiral plate heat exchanger was created on the basis of heat duty and allowable pressure drop requirement. Geometric model of spiral plate heat exchanger is created by using CREO Parametric 2.0. ANSYS Workbench 16.2 is used for Numerical Analysis (CFD) of geometric model. It is estimated to simulate the model by varying the mass flow rates on both side and by increasing the thermal resistance to heat transfer.
