In this work a psychrometric model was developed in order to estimate the water and tar vapors that can condense in the syngas filtration stage of a commercial micro-scale gasifier: The Power Pallet 30 from All Power Labs. Starting from the gravimetric tar concentration analysis performed on the PP30 in previous works, the model was able to estimate that in the first 1.5 hrs of operation, more than 5 g of class 4 and 5 of tars condensate in the pipeline. The model applied to a real temperature profile of the gasification facility suggested a minimum operating temperature of the gas line of 42°C to avoid the water condensation. Instead, to significantly reduce the condensation of light tars, the minimum working temperature resulted in 70°C.
