Raw material should be filtered before grinding to remove materials such as stones or metal fragments [9]. Many pellet plants are equipped with systems separating biomass from inert materials such as stones and soil, or magnetic separators for metal impurity Figure 1: Pellets made from different types of residual biomass under different

Abstract. This handbook explains how biomass can be converted to a gas in a downdraft gasifier and gives details for designing, testing, operating, and manufacturing gasifiers and gasifier systems, primarily for shaft power generation up to 200 kW. It is intended to help convert gasification from a practical art into a field of engineered design.

Case I Preheating The furnace is used only for preheating. The material is heated up to 100 (C and there is loss of moisture from 10% in feed to 8% in the product. Heat required in preheater = Q2= F1# 0.37 (100 - 30) + X2# 560 [0.37 is the specific heat of biomass with 10% moisture] or, Q2= 25.9 F1+ 560 X2.
