Biomass Handling

8.1 INTRODUCTION Liquids and gases are relatively easy to handle because they continuously deform under shear stress—they easily take the shape of any vessel they are kept in and flow easily under gravity if they are heavier than air. For these reasons, storage, handling, and feeding of gases or liquids do not generally pose a major problem. On the other […]

Glycerol Synthesis

Biodiesel from fat or oil produces a large amount (about 10%) of glycerol (HOCH2CH[OH]CH2OH) as a by-product. Large-scale commercial production of biodiesel can therefore bring a huge amount of glycerol into the market. For example, for every kg of biodiesel, 0.1 kg of glycerol is produced (86% FAME, 9% glycerol, 4% alcohol, and 1% fertilizer) (www. biodiesel. org). If produced […]

Feeder Types

The six main feeder types for biomass are: (1) gravity chute, (2) screw con­veyor, (3) pneumatic injection, (4) rotary spreader, (5) moving-hole feeder, and (6) belt feeder. These are broadly classified as traction, nontraction, and others as shown in Figure 8.16. In the traction type, there is linear motion of the surface carrying the fuel, as with a belt feeder […]
