What is charcoal? Charcoal is the solid residue remaining when wood is "carbonised" or "pyrolysed" under controlled conditions in a closed space such as a charcoal kiln. Control is exercised over the entry of air during the pyrolysis or carbonisation process so that the wood does not merely burn away to ashes, as in a conventional fire, b

The distillation of wood Charcoal is a useful by-product of wood obtained by the process of carbonization. Other valuable products can be obtained by treating wood in different ways. Destructive distillation (also known as pyrolysis or wood distillation) is similar to carbonization except that the wood is heated in a closed container and the gases and liquids given off are collected. Some of the gases can then be condensed to provide a range of useful chemicals; those that do not condense can be used as a gaseous fuel f

Output A few kW for 4 to 8 hours with an air door opening 20 to 30 mm. The burn rate increases near the end of the sawdust charge, as the burning core expands out to reach the inner container walls. Up to 7 kW can be produced, but at this output the case glows red-hot, so inflammables must be kept well away, and the fuel charge does not last long. Figure 2: Removable inner bin with hole through to air chamber below (H Bland) [top] [end]Operation The heater comprises two concentric bins. The removable inner bin has a hole through the bottom to the air chamber below. This allows hot gases to be drawn upwards through the hole to where combustion occurs. The hot gases are then drawn downwards between the inner and outer walls of the heating stove, providing good heat exchange to the room as they pass between the two chambers before passing out of the room through a flue (Figures 1 & 2). [top] [end]Fuel range Sawdust is best. Shavings or chip-pings will work provided they do not collapse down the airway. They work better mixed with sawdust, but have the effect of making it burn faster and hotter.

"New process"According to our inventive process the advantages of alkaline transesterification of triglycerides and esterification and transesterification of triglycerides with homogenous catalyst were joined together. This is reached by carrying out conversion of oils into one or maybe two steps. (See enclosed scheme.)
