<p>A process for the treatment of poultry droppings and similar biomasses, characterised in the production of solid fuel through heating of the poultry- droppings under vacuum, in a current of steam at a temperature between 250 0C and 4800C. This process being achieved by the use of a plant consisting of a reactor (10), supplied under vacuum through chambers divided by valves, and in that the plant comprises a stirrer with blades, which causes the mixing and infeed of the material from the entry point towards the exit point at a variable speed, according to the nature of the product and its humidity, and that the flows of steam are injected as required on the entry side by a steam generator (11) and extracted near the discharge point with the volatised substances passing through a condenser (12) and then to the vacuum system (13) with a scrubbing effect on the incondensable products.</p> |
