【 摘 要 】

To reduce the production costs for heat used in drying fruit plants was studied using of local biomass from tree branch pruning. The average annual get 3 t / ha biomass whit energy potential of 37 GJ/ha at a cost of up to 60 €/t. biomass at 10 - 50 mm chopped and dried below 20% can be gasefied with TLUD process characterized by high energy conversion efficiency, stability and safety in operation, emissions of CO and PM very low. TLUD process produces on average and 15% biochar that can be used as fuel or as agricultural amendment to increase fertility and for atmospheric carbon sequestration. There have been experiments simulated by model of USCMER 30/60MGB dryer equipped with two thermal modules TLUD FORTE-40 for apple slices drying heat of the apple prinings. Biomass used and biochar resulting chemical and energy were defined as micro-gasification process TLUD. That can dry 205 kg of apple slices in 6 hours with 74 kg of dry biomass to 10% of that remains and 12.2 kg biochar, biochar with or without 52 kg biomass, which costs € 8.55 or € 5.97, ie 4.3 or 6.1 times cheaper than diesel. On dry ton of sliced apple it can produce 59.6 kg biochar with soil seize -174.8 kg. CO2.
