The feasibility of a conical spouted bed combustor for the thermal catalytic exploitation of vineyard pruning waste, under different operating conditions has been analyzed. Stable-flow regimes of vine shoot beds with a Pd catalyst were determined over a wide range of combustion conditions. With the aim of improving the combustion yield, thermal exploitation of vine shoots was performed in batch mode, in a conical spouted bed combustor at temperatures ranging from 250 to 550 °C, with and without the Pd catalyst. The influence of the catalyst and inlet gas temperature on the flue gas concentration was analyzed. The experimental vine shoot combustion yield with the Pd catalyst at different inlet gas temperatures were compared with those obtained without the catalyst. The high experimental combustion efficiency calculated from the flue gases concentrations demonstrates the favorable performance of the conical spouted bed combustor for the catalytic combustion of vine shoots.

分析了锥形喷头燃烧室在不同操作条件下热催化利用葡萄园修剪废物的可行性。在较宽的燃烧条件下，测定了带有Pd催化剂的藤蔓芽床的稳定流态。为了提高燃烧效率，在锥形喷淋床燃烧器中，在有和没有Pd催化剂的情况下，在250至550°C的温度范围内，以分批方式对藤条进行热利用。分析了催化剂和进气温度对烟气浓度的影响。将使用Pd催化剂在不同进气温度下的实验藤蔓燃烧产量与不使用该催化剂获得的藤蔓燃烧产量进行了比较。
