摘要

Datorita densitaTii scazute, arderea biomasei de tip deseu lemnos ridica probleme deosebite legate de alimentare si de incarcarea termica a focarului. Se prezinta date experimentale privind eficienTa arderii si nivelul emisiilor NOx obTinute pe un instalaTie cu o putere de 1MW. S-au studiat doua tehnologii de ardere diferite prin modul de alimentare a combustibilului: in echicurent, respectiv in contracurent cu aerul de ardere. 'Pentru regimul termic s-a folosit o camera cu infrarosu. Rezultatele s-au dovedit suficiente pentru desprinderea unor concluzii teoretice si practice privind dinamica emisiilor de NOx. Combustion of biomass with low density like wood resufues, rises special teclinical problems related to the difficulties to supply the fuel, therefore some dijficulties to achieve an appropriate thermalloading of the furnace volume. The article presents data concerning burning efficiency and Nox pollutants level, provided by experiments on a pilot furnace with 1MWt medium power. Two tecUnologies for supplying the solid fuel are testedthere: downdraft and updraft with combustion air. Tor accuracy, the temperatures in the furnace have been measured with a IRcamera.
