Abstract:

The analytical review of the experimental research results of energy plants preparation, burning efficiency and the emissions of harmful substances into the air while burning these plants, is presented in this paper. After the experimental study, immature (1–2 year of growth) willow (Salix viminalis) stems chaff chopping quality were observed. In truth, use of the drum chopping equipment prepared chaff fractional composition, and there were defined and calculated immature willow stems chaff of theoretical length (from 11.8 till 61.3 mm). They were presented and compared with the experimental research results of the low power boiler efficiency and harmful emissions into the air while burning energy plants – immature willow, chopped by the drum chopper of Maral-125 combine. The test was carried out in the laboratory of the low power boiler, which is designed to burn wood, wood briquettes and large wood chaff. After determination of boiler efficiency and harmful substances (CO2, CO, NO, NOx) emissions into the environment while burning different lengths of willow chaff, it was concluded that the boiler developed about 66–86% of nominal boiler power, and pollution emissions concentration into the environment was lower when willow chaff of 49.2 mm length was burned.
