Master's thesis investigated 3 boiler plant burning biofuel. The aim - to explore biofuel-fired boiler particulate emissions, introduce the world's most widely used means of reducing particulate emissions and investigate dispersion of solid particles on the basis of the composition of the measured 3rd in the target boiler plant, check particulate capture devices (multicyclones) are correctly selected and compare their theoretical clean degree with a measured. It is also expected to review the Directive 2010/75 / EU, which will come into force from January 1, 2016 date, the requirements of particulate emissions. Research work reveals particulate emissions from biofuels plants. Measure the particle dispersion composition and conducted verification battery cyclones calculations. The dependence of the degree of cleaning the boiler load changes, and the calculations of the change in certain groups capture the degree of decline in the speed of battery cyclones. After the calculations showed that multicyclones are selected correctly on the basis of economic and theoretical calculations. The calculated theoretical particle capture degree does not differ much from multicyclones producers claimed capture degree, but differs in a number of different measured from the boiler plant. On the basis of the new directive does not meet multicyclones cleaning from particulate matter requirements, recommendations are given for existing biomass boiler owners. |
