The prevailing technologies for boiler flue gas desulphurisation and denitrification are selective. The combined impact on the reduction of overall emissions of biofuel reciprocating grate boilers has not been sufficiently studied. This dissertation is intended to determine the combined effects of primary and secondary measures on nitrogen and sulfur emissions. Experimental studies were carried out in industrial boilers (4 – 12 MW) and research stands (20 kW) of similar design and operating conditions, burning wood and waste of agricultural, industrial and animal origin. Selective non-catalytic reagents (NH3, (NH2)2CO), solid reagent (CaO), flue gas recirculation, excess air and combination of these measures on flue gas NO2, N2O, NH3, HCN, SO2, SO3 and H2S emissions were determined. Flue gas recirculation and insufficient excess air have been found to reduce NO, NO2, NH3, SO3 and H2S emissions but increase SO2, HCN and N2O emissions. These methods must therefore be combined with additional desulphurisation measures. Experimental measurements also showed that selective non-catalytic reagent ((NH2)2CO) reduces not only NO, NO2, but also SO2 and H2S concentrations in biofuel combustion products. The dissertation presents a methodology for the calculation of NOx and SO2 concentrations in flue gas based on the results of experimental research, which allows for the optimal selection of emission reduction measures.
at 10:00 (EET) on November 10 the FAIRsFAIR Roadshow will virtually visit Lithuania to offer a FAIR programme, ranging from practical tools to FAIR-supporting projects. The event is open to researchers, data support staff, data stewards, and data policy makers and it is organised in collaboration with Kaunas University of Technology, OpenAIRE National Open Access Desk (NOAD) and the Open Science Communities.
The event will be held in English.

Dissertation title: Investigation of interfacial shear in condensing steam-water flow through a horizontal channel
Doctoral Thesis was prepared externally.
Science area, field of science: Technological Sciences, Energetics and Power Engineering – 06T
Defense of the dissertation: 2018-10-23, 14:00, Kaunas University of Technology (Rectorate Hall – 402 aud.), K.Donelaičio g. 73, Kaunas, Lithuania.

Dissertation Defense Board of Energetics and Power Engineering Science Field:
The doctoral dissertation is available on the internet and at the libraries of Kaunas University of Technology (K. Donelaičio St. 20, Kaunas) and Lithuanian Energy Institute (Breslaujos g. 3, Kaunas).
Not many experimental studies have been conducted in the two-phase stratified flow with condensation, and they are still in great demand for better understanding of the momentum and shear transfer between two phases and its influence to the turbulence.
In this work was determined the effect of condensation on the interfacial shear in the steam (4–8 m/s) and water (0–0.028 m/s) co-current flow in the horizontal rectangular channel with a length of 1.2 m, a height of 0.1 m and a width of 0.02 m. The established interfacial shear correlation can be used to improve numerical models of stratified condensing two-phase flow.
During the research it was contributed in the development of new Shear number Sn, and it was performed verification, based on mine and other authors’ experiments in two-phase flows. The design of systems and devices in which liquid and gas are flowing with great differences in velocity, it is necessary to know the flow regime, because the turbulence has a significant influence on the heat transfer. The new Shear number more accurately predicts the turbulence in liquid than Re, therefore Sn can be used in the field of thermal physics by analysing and designing two-phase non-condensing and most importantly condensing two-phase flows, such as heat exchangers, steam-water systems in industrial technological plants and their supply lines.
