Assessment of protective properties of rubber lining in absorbers of flue gas desulphurization systems.
PublicationResults of research on degradation of rubber lining which is the main protection of absorbers in flue gas desulphurization (FGD) systems were presented. The power plant where the system operated is lignite-fired. Owing to measurements using electrochemical impedance spectroscopy and gravimetric determination of water content in the lining, the areas of the system which are most exposed to degradation were shown. The results obtained...

OPTIMALIZATION OF SORBENT FEEDING IN THE DRY METHOD OF FLUE GAS DESULFURIZATION
PublicationThe swiftly developing sea transport contributes to a considerable increase of fuel usage in the international shipping, which results in the escalation of toxic compounds emitted into the atmosphere. It is followed by the constantly heightened requirements limiting those emissions. In the case of sulfur oxide emission, inside of SECA (Sulfur Emission Control Area), the maximum content of sulfur in the shipping fuels used on the...

Degradation of protective coatings in steel chimneys of flue gas desulfurisation system
PublicationThis paper presents problems associated with corrosion of steel stacks and changes in philosophy of corrosion protection when implemented into flue gas desulphurization systems. In-situ tests were taken by means of electrochemical impedance spectroscopy at the stack which discharges flue gas before wet lime/limestone desulphurization. A very quick electrolyte absorption by the spherical infill vinylester coating was found using...

Flue gas treatment for SO2 removal with air-sparged hydrocyclone technology
PublicationWyniki badań dowodzą, że reaktor cyklonowy jest wysokosprawnym absorberem. Absorber cyklonowy pozwala na osiągnięcie stopnia redukcji 97% dla samej wody i zawartości dwutlenku siarki w fazie gazowej 5 mg/dm3. Dwutlenek siarki był usuwany również w wodnym rozworze alkaicznym (0.01 mol NaOH/dm3).

Flue gas treatment for SO2 removal with air-sparged hydrocyclone technology
PublicationOpisano wstępne wyniki badań laboratoryjnych usuwania SO2 z mieszaniny gazów z zastosowaniem reaktora cyklonowego (ASH). Do absorpcji stosowano wodę wodociągową oraz roztwór alkaliów. Zbadano wpływ natężenia przepływu gazu, natężenia przepływu wody oraz długość elementów ASH. Stwierdzono, że efektywność absorpcji SO2 z powietrza stosując technologię ASH jest porównywalna z efektywnością metod konwencjonalnych.

Research on flue gas flow measurement and modelling in the moving grate biomass boiler
PublicationThe aim of this research was to determine the nature of gas flow in a grate boiler model by the method of Particle Image Velocimetry (PIV) and CFD. The paper presents the comparison of the PIV results with numerical simulations made in the environment of ANSYS Fluent. The main goal of the experiment was to describe the phenomena occurring on the grate. Methodology of modelling solid fuel combustion on the moving grate was proposed...
