Water park modernization with the use of renewable energy sources

Załuska W., Tomaszewicz-Załuska D., Łach J

Polska Energetyka Słoneczna

2014

nr 1-4

18--25

The paper presents the modernization of the Water Park (WP) involving application of RES systems such as: (i) solar photovoltaics (PV) and solar collectors installations; (ii) heat recovery ventilation with heat pump; and (iii) recovery of low-temperature waste energy from WP sewage. Each system is a separate technological unit with an independent control system. For their full integration, a supervisory control and visualization sytem has been developed. The initial estimation of the energy performance before and after the modernization confirmed the WP energy efficiency increase and achievement of the anticipated economic and ecological effects.

Effects of ecological water park modernization

Załuska W., Tomaszewicz-Załuska D., Łach J

Polska Energetyka Słoneczna

2014

nr 1-4

26--32

The paper presents the preliminary results of the modernization of the Water Park (WP) in the North-Eastern part of Poland. It consists of application of such renewable energy sources (RES) systems as solar photovoltaics (PV) and installation of solar collectors, as well as supply and exhaust ventilation with modern heat recovery and heat pump, and also recovery of sewage heat. The predicted energy performance has been compared with that achieved during the WP operation immediately after the modernization closure. On this basis, increase in the WP energy system efficiency as well as economic and ecological effects have been evaluated preliminarily.

On a methodology for blending to obtain ternary formed fuels from waste

Łach J., Poskrobko S., Tomaszewicz-Załuska D.

Archives of Thermodynamics

2009

Vol. 30, no. 3

3-28

The paper presents a description of the mathematical formalism for blending to obtain ternary formed fuels from waste. The methodology assures obtaining fuels of required technology properties that result, for example, in a limited gram fraction of chlorine in dry mass of fuel, and an appropriate calorific value in the working state. The procedure results makes it possible to determine mass fractions of particular components of produced formed fuels, which in turn creates a possibility of performing stoichiometric calculations for both total and complete combustion. The modeling of both technological as well as calorific and emission properties of fuels from waste at their initial formation stage can have a significant importance for the implementation of new technologies of thermal waste processing, i.e. the production of synthetic fuels for power industry.
