  • Thermo dynamical assessment of the digestion process

    ABSTRACT Digestion of sludge was mostly seen as a stabilisation process prior to disposal or land application. During the last years there is an increased interest to use biogas as alternative energy source to replace the use of fossile fuels and giving the digestion process an economical value. In this paper a correlation is derived to combine the degradation of sludge with the amount of ...

  • Why Does the Non-Orthogonal Sonic Anemometer Underestimate

    The performance of non-orthogonal sonic anemometers has been the subject of much discussion in recent years.  It followed findings that they underestimated vertical winds and vertical heat fluxes by 10-15%.  For agricultural and forestry scientists who depended on them for their large-scale energy balance studies this was a bad surprise.  They had collected turbulence data from ...

  • Minimizing flow distortion errors in a sonic anemometer

    This paper describes a simple approach to minimizing probe-induced flow distortion errors in a three-axis sonic anemometer. By separating the three axes, mutual interference between the transducers and supports in the three arrays is reduced. Only a transducer shadow correction determined from wind tunnel tests is needed to obtain measurements that are virtually insensitive to probe orientation ...

  • Comparisons of models with data: effects of averaging time as indicated by sonic anemometer measurements

    For continuous sources, plots of predicted against observed gas concentrations often display considerable scatter. These differences are apparent even when the averaging times for the models and data match. Possible sources of error in the observations are shifts in direction of the mean wind or disturbance by intermediate- and large-scale eddies. Errors in predictions may arise from the ...

  • Thermo-economic efficiency of low capacity coal-based power plants

    The method of estimation of thermo-economic factors, allowing the justification of the construction of low capacity coal-based power plants has been developed in the present paper. The C-curve method applied for thermo-economic analysis is used here for determination of the optimal ratio between specific exergetic and cost-performance factors. The results of the analysis show that for coal-based ...

  • Steam Turbine Rotor Transient Thermo-Structural Analysis and Lifetime Prediction

    Market requirements for faster and more frequent power unit start-up events result in a much faster deterioration of equipment, and a shorter equipment lifespan. Significant heat exchange occurs between steam and turbine rotors during the start-up process and even more intensive heat exchange takes place during the condensation phase in cold start-up mode, which leads to further thermal stresses ...
