Modeling the basis power in the systems for continuous transport of fluids and bulk materials

Abstract

This paper presents a novel developed model for calculating the totally useful power in the systems for continuous transport of fluids and bulk cargoes, allowing deeper and more functional analysis of the energy efficiency of this systems by physically based decomposition of the electricity consumption of a useful and unhelpful ingredient. The model consists of nine mathematical expressions by which, after determining the type of system, the physically required minimum possible power consumption can be calculated and compared with the total consumption. A pumping system for the transport of condensate water from a deaerator to the drum of a steam generator of a thermal power plant has been selected as the subject of the model demonstration experiment. In the investigation carried out, the basis power of the pumping system was 606.6 kW and the total losses were about 302 kW. Other energy efficiency indices have also been identified. The researches should be continued in the direction of algorithmization of the model and its justification mainly for the Type II systems.
