Abstract The method of increasing the technical resource 152 mm caliber howitzer, model 1981 aims to improve construction solution an essential subassembly this product’s structure, without affecting functioning howitzer and diminishing its safety stability in firing. For reason, article highlight aspects guiding sealing piston caliber, howitzer’s recuperator, using a polymer composite material...

Organic Rankine Cycles (ORC) and Trilateral Flash (TFC) are very similar power cycles; ideally, they have a reversible adiabatic (isentropic) compression, an isobaric heating, isentropic expansion cooling. The main difference is that for ORC, the heating includes full evaporation of working fluid (prior expansion); therefore, starts in saturated or dry vapour state, while TFC, terminates upon r...

The aim of the study is to develop a design an air-heating recuperator for purge ventilation system building inbuilt purpose utilizing lower-grade heat from gases and emissions with associated production thermoelectricity. An experimental as part unit has been developed. It includes thermoelectric source electromotive difference, which operates result conversion into electricity, allows lower-p...

Modern control design of large industrial plants relies strongly on modelling, while experimentation on the real system is extremely limited. The usable model should be intuitive and easily reusable to model potential plant adaptations or similar plants. In this paper some aspects of the modelling a recuperator plant consisting of four heat exchangers are presented. With the object-oriented mod...

The optimal design of a plate-fin recuperator of a 200-kW microturbine was studied in this paper. The exergy efficiency, pressure drop and total cost were selected as the three important objective functions of the recuperator. Genetic Algorithm (GA) and Non-dominated Sorting Genetic Algorithm (NSGA-II) were respectively employed for single-objective and multi-objective optimizations. By opt...

Abstract In the conditions of constant growth prices for consumed energy and competition in domestic market, rural commodity producers have a problem to reduce costs, since they make up significant share cost agricultural products. There are particularly high costs heat treatment meat dairy products grain. To thermal purposes, you can use secondary extraction its specific technological process....
