Insulation performance and buried depth of heating pipelines are the vital factors affecting energy loss directly pipelines. This study considers thermo-economic assessment insulation for district heating. The optimal thickness, energy-saving effect, payback period with five nominal pipe diameters, four fuel types, kinds materials, depths calculated. A numerical code is developed based on Life ...

On (b, c)-system at finite temperature in thermo field approach Abstract We construct the finite temperature field theory of the two-dimensional ghost-antighost system within the framework of thermo field theory.

A hybrid central tower thermo-solar plant working with a gas turbine is simulated by means of an in-house developed model and software. The considers the integration all subsystems. calculation heliostat solar field efficiency includes main losses factors as blocking, shadowing, attenuation, interception, cosine effect. simulation Brayton cycle for power unit irreversibilities in compressor tur...

The Organic Rankine Cycle (ORC) is a promising form of technology for recovering low-grade waste heat. In this study, a regenerative ORC system is established to recover the waste flue gas of 160 ◦C. Focusing on thermodynamic and economic performance while simultaneously considering the limitations of volume flow ratio (VFR) and the effect of superheat, working fluid selection and parameter opt...

BACKGROUND Uganda's banana industry is heavily impeded by the lack of cheap, reliable and sustainable energy mainly needed for processing of banana fruit into pulp and subsequent drying into chips before milling into banana flour that has several uses in the bakery industry, among others. Uganda has one of the lowest electricity access levels, estimated at only 2-3% in rural areas where most of...
