The stringent regulations set by the International Maritime Organization on pollutant emissions combined with rise in fuel prices have stimulated research cleaner fuels and new propulsion systems. This study describes a method for evaluating alternative technologies that can be utilised marine sector to replace heavy oil diesel engines, thus improve their performance while lowering carbon dioxi...

The ultra-supercritical (USC) double-reheat technology is an immediate area of research focus in China, since the thermal efficiency USC unit higher than single-reheat unit. parameters and capacity China have made major breakthroughs, units are as high 47–48%, which highest world. boiler one most important devices for unit, design concept precision a vital effect on operation power station. dif...

This paper examines novel wave rotor topping cycles that incorporate low-NO,, combustion straregies. This approach combines two-s rage ''rich-quench-lean'· ( RQL) combustion with inrermediate expansion in th...

Abstract A new mathematical framework for optimal synthesis, design, and operation of triple-pressure steam-reheat combined-cycle power plants (CCPP) is presented. superstructure-based representation the process, which embeds a large number candidate configurations, first proposed. Then, generalized disjunctive programming (GDP) model derived from it. Series, parallel, combined series-parallel ...

Recently Garcia Bellido et. al. have proposed that electroweak baryogenesis may occur at the end of inflation, in a scenario where the reheat temperature is too low for electroweak symmetry restoration. I show why the scenario is difficult to test reliably by classical field techniques on the lattice.
