One of the most promising approaches to tackle the high emission rate of carbon dioxide is the use of Carbon Capture and Storage (CCS) technology. This technology aims at capturing carbon dioxide from power stations and other industrial facilities, compressing, and then transporting it to underground storage locations. Three technological routes for carbon capture from power plants exist: pre-c...

Developing more efficient integrated MSW management plans necessarily involves complex decisions where tradeoffs between environment performance and cost and must be carefully analyzed. For instance, how does the cost and environmental performance of a MSW management system change if we include or exclude a specific material (e.g., glass, paper, plastic, metal) from our recycling program? And s...

Under certain conditions, a recent method of Barlet and Koziarz [2] constructs enough holomorphic functions to give a direct proof of the Stein condition for a cycle space. Here we verify those conditions for open G0–orbits on X, where G0 is the group of a bounded symmetric domain and X is its compact dual viewed as a flag quotient manifold of the complexification G of G0 . This Stein result wa...

In this paper, an experimental investigation on achieving ultra-low raw emissions in a diesel/methanol dual fuel engine based dual-loop EGR was carried out. The effect of (High pressure and low EGR) the combustion, performance methanol has been studied comprehensively. results show that NO x (<0.4g/kWh) PM (<10 mg/kWh) can be achieved simultaneously diesel with help EGR. combustion phase ...

Combustion instabilities arise owing to a two-way coupling between acoustic waves and unsteady heat release. Oscillation amplitudes successively grow, until nonlinear effects cause saturation into limit cycle oscillations. Feedback control, in which an actuator modifies some combustor input in response to a sensor measurement, can suppress combustion instabilities. Linear feedback controllers a...

Driven by the Paris agreement and tightening IMO regulations, marine sector is focusing on lowering engine emissions moving to low-carbon fossil or renewable fuel such as methane. The dual-fuel concept allows usage of methane main energy-source in diesel engines. A small pilot injection acts an ignition source for premixed It was investigated how NOx formation, mainly taking place during combus...

Hypersonic air-breathing engines rely on scramjet combustion processes, which involvehigh speed, compressible, and highly turbulent flows. The combustion environment andthe turbulent flames at the heart of these engines are difficult to simulate and study in thelaboratory under well controlled conditions. Typically, wind-tunnel testing is performedthat more closely approximates ...

The authors applied one-dimensional (1-D) simulation and 3-D Computational Fluid Dynamics (CFD) simulation to evaluate the potential of in-cylinder control methods on a low-speed 2-stroke marine engine to reach the International Maritime Organization (IMO) Tier 3 NOx emissions standards. Reducing the combustion temperature is an important in-cylinder measure to decrease NOx emissions of marine ...

It is becoming increasingly important to develop effective combustion technologies for low calorific industrial gases (LCIG) because of the rising energy demand and environmental issues caused by extensive use fossil fuels. In this review, prospect these opportunity fuels in China discussed. Then, recent fundamental engineering studies LCIG are summarized. Specifically, differences between trad...
