This study evaluates the performance of 12 models to estimate hourly diffuse solar irradiation on inclined surfaces from those measured on horizontal surfaces. Total solar irradiation incident on a tilted surface consists of three components including: beam, diffuse and reflected from the...

There are four strategies to combating global warming, namely by directly reducing greenhouse gas emissions, or indirectly through expanding renewable energy employment, more efficient use of energy, or a wide range of climate policies. This study reports a bibliometric analysis of direct carbon...

Oxy-fuel combustion is one of the clean coal combustion technologies for CO2 capture. However, post-combustion capture is studied as a challenged technology against oxy-fuel combustion. This paper presented the life cycle assessment (LCA) of these two CO2 capture technologies used in the 300 MW...

Oxy-coal combustion produces a combustion environment that contains large amounts of CO2, H2O compared to conventional air combustion. Silica (SiO2) is a major component of the mineral impurities in coal and the vaporization of silicon containing species controls the initial phase of formation...

The H2O concentration in real oxy-fuel combustion atmospheres is significantly higher than that in conventional air combustion, which strongly affects the combustion characteristics of pulverized coal. This study studies the effect of H2O on pulverized coal combustion behaviour in O2/CO2...

The effect of varying the fuel and oxidizer composition on flame characteristics in a non-premixed oxy-methane flame was experimentally investigated in a lab-scale furnace with a slot-type burner. The fuel composition was varied in the range of XF,CH4 = 70∼100%, XF,H2 = 0∼15%,...

High CO2 purity products can be obtained from oxy-combustion power plants through a CO2 CPU (compression and purification unit) based on phase separation method. To ensure that CPU (with double flash separators) can be operated under optimal conditions, this paper focuses on single variable...
