A method based on fractal geometry is suggested to simulate the porous structure of calcined limestone, in which a model similar to the Menger sponge is employed for the porous calcine. The bulk fractal dimension is calculated on the basis of the experimentally obtained pore-size distribution...

A new system has been developed for clean and highly efficient utilization of coal. The coal is first gasified and the fuel gas is then used for industrial purposes in town gas or as a fuel for gas turbines. The char residue from the gasifier is burned in a circulating fluidized-bed combustor to...

Lignite-based polygeneration system has been considered as a feasible technology to realize clean and efficient utilization of coal resources. A newly polygeneration system has been proposed, featuring the combination of a 2×300MW circulating fluidized bed (CFB) power plant and atmospheric...

Based on CO2 acceptor gasification technology, a biomass anaerobic gasification technology for H2 production was proposed. Utilizing thermodynamic equilibrium calculation software FactSage 5.2, the rules of biomass/CaO/H2O and C/CaCO3/air reaction system involved in this H2 production technology...

This paper attempts to categorize solar stills into six sorts based on the design guidelines used in each device. The properties of these design guidelines are detailed and evaluated from the angle of enhancing the productivity of solar stills. Preferred design guidelines are recommended for...

Using the technology of spectral selectivity to integrate different solar power generators in a hybrid system is a feasible way to improve the optical-electric efficiency. This paper presents an 82-layer broadband optical interference thin-film filter matching with crystalline silicon...

In order to investigate the characteristics of the reaction between ammonium sulfite, the main desulfurizing solution, and the flue-gas-contained sulfur dioxide during the process of ammonia-based WFGD (wet flue gas desulfurization) in a power plant, the gas-liquid absorption reaction between...

A Lambertian CCD-camera method is convenient to measure concentrating radiation fluxes, where a crucial factor, a calibration factor, always varies with spectra and brings errors. In this paper, a new calibration method is proposed based on spectral normalization calculation and tries to reduce...
