With a view of exploiting renewable biomass energy as a highly efficient and clean energy, liquid fuel from biomass pyrolysis, called bio-oil, is expected to play a major role in future energy supply. At present, fluidized bed technology appears to have maximum potential in producing...

In this paper, emulsion fuels from crude bio-oil and its molecular distillation fractions were prepared by single ultrasonic and ultrasonic-mechanical emulsification. The results showed that the emulsions from crude bio-oil and 0# diesel had the best stability, with a stability time of 31 days....

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...

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...

In developing a mathematical model for a CFB boiler we use earlier work. Our model includes mathematical descriptions of the underlying physical and chemical processes. It has been applied to simulation of a 12 MW CFB boiler. The calculations agree well with test results.

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...

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...

Oscillating flows have fundamental effects on the heat and mass transfer of Stirling engines and gas springs. A complex velocity model was proposed to describe the fully-developed laminar oscillating flow through introducing complex functions and simplified control equations. The maximum...

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...

Promoting the nitrogen oxide (NOx) absorption step is the major challenge for simultaneous removal of sulfur dioxide (SO2) and NOx in wet flue gas desulfurization. This paper studied NOx absorption and absorption product formation in limestone slurry. The effect of CaCO3 concentration, NOx...
