Transformation characteristics of sodium in Zhundong coal under circulating f...
QQ图片20171121133900.png
 
  In this study, the transformation characteristics of sodium in Zhundong coal were investigated during oxygen-rich gasification in a circulating fluidized bed (CFB) reactor. The reactor, with a fuel treatment rate of 0.4 t/d, was specially made for experiments on thermochemical conversion of high alkali coal. Th...

  Absorption refrigeration systems are a promising way to reduce electricity consumption in the field of refrigeration and cooling. To improve the thermal energy utilization performance of the absorption refrigeration system, an absorption/absorption–compression refrigeration system with a large working range is...
Investigation of the effects of Ni-based alloy DZ125 on the normal spectral e...

  The normal spectral emissivity of Ni-based alloy DZ125 during oxidation is experimentally measured at 810, 916 and 998 _C for 12 h in air over the wavelength from 1.35 to 2.35 lm. The combined standard uncertainty of the normal spectral emissivity is less than 3%. The oscillations of the emissivity and the effe...
Loop thermosiphon as a feasible cooling method for the stators of gas turbine
QQ图片20171121115027.png
 
  A stator sample of a gas turbine was developed with loop thermosiphon structure to seek a feasible cooling method for high-temperature stators of gas turbine. The sample was comprised by 8 hollow vanes and a cooling tube. Its inner space was filled by sodium-potassium alloy (Na-K) to become a loop thermosiphon ...
Hydrogen production from chemical looping steam reforming of glycerol by Ni b...
QQ图片20171121113845.png
 
  This paper describes the synthesis of a series of Ni based Al-MCM-41 oxygen carriers with and without Ce promoter and their application in chemical looping steam reforming of glycerol. The Al-MCM-41 is derived from montmorillonite. The oxygen carriers were prepared by direct-synthesis and post-synthesis method....
Experimental study of jet impingement heat transfer on a variable-curvature c...
QQ图片20171121113318.png
 
  In this paper, extensive experimental investigation of the heat transfer characteristics of jet impingement on a variable-curvature concave surface in a wing leading edge was conducted for aircraft anti-icing applications. The experiments were carried out over a wide range of parameters: the jet Reynolds number...
The stall inceptions in an axial compressor with single circumferential groov...
QQ图片20171017102700.png
 
  Circumferential groove (CG) casing treatment is known to be a good method to improve the stall margin of axial compressor. Recent studies on single groove indicate the stall margin improvement (SMI) is significantly affected by groove’s axial location, which means the effects of the groove on the passage flow ...
Slagging behaviors of high alkali Zhundong coal during circulating fluidized ...
QQ图片20170930104438.png
 
  Slagging behaviors of high alkali Zhundong coal during circulating fluidized bed (CFB) gasification were investigated in a 0.4 t/d CFB test rig for 72 h, with air-cooled ash deposition probes located along the gas flow direction. The microstructure, chemical compositions and mineral crystalline phases of ash we...
Hydrogen production from chemical looping steam reforming of glycerol by Ni-b...
QQ图片20161027171549-.jpg
 
  Hydrogen production from chemical looping steam reforming (CLSR) of glycerol was studied by Ni-based oxygen carrier in a fixed-bed reactor. For the fixed-bed reactor configuration, solid Ni-based oxygen carrier is stationary and alternatively exposed to reducing and oxidizing conditions by periodically switchin...
Influence of type of burner on NO emissions for pulverized coal preheating me...
QQ图片0.jpg
 
  Coal preheating method has demonstrated great potential to reduce NOx emissions. Interestingly, whether this method is suitable for all types of burner remains to be elucidated. Four types of burner with different air staging schemes were studied in the present experiments. With coal preheating method, numerous...
