For further research on temperature field and thermal strain of dry gas seal, numerical simulation is carried out. It is discovered, the temperature of rotating ring declined gradually from inside to outside, maximum temperature (85.45°C) appeared at the inner side of the face, minimum temperature (72.18°C) appeared at the left outside of the ring, with a temperature difference of 13.27°C. The face...
H2S evolution during different oil shale samples pyrolysis was studied in fixed bed in the nitrogen atmosphere. The results show the H2S evolution is influenced by pyrolysis conditions and properties of oil shale. The yield of H2S released for two samples had a marked change at 300-600??C of final temperature and 5-50??C/min of heating rate. Both the H2S yields of two samples increase with grain size...
An experimental study on sulfur release and adsorption during coal partial gasification and combustion is conducted in a 1MW circulating fluidized bed (CFB) poly-generation system. Limestone is added to gasifier as a sorbent of sulfur produced, where part of the sorbent flowed through a bi-directional returning feeder into combustor and another part returned to gasifier. The results show that limestone...
