Improving Flexibility and Performance of Staged Pressurized Oxy-Combustion

Enthalpy Calculation for Pressurized Oxy-coal Combustion

Oxy-fuel combustion is recognized one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned under the pressure of 6MPa and oxygenenriched conditions, the high temperature and high pressure gaseous combustion product is composed of 95% CO2 and water-vapor, with the rest of O2, N2 and so on. However, once lauded as classic approach o...

Oxy-coal Combustion Studies

Homogeneous oxidation of mercury during combustion: A comparison between combustion in air and oxy-combustion

Since oxy-combustion is a relatively new technology, many problems associated with the behavior of coal in this novel combustion process still need to be solved. In particular, there is a lack of knowledge regarding the behavior of toxic trace elements, and there is a need to determine whether trace element distribution among the by-products and emissions to the environment, is comparable with ...

Oxy - fuel combustion of coal and biomass blends

The ignition temperature, burnout and NO emissions of blends of a semi-anthracite and a high-volatile bituminous coal with 10 and 20 wt.% of olive waste were studied under oxy-fuel combustion conditions in an entrained flow reactor (EFR). The results obtained under several oxy-fuel atmospheres (21%O2-79%CO2, 30%O2-70% CO2 and 35%O265%CO2) were compared with those attained in air. The results in...

the effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
