The energy and exergy flows were consi.ered from 2006 to 2011. The overall energy effi.i.ncy ranges from 19.15% i. 2006 to 20.19% i. 2011 wi.h a mean of （19.96±0.23）% whi.e the overall exergy effi.i.ncy ranges from 4.34% i. 2006 to 4.40% i. 2011 wi.h a mean of （4.31±0.059）%.

The study presented here was carri.d out to ob.ai. the actual soli.s flow rate b. the comb.nati.n of electri.al resi.tance tomography and electromagneti. flow meter. A new i.-si.u measurement method b.sed on measurements of the Electromagneti. Flow Meters （EFM） and Electri.al Resi.tance Tomography （ERT） to study the flow rates of i.di.i.ual phases i. a verti.al flow was proposed. The study was b.sed on lab.ratory experi.ents that were carded out wi.h a 50 mm verti.al flow ri. for a numb.r of sand concentrati.ns and di.ferent mi.ture veloci.i.s. A range of sand slurri.s wi.h medi.n parti.le si.e from 212 μm to 355 μm was tested. The soli. concentrati.n b. volume covered was 5% and 15%, and the correspondi.g densi.y of 5% was 1078 kg/m^3 and of 15% was 1238 kg/m^3. The flow veloci.y was b.tween 1.5 m/s and 3.0 m/s. A total of 6 experi.ental tests were conducted. The equi.alent li.ui. model was adopted to vali.ate i.-si.u volumetri. soli.s fracti.n and calculate the sli. veloci.y. The results show that the ERT techni.ue can b. used i. conjuncti.n wi.h an electromagneti. flow meter as a way of measurement of slurry flow rate i. a verti.al pi.e flow. However i. should b. emphasi.ed that the EFM results must b. treated wi.h reservati.n when the flow pattern at the EFM mounti.g posi.i.n i. a non-homogenous flow. The flow rate ob.ai.ed b. the EFM should b. corrected consi.eri.g the sli. veloci.y and the flow pattern.
