High temperature air combustion is an advanced technology to control NO emission, which carries out the combustion at highly preheated air and dilute oxygen conditions. The combustion performance of natural gas with highly preheated air was numerically simulated in an industrial furnace with a longitudinal and swirling burner respectively. The probability density function (PDF) combustion model, discrete ordinate (DO) radiation model and the Reynolds stress turbulent model (RM) were adopted for the modeling. Results showed that swirling burner was effective to reduce the final NO emission and improve the fuel burnout. When the longitudinal burner was substituted by a swirling burner with 180° swirling angle, the NO emission decreased from 35.2 ppm to 12.3 ppm, while the maximum and mean temperature in the furnace increased 38K and 58K. The CO emission also decreased from 379 ppm to 29 ppm, which implied a better burnout was achieved.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"22 1","pages":"6047-6050"},"PeriodicalIF":0.0,"publicationDate":"2011-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73351725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And the relationship between mechanical properties and mass loss was analyzed. The results show it is the effective way to slow down such abrasion erosion by strengthening the mechanical properties. The ability of anti-abrasion of slag concrete is decreased with the increasing water-binder ratio. For the slag concrete with made with a water to binder ratio of 0.35, the abrasion erosion rate was the minimum for the concrete with 45% slag content, namely, such a concrete has the best abrasion erosion resistance.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"25 1","pages":"5595-5597"},"PeriodicalIF":0.0,"publicationDate":"2011-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75349631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The boundary conditions are very complex and it is much influenced by the sensitivity factors such as temperature, defect, and redundancy. Combined with a project example of flexible giant Ferris wheel, mechanical performance for rim and cables were analyzed. The rational initial prestress was chosen to optimize the structural behaviour. The stability analysis considering the initial imperfection was performed to research the nonlinear buckling characteristics. Taking the geometric and material nonlinearity into account, the elasto-plastic limit bearing capacity analysis revealed the structural characteristics comprehensively. The results indicated that: nonlinear characteristics of flexible giant Ferris wheel is obvious due to the introduction of prestressed cable; mechanical performance of the structure depends on the initial prestressing force; the wheel consisting of radiate spoke cables and space truss provides strong lateral stiffness as well as torsional stiffness and the stability performance is favorable; the plastic development mechanism is beneficial and the elasto-plastic limit bearing capacity is so large that the wheel can satisfy the need both for operating condition and for storm condition.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"24 1","pages":"468-471"},"PeriodicalIF":0.0,"publicationDate":"2011-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75495085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
