| Abstract: | This paper analyzes existing questions and reasons of ash conveying system,and proposes the technical reformation measure that are using throttle orifice for ash conveying equipment,and confirms all throttle orifices gauge of No.5-8 ash conveying system in some power plant through a series of tests,points out that the reformation makes the materials uniformity higher in dual-tubes ash conveying system,and at the same time reduces the pressured air consumption,and improves the unit operation economy. |
| Keywords: | boiler pneumatic ash conveying system ESP dual-tubes throttle orifice |
