Specification for performance test of surface condenser1 ScopeThis standard specifies the basic principles and methods of instrument selection, test procedures and test data processing for surface condenser performance tests. This standard applies to the performance test of water-cooled and surface condensers operating under vacuum.2 Normative referencesThe following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated references, the latest version (including all amendments) applies to this document. GB/T 8117 (all parts) Steam turbine thermal performance acceptance test procedure GB/T 13930 Water ring vacuum pump and water ring compressor gas volume measurement method3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Condenserpressure The absolute static pressure maintained at the steam channel 300mm above the first row of condenser tubes in the condenser shell. 3.2 Condenserheatload The heat transferred from steam to cooling water in the condenser per unit time. 3.3 Overall heat transfer coefficient After considering the comprehensive factors, the heat transfer of the condenser per unit time, unit surface area, and unit temperature difference. 3.4 Cleanlinessfactor Under the same operating conditions, the ratio of the heat transfer coefficient of the old condenser tube to the new tube or clean tube. 3.5 Condensate subcooling The difference between the saturation temperature of steam and the temperature of condensed water under condenser pressure. 3.6 Dissolved oxygen in the condensate The amount of dissolved oxygen per unit in condensate. 3.7 Condensercirculatingwaterpressurelosses The difference between the static pressure at the inlet and outlet of the cooling water.4 symbolsThis standard uses the symbols and subscripts, superscripts and their definitions specified in Table 1, Table 2, and Table 3, unless otherwise specified. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 37753-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 37753-2019_English as soon as possible, and keep you informed of the progress.
