新《锅壳锅炉受压元件强度计算》标准虽然还未正式审批,为了尽早掌握与运用,我厂近期开发的卧式内燃油炉的设计就按新标准进行,现就WNS4—1.25—Y型锅炉的管板设计为例,介绍並探讨新标准的运用。 1.WNS4—1.25—Y炉采用的结构型式 参照国内外大量的油炉样本资料並从燃烧机性能考虑,决定配用进口燃烧机,炉体结构采用中心回燃型式（见简图1）。综合燃烧机及各方面因素,选定炉胆内径为φ1000mm,锅壳内径为φ1800mm,锅筒长4260mm。 2.管板设计与探讨 （1）管板结构
The new “shell boiler pressure element strength calculation,” although the standard has not yet been formally approved, in order to grasp and use as soon as possible, the recent development of our plant horizontal internal combustion furnace designed to press the new standard, WNS4-1.25-Y The boiler tube design, for example, introduces and discusses the use of new standards. 1. The structure of WNS4-1.25-Y furnace is based on a large number of oil furnace sample data at home and abroad and from the burner performance considerations, decided to use imported burner, the furnace structure using the center back to burn type (see Figure 1). Comprehensive combustion machine and various factors, the selected furnace diameter φ1000mm, pot diameter φ1800mm, drum length 4260mm. 2. Tube plate design and discussion (1) tube plate structure
