Distribution to : Sizing Data : 鬼屋魔影小游戏VHE Heater 56 dome with high pressure steam coils. Total coil volume (including manifold) is 298 liter. GekaKonus High Pressure Boiler : NUK HP 1500 Type : Natural circulation boiler Boiler design pressure : 95 bar Boiler water volume : 875 liter Filling water volume : 1,050 liter (1.2 x boiler water volume) High pressure piping DN100 lected with Steam piping : 41m length minimum (plea e actual required) Condensate piping : 40m length minimum (e actual required) This minimum length must comply for water-to-steam expansion requirement. (refer to GekaKonus installation instruction manual) Actual piping length required to suit layout : High pressure piping actual required to suit layout will be : 5369DN100 steam piping : 46 m actual length (5 meter more than minimum) DN100 condensate piping : 43 m actual length (3 meter more than minimum) No. of 90o elbows calculated : DN100 : 14 pcs for steam line, 12 pcs condensate line DN 50 : 2 pcs for condensate line 界面设计工具No. of reducer required : DN100/DN80 (1 pc), DN100/DN50 (2 pcs) No. of tee required : DN100 (1 pc) Piping specification : DN100 (4”) schedule 80 amless carbon steel pipe meeting DIN material grade St 35.8 III standard. Pipe dimension approx OD 114.3mm x 8.0mm thick minimum. Piping is commonly in 6m length. As a minimum, all welding joints to be : - 100% visual examination. 啮虫目- 10% radiographic examination on randomly lected (completed) butt welds. - 10% examination of welding ams by dye penetration test - hydrostatic tested according to pressure stated in boiler name plate (together with boiler and VHE heater). Bursting disc and safety valve to be removed during hydrostatic test. - welded by certified welder only. Steam and condensate piping to be slope towards the boiler at least 5% slope which is approximately 3o slope. Steam and condensate piping to be installed in zig-zag routing (as shown in 3-D drawing) to cushion the thermal expansion. Venting valve to be installed at the higher position of the steam piping. Insulation requirement : High pressure boiler already provided with insulation by Gekakonus. No additional insulation is required. VHE Heater 56 requires insulation area approx 18m2 of at least 150 mm thickness. Recommendation of insulation type for VHE Heater : : Fibertex 650 rockwool blanket 勺子的英语单词Density : ~100 kg/mmoney is not everything3 Standard thickness available : 2 x 75mm rockwool 授权委托书英文Cladding : Aluminium coil 0.7mm x 4 ft Accessories : G16 G.I. binding wire, lf tapping screw, silicon alant Heat loss from VHE Heater estimated at : 6,000 W Piping insulation thickness required is minimum 63 mm with total length estimated 89 meters. Recommendation of insulation type for piping : SPI 650 rigid rockwool pipe ctional insulation Density : 140~150 kg/m3 Standard thickness available : 63 mm rockwool Standard unit length : 1.2 meter Cladding : Aluminium coil 0.5mm x 4 ft Accessories : G20 G.I. binding wire, lf tapping screw, silicon alant Remark : thickness recommended for piping insulation is the minimum required with pipe temperature assumed as 300oC and insulation surface temperature not above 50oC as the basis of lection, with surrounding still air assumed not lower than 20oC. Heat loss from total piping estimated at : 9,800 W Remember to ensure the aluminium cladding will not be in direct contact with hot surfaces. This will minimize the heat loss by conduction. Water requirement : 爱祖国演讲稿Demineralid or distilled water (condensate is not permitted) added with a concentration of 30 g/m3 trisodium phosphate for minimum conductivity required for the operation of the low water level detection electrode as well as protection against corrosion. Others : VHE Heater to be located with oil outlet at least 1 meter above oil inlet to deodorizer. VHE Vapour duct to be connected to a position above the prestripper. The first piping to be connected from the boiler to be minimum 2 meters vertical. | |
