Product Name: Steel Economizer Heat Exchanger for Verial Fluids Model NO.: BYECO- Type: Boilers Head Range of Applications: Power station, Life, Industrial Fuel: Coal Surface Treatment: Painted Customized: Customized Certification: CE, ISO Using: steel Making/Coal Coking Function: Wast Heat Saving Befinet: Low Cost Trademark: BOYU Transport Package: Export Package Specification: Steel or stainless steel Origin: Shandong HS Code: 8419500090 Product Description Steel Economizer Heat Exchanger for Verial fluidsEconomizer Specification:Economizer is aheat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas. The latest technology boiler spiral finned tubes economizer typically transfers this waste heat to the boiler's feed-water or return water circuit, but it can also be used to heat domestic water or other process fluids.Introduction:Our enconomizer is squeezing by high frequency welding method and the technology of steel strip according to certain structure automatically, continuous spiral welding outside the light tube wall, and then the other reserved part light tube bending, combination according to the requirement. As aresult, the diameter and length under the same conditions, it has larger heat transfer area.In boilers, Economical low installation costs better performance boiler economizer for CFB boiler are heat exchange devices that heat fluids, usually water, up to but not normally beyond theboiling point of that fluid. Economical boiler economizers are so named because boiler economizers for water heating can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in aboiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. Better performance boiler economizers are adevice fitted to aboiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (thefeed water).Parameter:NameEconomical low installation costs better performance boiler economizer for CFB boilerspecifications of finned tubeunit(mm)Bare pipe(od)25-165bare pipe(thick)2-8finned thicks0.6-3.0finned height5-30finned tube thread pitch5-30finned tube length</=12000Remark1.Other specifications outside the table should be proposed, it is negotiable.2.Generally speaking, the height of the fin <=1/2d3 The spiral finned tubes produced by our company are manufactured according to the principle:JB/T6512-92 DG1020-97Our Feature1H-fined tubeOur economizer is squeezing by high frequency welding method and the technology of steel strip according to certain structure automatically, continuous spiral welding outside the light tube wall, and then the other reserved part light tube bending, combination according to the requirement. As aresult, the diameter and length under the same conditions, it has larger heat transfer area.The H-finned tube is formed by welding two steel plates with arcs in the middle symmetrically to the light pipe to form a fin. Because its cut shape resembles the letter "H", it is called an H-shaped finned tube (Figure 1). Its two fins are rectangular, often using flash resistance welding, high fusion rate with light pipe welding, high tensile strength of the weld, and good thermal conductivityThe H-finned tubes is arranged in a row. The direction of the circulating gas flue is parallel to the fins. The circulating gas can flow smoothly between the two fins, forming a relatively stable and uniform flue gas channel. The resistance is small, and its resistance is almost the same with the tube type one. For the spiral finned economizer, because the spiral fin guides the circulating gas to change the flow direction to form turbulence, and at the same time, the arrangement is staggered, the circulation area is correspondingly reduced, so it increases the resistance of the circulating gas for flue gas measurement and the load of the circulating fan.
