Membrane and fin tube economizer economizer similar Shengda membrane boiler economizer is between two light tubular welded pipe straight portion continuous flat diaphragm, flat diaphragm thickness of 2-3mm. Diaphragm economizer economizer heat transfer better than fluorescent tubes, and heat transfer in the same conditions, the metal content of the former less, low cost, and wear light, reliable, easy Sootblowing than fin economizer . From (Shengda) membrane economizer structural point of view, the entire stack economizer tube row split lengthwise series of small flue gas channel, the objective has played a role in sharing the flue gas velocity field, which can be eliminated smoke or improve local partial wear caused by high-speed phenomena; on the other hand due to flow around the diaphragm effect is good, so that ash-containing flue gas flow state is formed in the film tube bank small flue gas channel, so that the flue gas large ash particles tend middle, tiny ash particles near the heated surface flow, which tends to produce the effect of flow in the membrane economizer large fly ash particles. Yancheng Shengda Petrochemical Machinery Co., Ltd. specializes in producing A-class boiler parts -, - through the measurement of the province to ensure that the identification and implementation of good corporate standards of qualified acceptance, were given the People's Republic of China special equipment manufacturing license (pressure piping components), China People's Republic of special equipment manufacturing license (A-class boiler parts), BOP and BOP control device production license, the national industrial production permit, and through the IS09001 quality management system certification, IS014001 environmental management system certification, 0HSAS18001 Occupational Health and Safety Management System Certification and the US API certification (16A, 6A, 16C), has the right to use API monogram, has been awarded the contract and trustworthy units. Companies registered capital of 51 million yuan, covers an area of ??61,800 square meters, construction area of ??32,000 square meters. Currently employs more than 180 employees, including 36 professional engineering and technical personnel. Have included ordinary cutting machines, machining centers, high-precision CNC lathes, high precision grinding machines, universal bending machine, universal hydraulic machine, heat treatment furnace, and advanced production and testing equipment more than 180 pieces (sets), strong technical force, hot and cold processing equipment complete, comprehensive means test.

Because membrane economizer wear resistance, more and more people pay attention, there are many plants in the power system will be changed to the light tube economizer economizer membrane. Unlike optical film manufacturing economizer economizer tubes, fluorescent tubes economizer shall meet the criteria when processing, but also have higher requirements, the diaphragm tube must be parallel, to reduce the residual welding blades produced Applications must retain no undercut welding certificate, floating welding, porosity, slag and so on. Membrane economizer tube rows rigid, flexible compensation capability is low compared with the light pipe economizer, therefore, when the group is difficult to weld couplet box installation, which requires the production of tube rows with high quality; prevent the installation lifting, transportation deformation; Dimensions actinomycetes between standard pipe exhaust positioning and assembly, exhaust pipe from the adjustment uniformly tight, pipe arranged in rows have enough expansion gap discharge tube, designed to ensure the flue gas flow rate, to eliminate smoke gas corridor, so reducing the wear and tear after economizer transform and improve the life of the economizer.
