In JSDJ,Website:http://www.chinawasteheatboiler.com, we for always consider innovation to be the vitality of any company. By virtue of this belief, we are in a leading position in the field of waste heat recovery technologies with open scientific research mechanism. We established provincially recognized "Enterprise Technology Center" in 2006, and "Waste Heat Recovery Boiler R & D Institute" in 2013. Currently, there is a team of 78 brilliant engineers & researchers working in both center and institute. As a result of their hard work, we have consecutively been granted 36 patents on waste heat recovery technologies. We have built positive scientific cooperative relationships with many outstanding institutions and companies from China & abroad, including but not limited to Chinese Academy of Sciences, Tsinghua University, Northeast University, Sinopec, Bao-steel Group, SIEMENS VAI, Lugi, DURR, Kawasaki Heavy Industries, 3R A/S, Rio Tinto, etc. Our FirstsFirst direct-hood-type Sinter Cooler waste heat recovery boiler in the world came from JSDJ; First domestic ASH boiler super-heater for cement kiln waste recovery boiler came from JSDJ; First domestic bypass-wind cement kiln waste heat recovery boiler came from JSDJ;First Rotary Hearth waste heat recovery boiler with IPR in China came from JSDJ; Dry Quenching Coke waste heat recovery boiler with the highest quenching capacity in China came from JSDJ; First water-tube-type Electric Arc Furnace waste heat recovery boiler in China came from JSDJ; First Waste Sulfuric Acid waste heat recovery boiler in China came from JSDJ. QASOverviewWith the five essential systems of "operation management system, quality assessment system, sales responsibility system, process assessment system and R& D incentive system" being our foundation, we keep driving our corporate standardization developmentto ensure the operational precision of all departments. Trace-ability The quality assurance system of "integrated six major steps" is exclusively implemented, including material trace-ability system - material recheck system - manual operation records traceable system - process performance system - process specification manual - quality standard manual.When materials are inspected and delivered into respective workshops, an inspection serial number is assigned as per batch number of each boiler; during manufacturing process, materials are delivered according to each inspection serial number; while separating materials, the inspection serial number is shifted onto all sub-items & parts as per stipulated positions.Process cards and inspection records are respectively applied to log the delivery of inspection serial number of process-materials (including welding materials). All product records are input into the product quality files upon completion.  All pressure parts are identified by welder-code seal at welding lines to thoroughly ensure the trace-ability of all parts and accessories. Five Major Centers NDT Center, Physical and Chemical Testing Center, Product Inspection Center, Weld Testing Center, Metering & Measurement Center are established to work with the entire production process for eliminating any production error and insufficiency.Production TechnologiesOverviewIn order to deliver the best product to our customers, we never subcontract our key pressure parts out. Instead, we choose to invest in high-tech machinery and equipment to ensure product quality. In addition, process execution force is emphasized in each process & procedure during production for consistent perfection and self-improvement. It is also to ensure the precision of four major components, i.e. steam drum, header, membrane wall and coil (serpentine-tube). To every step is given the most rigorous attention and most suitable equipment & procedure.
