Seamless Customized Heat Recovery Steam Generator to Improve the Production Efficiency

✎ What is HRSG?

• Along with sustainable development,recycling economy,energy conservation and low-carbon economy ideas put forward one by one.our cogeneration industry has experienced from scratch,small to large development process.
• Cogeneration production process is converted waste heat to electrical energy technology.Cogeneration not only energy,as well as environmentally.Important cogeneration equipment room is HRSG.
• HRSG generator is divided into six circulation loops, each circulation loop is composed of the down pipe and up pipe, each section of the flue feed water from the boiler tube through the down pipe into the lower collection box of each flue into each heating surface, water through the heating surface to produce steam into the inlet collection box, then by the rising pipe into the pot.All flanges are connected with flanges.

✎ What should be cared about HRSG?

1. The heating surface of this type employs suspension structure which is good for absorbing boiler expansion and makes it safe in operation.
2. The three cast-off mixed burning and blown gas waste heat boiler uses special sealing devices to reduce boiler air leakage and improve boiler efficiency.
3. The heating surfaces employ reasonable flue gas velocity design to prevent soot accumulation.
4. Straight-arrangement adopted keeps the heating surface clean and improve the heat exchange efficiency.
5. This equipment organizes flue gas dynamic field to the flow of flue gas steady and uniform.
6. The convection tube-bank employs assembled structure with fast installation and low cost.

✎ What are the features of HRSG?

1. Modular structure, optimize the design, layout reasonable, energy efficient.
2. Spiral fin tubes to improve heat transfer efficiency.
3. All pipes and headers with hydrophobic Hassle elbow, easy and thorough for drain off water.
4. Using suspension structure and insulation within the outer shield in the form of thermal expansion freedom, heat a small.
5. Optimizing select each heating surface pressure drop within the working fluid, the working fluid velocity distribution, safe and reliable water circulation.
