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?
- The heating surface of this type employs suspension structure which
is good for absorbing boiler expansion and makes it safe in
operation.
- 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.
- The heating surfaces employ reasonable flue gas velocity design to
prevent soot accumulation.
- Straight-arrangement adopted keeps the heating surface clean and
improve the heat exchange efficiency.
- This equipment organizes flue gas dynamic field to the flow of flue
gas steady and uniform.
- The convection tube-bank employs assembled structure with fast
installation and low cost.
✎ What are the features of HRSG?
- Modular structure, optimize the design, layout reasonable, energy
efficient.
- Spiral fin tubes to improve heat transfer efficiency.
- All pipes and headers with hydrophobic Hassle elbow, easy and
thorough for drain off water.
- Using suspension structure and insulation within the outer shield
in the form of thermal expansion freedom, heat a small.
- Optimizing select each heating surface pressure drop within the
working fluid, the working fluid velocity distribution, safe and
reliable water circulation.
