Can, high-temperature flue gas can take away 5%~15% (wherein 70% heat recoverable) of boiler heat supplying amount after burning.Flue gas
The recycling of waste heat reduces energy total flow and is of great significance for promoting boiler efficiency.
Heat pipe (or heat pipe) is a kind of element that heat transfer is realized by the phase transformation of therein working fluid, generally by
Shell, liquid-sucking core, working medium composition.Heat pipe package is typically constructed of metal, and both ends are welded with end cap, inner wall of tube shell equipped with one layer by
The tube core (if gravity type heat pipe then without tube core) that porous material is constituted injects certain working medium after vacuumizing in pipe, then close
Envelope.
Heat pipe is the special material with quickly equal temperature characteristics, and hollow metal tube makes it have light feature,

Greatly, the advantages that heat transfer direction is reversible, heat flow density is variable, accommodative ability of environment is relatively strong, drag losses are smaller, so heat pipe-type
Heat exchanger can be compared with the recycling low grade residual heat of limits.
Flue gas waste heat recovery heat exchanger can be divided into air-water heat exchanger, gas-gas heat exchanger by heat transferring medium, and structural shape is logical
Chang Weire cold medium reverse or co-flow in same housing realizes convective heat transfer.Separate type heat pipe exchanger is changed in tradition
In the structure basis of hot device, using the characteristic of the quick samming of heat pipe, using separation design, separating cold fluid and hot fluid makes its difference
Positioned at the upper and lower part of heat exchanger, heat exchanger is finally divided into three evaporator section, adiabatic section and condensation segment parts.
When heat source is when evaporator section is to its heat supply, the heat absorption vaporization of working medium self-heat power becomes steam, effect of the steam in pressure difference
Lower to flow to the other end along intermediate channel high speed, steam is condensed into liquid after condensation segment releases latent heat to cold source；Working medium is being evaporated
When section evaporation, gas-liquid interface is recessed, forms many meniscus, generates capillary pressure, liquid refrigerant is in tube core capillary
The reflux power effect of pressure and gravity etc. is lower to return to evaporator section again, continues heat absorption evaporation, loops back and forth like this, the steaming of working medium
Heat is just constantly transmitted to cold end from hot end by hair and condensation.
Heat exchange of heat pipe separates cold fluid and hot fluid, and centre is usually separated by tube sheet, and heat pipe is suspended on tube sheet, can be used at this
Static seal or welding structure, depending on design needs.Heat exchange of heat pipe is damaged due to, pressure high, compact-sized with heat transfer efficiency
Lose it is small, be conducive to control dew point corrosion the advantages that.
