1, high heat transfer efficiency: absorb and release heat pipe is vaporized potential, as well as the working fluid flow to the conduction of heat by the working fluid phase transition, high thermal conductivity, heat capacity is equivalent to 2,000 times the heat conductivity of silver, purple tube 6,000 times. 2, isotherm performance: heat pipe cavity under pressure saturated steam flow from the evaporator condenser section of the difference is very small, and thus the entire heat pipe temperature difference is small (only 1 ° C) or so). Heat pipe work to a higher wall temperature, away from the acid dew point and low temperature corrosion area, avoiding corrosion and condensation phenomena will appear fundamentally significant reduction in maintenance costs of equipment, does not require frequent cleaning, and easy cleaning. 3, the flow resistance is small: Due to the compact design of the structure economizer heat pipe, heat is flexible, and small size, light weight, small footprint, only 300PA about smoke damage, making it ideal for all types of boiler flue gas heat recovery use . 4, safe and reliable: As the heat pipe work does not need power, no moving parts, no noise, both hot and cold fluid flow in the outer tube and completely separated by partitions, a single heat pipe work independently of each other, flammable, explosive, corrosive, dusty places such as heat transfer fluid with high security and reliability, long life, which is the heat pipe can be used in the main space of five wall temperature adjustable control: For less corrosive strong smoke, you can adjust the evaporator, condenser section of the heat transfer area to control the heat pipe wall temperature, so as to avoid the maximum heat pipe corrosion area, away from the flue gas acid dew corrosion, so use economizer heat pipe can be completely Boiler low temperature corrosion problem solving, further significant reduction in the boiler flue gas temperature, low temperature heat recovery more. Boiler economizer heat pipe economizer performance comparison with the ordinary one, volume and external style more common economizer: size, weight, and because the connection flange and more prone to leaking air leakage, heat pipe boiler economizer: Volume Small, light weight suction flange connected to a small number. 2, the thermal efficiency is relatively common economizer: isothermal poor thermal slow, low-intensity, low-heat pipe thermal efficiency of the boiler economizer: isothermal high, thermal speed up the speed of sound. 3, to provide more general efficiency economizers: heat transfer efficiency of 10% -20%, coal saving efficiency is relatively low, generally 2% -5%; heat pipe boiler economizers: heat transfer efficiency of 35% -50% economizer efficiency is relatively low, usually in 3% -16% (depending on business equipment availability), economizer effect is more obvious. 4, decontamination and corrosion resistance of the more common economizer: because smoke away from the inner tube heat conduction from the wall, a long time easy to fouling corrosion; heat pipe boiler economizer: Because it is difficult to plot from the shock device ash, flue gas temperature above the dew point control, it is difficult to condensation, coke, corrosion. 5, the service life of more general economizer: life is short, usually 2-5 years in the boiler economizer heat pipe: long life, generally more than 10 years.
