Industrial waste heat recovery eight advantages describe a heat transfer efficiency advantages: 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 the heat conductivity of silver 2000 times, 6000 times the purple tube. Thermal speed, high-intensity, high efficiency heat transfer tubes with superconducting temperature difference increases. Since the case gas / water heat exchanger, air-side use of finned tube heat transfer area increases, higher heat transfer efficiency. Heat pipe heat transfer efficiency of the steam generator up to 98%; economizer heat pipe heat transfer efficiency above 90%, economizer efficiency is usually 5% -20% (depending on business equipment availability). Second, the use of advantages: the use of automatic control systems, equipment, automatic replenishment, no special management, safe, reliable, easy to operate, three security advantages: use with pressure and temperature protection, there is no overpressure inside the tube, not afraid dry. After working fluid phase transition, the internal pressure of the heat pipe does not change with temperature changes. For corrosive fumes, you can adjust the evaporator heat transfer area of ??the condenser section 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, the use of heat pipe equipment can solve the low temperature corrosion of boiler problems, further significant reduction in the boiler flue gas temperature, low temperature heat recovery more. Because effectively avoid the dew point corrosion, longer equipment life make four, structural advantages: equipment for straight-through smoke chamber and flue flow cross-section is large, low flue gas velocity, low smoke resistance, flue gas temperature decrease large, low flue gas temperature when entering the water film dust, water vapor generated less, reducing the overall load on the induced draft fan, improve the working conditions of the fan. Flue gas heat recovery equipment can be used continuously. Take place in the form of heat pipe vertical, horizontal flow of flue gas and water to form a reverse air / water heat exchanger, flue gas heat exchanger to maximize efficiency. Fifth, the material advantages: high quality boiler steel, non-polluting, and durable. Phase-change heat pipe vacuum tube, not burn, explode, non-corrosive, non-toxic, corrosion resistant, and are not afraid of leaks, etc., because of the heat pipe work does not need power, no moving parts, no noise. 6, installation advantages: no need for the original boiler or industrial furnace to make changes, without the installation location restrictions, the heat pipe can be installed according to the design needs of any volume tight beat, small footprint, just an ordinary heat exchanger 1/3. Seven Easy maintenance: Each heat pipe heat transfer components are independent, single removable heat pipe replacement, simple and low maintenance costs. Heat pipe with self-shock device so hard fouling, exhaust gas temperature above the dew point control, it is difficult to condensation, coke, corrosion. Flue gas heat exchanger tube is conducive to ash and maintenance. Conversion smoke flue bypass door in the system, when there is a fault, the conversion smoke doors closed, opened bypass flue, flue normal flow, does not affect the normal operation of the boiler. There are many cleaning door for easy maintenance of the equipment. Eight short payback period: 3-8 months recovery of all investments, equipment life more than a decade.
