Paper mill waste heat recovery boiler equipment --- heat recovery steam generator HRSG scope of application of this equipment is widely used in the paper industry, textile industry, chemical industry and in the production process using steam as the main production processes of all enterprises. This equipment consists of an external heat exchanger and the connecting pipes and recovery components. II. Heat recovery steam generator equipment operation characteristics of this device without any power, do not consume energy, without special care, no maintenance. Three. Paper mill waste heat recovery boiler equipment --- heat recovery steam generator works of the installation location in the boiler flue, use heat pipe technology for heat recovery. Characteristics of heat pipe heat absorbing efficiency is fast, is a heat transfer element having high conductivity properties, which closed vacuum envelope by the working fluid evaporation and condensation to transfer heat, with a high thermal conductivity, good isothermal, hot and cold sides of the heat transfer area can be arbitrarily changed, long-distance heat, temperature-controlled series of advantages. Hot water generated thermal energy is required for all occasions. Such as: heating, boiler feed water and the production of hot water. IV. Economic According to statistics, a 600 million kcal conducting oil furnace, heat recovery steam generator to use my company can produce more than 1 ton per hour, 6 kg pressure steam generated in the direct economic benefits of over 100 million, the transformation can provide bring huge returns. Fives. After the social use of the device reduces the exhaust gas temperature, exhaust purification necessary; eliminate the pollution of the air, since the full recovery of production materials, eliminating the pollution of the environment. It is expected to achieve good social benefits.
