在工矿企业和服务行业中的蒸气锅炉,有相当一部分是五、六十年代的设备,一般均系耗能量大,热效率只为45—55％左右,其排烟温度一般在250—350℃,每年要浪费掉大量的能源。因此,如何提高热效率、降低煤耗,是一项搞好企业经济效益急待解决的重要问题。近年来,对“热管”新技术的研究应用,国内外都非常重视,发展很快,并已开始应用于各个技术领域,特别是节能技术的各个领域。例如,在蒸气锅炉上采用热管新技术,应用“高效换热器“所取得的经济效益就非常显著。现概述如下:
In the industrial and mining enterprises and service industries in the steam boiler, a considerable part of the equipment in the fifties and sixties, are generally Department of energy consumption, thermal efficiency is only 45-55%, the exhaust temperature is generally 250-350 ℃, Every year to waste a lot of energy. Therefore, how to improve thermal efficiency and reduce coal consumption is an important issue to be solved urgently for the economic efficiency of enterprises. In recent years, the research and application of the new technology of “heat pipe” have attached great importance both at home and abroad and have developed rapidly and have been applied to various technical fields, especially in all fields of energy-saving technologies. For example, in the steam boiler using new heat pipe technology, the application of “high-efficiency heat exchanger,” the economic benefits achieved is very significant. Now summarized as follows:
