纵观锅炉业，气势恢宏，无论是工业锅炉还是电站锅炉，都要具备安全性和可靠性这两大核心，而这两个核心点都离不开空气预热器，空气预热器的低温腐蚀、堵灰和磨损特点正是锅炉所需要的，搪瓷管空气预热器对解决这些问题有良好的方法，既抗磨，又耐腐蚀，结构简单，使用寿命长。
Throughout the industry boiler, magnificent, whether industrial boiler and power plant boiler, with safety and reliability of the two big core, and the two core points are inseparable from the air preheater, low-temperature corrosion of air preheater and ash clogging and wear characteristics is needed by the boiler, the enamel pipe air preheater to solve these problems have good method, both wear resistance and corrosion resistance, simple structure, long service life.
换热器的换热管是一种特殊的搪瓷钢管，它的管子是连接在管板上的，能同时强化管内、管外气流与管壁的对流换热，这就大大提高了预热器的传热系数。搪瓷管空气预热器是锅炉尾部烟道中的烟气通过内部的散热片，将进入锅炉前的空气预热到一定温度的受热面，用于提高锅炉的热交换性能，降低能量消耗。
For heat exchanger of heat exchange tube is a special kind of enamel steel tube, the tube is connected on the tube plate, can also strengthen the inner tube and tube convection of air and tube wall heat transfer, which greatly improves the preheater heat transfer coefficient. Enamel tube air preheater is a flue at the tail of the boiler flue gas through the internal heatsink, will enter boiler air preheating to a certain temperature of heating surface, used to improve the boiler heat exchange performance, reduce energy consumption.
传统的空气预热器的磨损集中在烟气进口处，由于烟气在进入预热器换热管后会形成烟气涡流，涡流携带粉尘固体物磨擦管壁，长此以往，管壁被磨穿就会漏风。另外一个问题是低温腐蚀，当预热器排烟温度较低时，就会形成露点，产生硫腐蚀，硫腐蚀的产生会造成预热器漏风、积灰堵塞。
Traditional air preheater wear concentrates on the flue gas inlet, because the smoke into the preheater heat exchange tube will form flue gas eddy, eddy current carrying friction dust solid wall tube, continuously for a long time, the pipe wall is worn out will leak out. Another problem is the low temperature corrosion, when the preheater exhaust temperature is low, it will form a dew point, produce sulfur corrosion, sulfur corrosion produced will cause preheater air leakage, ash blockage.
