Guide for maintenance of boiler unit for thermal power station . part 8 : the maintenance of air preheater 火力发电厂锅炉机组检修导则.第8部分：空气预热器检修
By analyzing the failure cause of boiler air preheater , the measure of preventing it from failure was discussed 摘要通过对锅炉空气预热器失效原因的分析，提出了一些防止空气预热器失效的技术措施。
However , there lies a particular air leakage problem of revolving type air preheater , which will lead to serious energy waste 但是容克式空气预热器有一个独特的漏风问题，空预器漏风会引起严重的能源浪费。
At present , the revolving type air preheater , with its prominent advantage , is the most popular air preheater applied in power station 容克式(回转式)空气预热器是目前大型火电锅炉最流行的空气预热设备，具有很多显著的优势。
In this thesis , several advanced control methods are adopted to improve the performance of the traditional air preheater leakage control system using non - touched sensor 本文采用了多种先进控制方法，用来改进传统的非接触式空气预热器密封间隙控制系统。
It works in the field where the temperature of gas is lowest of all components that be heated in the boiler . in general , air pre - heater is made of smooth pipes 锅炉设备中的低温段管式空气预热器位于锅炉烟气温度比较低的区域，它的管子通常采用光管构成。
It is very important problem how to detect aggregate fuels and sediments temperature on air preheater parts surface effectively in order to prevent air preheater from fire 如何有效地检测空气预热器表面的燃料油污沉积物的温度，是防止空气预热器表面起火所必须考虑的问题。
Heat pipe air pre - heater is adopted to recover gas heat to heat up cold air for burning , reducing flue gas temperature and increasing heat efficiency of injecting steam boiler 采用热管式空气预热器，利用排烟热量加热冷空气，降低了烟气温度，减少排烟热损失，提高注汽炉热效率。
2 . design scheme of gravity heat pipe air pre - heater is proposed which fits the actual situation of injecting steam boilers . detailed heat calculation and design on heat recovery of flue gas is carrying out 提出了采用适合于注汽炉实际工况的重力热管式空气预热器的设计方案，对烟气的余热回收进行了详细的热力计算和设计。
