A rational range of saturation pressure is proposed and a brief introduction of the combustion control system adopted in phase - change heaters is made 研究了介质饱和压力对相变换热加热炉受热面布置的影响，提出了介质饱和压力的合理范围，对相变换热加热炉燃烧控制系统作了简要介绍。
The fuzzy judgment of slagging described in the paper can provide the distribution of slagging on the heated surface and make judgment of the slagging condition on any spot of the furnace wall 本文的结渣模糊判断，能够给出受热面上结渣的分布，对受热面任一部位的结渣情况作出判断。
The cf correlation of some monitored modules and the cf sensitivity to sootblowing are studied and analyzed from the view of the characteristic of heating surface itself and measuring point collocation 针对对象锅炉受热面和测点布置特征，讨论了各监测模块清洁因子的相关性和对吹灰的敏感性。
During operation of coal fueled power plant boiler , heat exchange surfaces will be polluted by soot accumulation . this seriously weakened the heat transfer capability from gas to working fluid 在电站燃煤锅炉的运行过程中，受热面必然会产生积灰污染，这就大大削弱了烟气对工质的传热能力。
Results of calculation show that the influence of different coal quality upon fouling coefficient of the heating surface has comparatively large difference , and affecting more obviously upon the operation performance of boilers 推算结果表明，不同煤质对受热面灰污特性的影响程度相差较大，其对锅炉运行特性的影响比较明显。
Based on practically measured data from several boilers , the real fouling coefficient of different coal quality and of different heating surfaces , as well as real heat transfer coefficient of various heating surfaces have been calculated 摘要根据几台锅炉的实测数据推算不同煤质对不同受热面的实际灰污系数和各种受热面的实际传热系数。
Researches on the engineering example show that the system developed with this model is suitable for various kinds of boiler and any styles of equipment arrangement for the boiler thermodynamic calculation , and has good expansibility 工程使用情况表明，按此模型开发的系统适应多种炉种和任意受热面布置的锅炉热力计算，具备良好可扩充性能。
The combination of the fuzzy judgment of slagging a numerical modeling of combustion process provides the distribution of slagging on the heated surface , all the above methods have not been found in domestic and international publishing 结渣模糊判断与燃烧过程数值模拟相结合，给出受热面上结渣的分布情况，在国内外的文献中，未见有报导。
Based on the assumption of model ' s graphic structure , the object inherit relationships were set up according to the functions of heat exchangers and types of material flows , and the abstract objects including unit and flow were extracted 基于模型为图结构的基本假定，根据受热面功能和物质流种类确定对象之间的继承关系，提取出单元和流一组抽象对象。
For above - mentioned problems , an all - round and systematic induction and collation have been carried out , and concrete preventive measures for applying in to practice being suggested , providing engineering application with reference 对垃圾梦烧中污染物的生成与受热面的腐蚀进行了全面、系统的归纳和整理，并提出了可供实际应用的具体预防措施，可为实际工程应用提供借鉴。
