	4.	This model correctly judges the slagging tendency of a kind of coal - water slurry . measurements are taken of the temperature field , flame emissivity , superheater tube wall temperature , exhaust gas temperature and composition 本文介绍了燃油锅炉改烧水煤浆后炉内传热及其污染物的排放测试结果，包括温度场、火焰黑度、过热器管壁温度、排烟温度、排烟成分。
	5.	After thermodynamic calculation on several operation conditions of the furnace , cold - state flow and resistance mensuration , the combustion of the tubular - furnace hearth was changed into swirl and addition of radiate cylinder and oxygen content detection minish 1 . 25 surplus air to less than 1 . 15 , improving the combustion condition and convection and radiate heat transfer efficacy , resuling in reducing the waste - gas temperature 45 , decreasing exhaust gas loss , and saving fuel by 6 % 摘要通过对加热炉几种工况进行热力计算、冷态试验的流场分布及阻力测定和热态试验的炉膛温度场分布及管壁温度等参数的测定，确定将管式加热炉炉膛内直流燃烧改为旋流场燃烧和增加辐射筒，增设烟气含氧量分析，可以将燃烧的过剩空气系数从1 . 35减小到1 . 15以下，极好地改善炉膛内的燃烧状况和对流辐射传热效果，从而降低排烟温度45 ，减少加热炉排烟损失，节约了煤气量6 %以上。
	6.	This article aims at the boiler ' s problems in operation : 1 ) under nominal load , the smoke temperature at the outlet of hearth reaches 1200 , far more exceeds 1050 the original designed temperature . this will always result in slag inside boiler and the temperature of overheater ' s pipe superheat , so that boiler cannot take nominal load and all these influence boiler ' s nomal operation heavily , 2 ) this article also studied the reason why the assistant oil becoming necessary when coal changes . during the nomal operation , many factors ( makeup of combustor and its disposal , smirch and encrust of water wall , excessive air coefficient , temperature of primary air , coal type and density of coal dust ) can deviate the designed working conditions , then affect the boiler ' s nomal operation 本文针对该锅炉在实际运行中存在的问题：在额定负荷下，炉膛出口超温、低温段过热器前烟温高达936 ，远远超过815的设计值；喷燃器四周水冷壁结焦严重，过热器管壁温度超标，无法带上额定负荷；甚至有时因燃煤质量的变化，必须投油助燃的严重情况进行了分析研究。在实际生产过程中，燃烧器的结构、布置，水冷壁的粘污、结垢，过剩空气系数、一次风温、煤种及其浓度变化等许多因素都会偏离锅炉的设计工况，从而影响炉内的传热和燃烧，造成炉膛出口超温、水冷壁结渣等问题。
	7.	There are a lot of advantages when inner trachea applied in air pre - heater , such as the improvement of the temperature of pipe , the low consumption of metal , except for the increment of flow resistance . according to many related papers , it is more proper inner trachea with the structure of short distant between two whorls and shallow depth of whorl . it can enhance heat transfer with smaller flow loss 内螺纹管是一种异形管，和光管相比，管内侧的换热系数大大增强了，应用于空气预热器可以起到提高总传热系数、节约受热面金属消耗量的目的；同时提高了管壁温度，能够减轻低温腐蚀的程度和速度；不足之处是带来了更大的阻力损失。
	8.	Taking some tubular air pre - heater used in one boiler whose capacity is 130 t / h as an example , new blue print with inner trachea is completed by means of computer program . several key design variables may be changed , such as diameter of pipe and velocity of flow of gas . these cases have been considered , and their results have also been compared with each other 比较了几个重要的设计变量，如外管径、烟气流速等参数变化时，总传热系数和空预器本体管子总重量，阻力损失以及最低管壁温度等几个重要设计结果的变化趋势，对内螺纹管空气预热器的设计具有借鉴意义；其间还分析了内螺纹管与光管在设计时的不同之处；最后，初步分析了内螺纹管的优化设计问题，提出了一些建议。
