锅炉非设计工况运行
operation of boiler at off-designed conditions
guolu feIShejl gongkLJong yUr、x,119锅炉非设计工况运行(operation of boile:atundesigned eonditions)锅炉在负荷、嫌料特性、给水温度和过量空气系数等偏离设计数据的条件下的运行。实际生产过程中,锅炉经常处于非设计工况下运行。由于上述运行条件的变化,锅炉各部分吸热量、烟气和工质温度、传热情况、减温水量、嫩料量以及锅炉效率(各项热损失)等都要发生相应变化。应认真把握和分析锅炉运行条件的变化,精心调整和采取相应措施。 锅炉负荷变动将引起燃料消耗量、炉内辐射传热盆、对流传热量、锅炉效率相应变化。 燃料消耗t应与负荷相适应,负荷变化不大时,燃料消耗量与负荷基本成正比关系。 炉内辐射传热t随负荷增减而增减。但对应单位工质的辐射换热量随负荷增加而减少,单位燃料量的辐射传热量也减少,炉内温度和炉膛出口烟气温度升高,辐射过热器出口汽温降低。 对流传热t随负荷增减而增减。锅炉负荷增加时,各对流受热面的进出口烟温、温压、传热系数增加,单位工质的对流传热量增加。因此,纯对流过热器出口汽温、省煤器出口水温(或沸腾度)、热风温度均增加。锅炉效率锅炉负荷增加时,嫩料消耗量、烟气量相应增加,炉膛出口烟温和排烟温度升高,排烟热损失增加,炉内温度的升高提高了嫌烧效率,减少了气体和固体不完全燃烧热损失,散热损失也相对减少。 姗料性质变动包括灰分和灰熔融特性、水分、发热t、挥发分的变动,对锅炉影响较复杂。 然料灰分变动灰分增大,对炉内燃烧不利,增加不完全燃烧热损失;单位燃料量中可燃物质含量减少,为保持燕发量不变,必须增加燃料量,增加制粉系统负荷;灰分增大加剧受热面的磨损,灰成分和灰的熔融特性的变化还可能导致固态排渣炉受热面的结渣或液态排渣炉流渣特性的恶化。 燃料水分变动水分增加影响嫩料的着火和燃烧稳定;理论燃烧温度和炉膛出口烟温降低,辐射传热量减少,对流传热量增大,辐射传热与对流传热的比例发生变化;锅炉排烟热损失和不完全燃烧热损失增大,锅炉效率降低,加剧尾部受热面的低温腐蚀和堵灰;此外还对制粉系统干燥出力产生不利影响。 燃料发热t变动主要由燃料中水分和灰分的变化所致,其对锅炉运行的影响与嫩料灰分、水分变动基本相同。 挥发分变动主要对煤粉着火和嫩烧产生影响。挥发分愈低,煤粉愈不易着火,在同样的煤粉细度下,火焰中心位里升高,炉膛出口烟温和过热汽温升高。挥发分过高,可能造成嫩烧器烧损或周围结渣。
