      按照《中华人民共和国大气污染防治法》、西安市《汽锅大气污染物排放尺度》(DB11/139-2015)的划定,自2017年4月1日起,对燃气汽锅排放浓度跨越80毫克/立方米的单元单子应处10—100万罚款,情节严重的,责令休业、封闭。2017是“清煤降氮”的枢纽之年,本年越来越多的企业插足到汽锅革新的大潮中,那么汽锅低氮燃烧器革新的注重事项有哪些呢?

According to the law of the People's Republic of China on the prevention and control of atmospheric pollution, Beijing "boiler air pollutant emission standard" (DB11/139-2015), since April 1, 2017, the concentration of gas boiler emissions more than 80 mg/cubic meter of the unit should be about 10, 1 million fine, if the circumstances are serious, shall be ordered to shut, shut down. 2017 is the key year of "clean coal and reduce nitrogen". This year more and more enterprises are joining the trend of boiler reform.

1)汽锅低氮燃烧器革新留意事项一:调试之前的查抄

查看低氮燃烧器的燃气是否到位,燃气管路的是否清洁通行,阀门是否已开启。低氮燃烧器有无管路泄露现象,管道安装是否合理。从燃气阀前管道放气排空,以确保管路中无夹杂空气,同时排空管应接出室外。

Check whether the gas of the low nitrogen burner is in place, whether the gas pipeline is clean and free, and whether the valve has been opened. Low nitrogen burners with or without pipeline leakage, pipeline installation is reasonable. Drain air from the pipe in front of the gas valve to ensure that there is no mixed air in the pipeline and the drain pipe should be outside.

2)汽锅低氮燃烧器革新留意事项二:燃烧不乱和燃烧的动态均衡

Attention to the reform of boiler low nitrogen burner two: combustion stability and dynamic balance

切记燃烧调整是低氮燃烧器一切调整的根蒂,对于汽温来说燃烧更是素质,岂论在任何工况转变下只要包管燃烧不变和燃烧的动态均衡,因为汽温是烟气发烧量与蒸汽吸热量相均衡的标记,只要能维持这个动态均衡,汽温就能连结不变。

Remember that combustion adjustment is the basis of all low nitrogen burner adjustment, combustion is essential for steam temperature, under any condition change, no matter as long as the guarantee stability and combustion of dynamic balance, because the steam temperature is a sign of flue gas heat and steam heat absorption phase equilibrium, as long as you can to maintain the dynamic balance, steam temperature can remain stable.

3)汽锅低氮燃烧器革新注重事项三:汽锅的火焰中心

汽锅火焰中心的凹凸也是影响汽温凹凸的主要身分,在运行中汽温高时可减小上排燃烧器煤量增加下排燃烧器煤量,反之亦然。低氮燃烧器在运行中还要注重磨煤机分歧组合体例运行对汽温的影响,下排组合烟温水平低汽温调节裕度大,而上排组合烟温水平高造成汽温调节裕度小易超温,要凭据情形实时增强吹灰和注重调整配风。

The height of the boiler flame center is also an important factor influencing the temperature of steam. When the temperature of steam is high, the amount of coal in the upper exhauster can be reduced and the amount of coal in the lower burner can be increased, and vice versa. Also note in the operation of the low nitrogen burner in coal mill run different combinations of the influence of steam temperature, discharge low level of combined smoke temperature steam temperature regulation margin, and combination on the smoke temperature caused high steam temperature regulating margin small yi chao wen, according to the situation in a timely manner to strengthen blowing and pay attention to adjust the air distribution.

因为汽锅低氮燃烧器在市场上运营革新的时间短,对问题的熟悉还不充裕,对处理问题的经验还不足,为缓解燃煤发电厂的环保压力,降低氮的减排手艺还需进一步研究和成长,选择值得相信的低氮燃烧器尤其主要。更为主要的是在新的减排手艺和环保举措应用后发生的问题处理能力要进一步晋升,为燃煤发电厂的可持续成长争夺更大的环保效益。

Nitrogen burner on the market because of the low boiler operating time is short of, understanding of the problem is not enough, but not enough experience to deal with problems, coal-fired power plants to alleviate environmental pressure, reduce nitrogen emissions technology still need further research and development, choose low nitrogen burner that is worth of trust is particularly important. More importantly, after the application of new emission reduction technologies and environmental protection facilities, the capacity to deal with problems will be further improved, so as to achieve greater environmental benefits for the sustainable development of coal-fired power plants.
