立式蒸汽锅炉抑制有毒气体

小易为你介绍一下立式蒸汽锅炉抑制有毒气体

我国几乎所有都在进行大规模的煤制天然气运输。 立式蒸汽锅炉的使用大大减少了微粒的染色,并且还抑制了诸如氮氧化物的有毒气体的排放。 效率是垂直蒸汽锅炉的关键指标,也是垂直蒸汽锅炉效率的根本原因。 经有关部门调查后,立式蒸汽锅炉的热量损失可能由两部分组成:空气燃烧超理想,烟气的热量损失排出。 减少烟气排放的热量损失可以通过在立式蒸汽锅炉末端进行废气再加热,或使用更先进的冷凝锅炉进行改造。

 
  空气燃烧非常理想。 用于一般立式蒸汽锅炉的喷射器燃烧器使得不可能操纵空燃比。 大量立式蒸汽锅炉使用非自动供气燃烧器,这导致空燃比不令人满意。 空气源比率不理想。 有两种情况:如果有过量的氧气,就会有无限多余的冷空气。 加热时,会增加立式蒸汽锅炉的运行成本,而立式蒸汽锅炉效率低下; 当氧气不足时,焚烧不充分,垂直蒸汽锅炉效率低下。
 
  如何调整蒸汽锅炉设备的蒸汽负荷?
 

  主要是改变燃料立方体来改变蒸汽负荷。 增加燃料,蒸汽锅炉设备增加了热量储存,产生更大比例的蒸汽,从而增加了负荷,减少燃料将减少蒸汽负荷。

Xiaoyi introduces to you the suppression of poisonous gases in vertical steam boilers

Almost all of China is carrying out large-scale transportation of coal-based natural gas. The use of vertical steam boilers greatly reduces the dyeing of particulates and also inhibits the emission of toxic gases such as nitrogen oxides. Efficiency is the key index of vertical steam boilers, and also the fundamental reason for the efficiency of vertical steam boilers. After investigation by relevant departments, the heat loss of vertical steam boilers may consist of two parts: super ideal air combustion and exhaust heat loss of flue gas. Reducing heat loss from flue gas emissions can be achieved through waste gas reheating at the end of vertical steam boilers, or by retrofitting with more advanced condensing boilers.



Air combustion is ideal. The ejector burner used in general vertical steam boilers makes it impossible to control the air-fuel ratio. A large number of vertical steam boilers use non-automatic gas supply burners, which results in unsatisfactory air-fuel ratio. The air source ratio is not ideal. There are two situations: if there is excessive oxygen, there will be unlimited excess cold air. When heated, the operation cost of vertical steam boilers will increase, while the efficiency of vertical steam boilers is low; when oxygen is insufficient, incineration is insufficient, and the efficiency of vertical steam boilers is low.



How to adjust the steam load of steam boiler equipment?



The main purpose is to change the fuel cube to change the steam load. Increase fuel, steam boiler equipment increases heat storage, producing a larger proportion of steam, thereby increasing load, reducing fuel will reduce steam load.
