Research on Energy-saving and Efficiency-increasing Reformation of Circulating Fluidized bed Boiler

Guang Qi

[Abstract]With the establishment of my country's green and low-carbon circular development economic system and the implementation of energy saving and environmental protection policies， circulating fluidized bed boilers， as a clean coal combustion technology with high efficiency and low pollution， have gradually begun to be widely used by enterprises in the industry Attention and use. However， after research and investigation， it is found that there are still various problems in large-scale circulating fluidized bed boilers. Based on this， this article first analyzes the functions and characteristics of circulating fluidized bed boilers， and expounds the current status and existing problems of circulating fluidized bed boilers. Problems， and pointed out opinions and suggestions on the research of energy-saving and efficiency-enhancing reformation of circulating fluidized bed boilers.

1 循环流化床锅炉的功能和特点分析

1.1 燃烧效率高且适应性强

循环流化床锅炉中有大量灰粒子，因此其具有较稳定的循环性。由于循环流化床锅炉具备较强的流动性，因此能够实现热量与质量充分交换，同时也为燃料预热和引燃创造了良好的前提环境，并且对于部分没有燃尽的煤炭也可以通过延长其在锅炉内的储存时间来进行多次循环燃烧，反复参与多次的热量和质量交换，一直到煤炭被充分燃尽为止，如此操作方式和储存方式也大大提高了燃料的利用效率。……
