[Introduction] Now the coal-fired units have more advantage of bidding to access the net, It also puts forward higher requirements for fine design and optimization of flue gas, air and pulverized coal pipeline in order to achieve the purpose of saving energy and reducing consumption. [Method] The article mainly used the combined research method of theory analysis and practice verification, firstly the function of different flue gas, air and pulverized coal pipeline system are analyzed and discuss theoretically in the view of saving energy and reducing consumption, according to the results of theoretical analysis the article proposed optimization design of the detailed rules for the implementation of different system, the numerical simulation software was used to verify the theoretical results preliminarily, At the same time, the application and practice of the actual project were verified. [Result] The research method of the energy-saving and consumption-reduction scheme proposed for the flue gas, air and pulverized coal pipeline system has been proved theoretically and by practices that it has remarkable energy-saving effect, which can not only reduce the initial investment of the system, but also reduce the annual operation expenditure of the unit. [Conclusion] Although the relevant research results in this paper are based on 1 000 MW units, the basic theories and research methods are commonly applicable to other graded unit projects, which can provide important reference for the design of energy conservation and consumption reduction of flue gas, air and pulverized coal pipeline in subsequent projects.
