Embodiment Construction
[0011] For a clearer understanding of the technical content of the present invention, the following figure 1 As an example to elaborate:
[0012] figure 1 In order to comply with the idea of the present invention, a type of reconstruction plan for isolating the wind system, the object of specific investigation is a 330MW four-corner tangentially fired pulverized coal furnace, which adopts π-shaped layout and staged combustion. The scope of the modified isolated wind system is within the range of the double dotted line. 1 is the isolation air mixer, which can be one or more parallel connection; 2 is the booster fan, which can be one or more parallel connection; 3 is the hot air flow adjustment valve; 4 is the isolation air temperature adjustment valve; Flow regulating valve.
[0013] In this scheme, the isolated air is a mixture of two streams of air, one cold and one hot. The two streams of air are provided by the blower. The cold air is drawn from the front of the air pr...
