Research on the Realization of the Maximum Benefit of Thermal Power

Abstract:

First, Anti-balance method is used to build the model of q₂,q₃,q₄ to figure out the Function expression of q₂+q₃+q₄ .when q₂+q₃+q₄ gets the minimum, the corresponded to the excess air ratio is the best excess air ratio. The excess air ratio is related to the load of boiler, so the function image describing the relationship between q₂+q₃+q₄ and excess air ratio under the different load of 192.3MW, 215.8MW, 245.3MW and 298MW are made to get the best excess air ratio. Second, based on the model before, new variables q₅ and q₆ are added to complete the function formula of the efficiency and the excess air ratio, and four function image will be drew to show the tends. Finally, based on the conclusions above, smoke vents oxygen content can take the place of excess air ratio to achieve the purpose of monitoring the boiler in real time.
