| Abstract: | This article introduces a calculating method to estimate the vibration displacement of boiler structure caused by combustion. The Calculation is based on the power spectral density function of burning pressure field, obtained in home-made 300 MW boilers.A comparison is made between the calculating value and the measuring value of the vibration displacement. The former is in close agreement with the latter, It shows that the calculating data and methed are both reliable. |
