| Abstract: | In this paper, a new kind of reducing temperature and pressure equipment used in the by pass of thermal generating unit has been studied. The design criterion about the axial uniformity of jet flow rates, the calculation methods of through flow capability and the received force of outer baffle plate of collector pipe have been discussed. The stress intensity of outer baffle plate and support plate have been analyzed. An example calculation of this new kind of reducing temperature and pressure equipment used in the second by pass of a 600MW thermal generating unit has been verified. Figs 8, tables 3 and refs 6. |
