| Abstract: | The paper introduces of the application of the steam temperature variation method in the measurement of gland steam leakage between H.P. and I.P. cylinders of a domestic manufactured 300 MW steam turbine, analyses the effects of the steam leakage on the calculation of the specific heat consumption and the I.P. cylinder's efficiency and suggest that this method be used on turbines of the same type in acceptance tests of new or retrofitted sets, as well as for monitoring the front gland's leakage effect on the H.P. cylinder and the I.P. cylinders front gland behavior and I.P. cylinder's flow passage efficiency during normal speration. |
