The article considers the issue of the influence of air inflow in the vacuum system of a cogeneration steam turbine plant on its energy performance. The authors give a brief description of characteristics of a steam turbine condenser. On the example of the T-110/120 turbine plant, they estimate the power loss factor of a low pressure section (LPS) depending on air inflow in a vacuum system on a heat schedule operating mode with steam consumption of 20 t/h. The authors underline a significant influence of air inflow on the amount of power produced by the turbine plant. Moreover, the authors evaluate the power loss of LPS depending on air inflow in the vacuum system on one of the operation modes on the electrical schedule. They demonstrate that an increase in air inflow leads to quite large (hundreds of kilowatts) power losses.
