The paper deals with new construction of low pressure cylinder (LPC) for condensing steam turbines. The flow path of these cylinders is formed on the base of new two-tier stages. As opposed to well known Baumann’s stages newer two-tier stages is a combination of two independent stages with own blades set. Such construction allows to decrease the number of LPC in the existing turbines or to ensure their operation with very high vacuum in the condenser or increases in 1.5 times power capacity of new turbines without increasing of the last stage blade length and LPC number.
