Significant fuel safety can be reached due to application of intermediate superheating. For condensing installation the inner absolute efficiency is defined from the relation:

hi = Hi/q0

where Нi is work, performed by 1 kg of steam in the wheel space, kJ/kg; q0 is a volume of heat, supplied to the working substance, kJ/kg.
