Nowadays in Russia we see rapid modernization of power engineering and transport systems. Under these conditions the issue concerning improvement of regional heat supply system energy-efficiency has gained a new importance. The aim of this study is to find new development directions of the public-private partnership (PPP), specifically from the perspective of its energy efficiency. Amid the financial crisis and economic sanctions the formation of public-private partnership allows increasing of energy efficiency of regional fuel and energy complex by means of regional energy service company creation. This paper will be useful both for central and local government and for private business.

The article describes existing methods of reducing the technological minimum with a quantitative assessment of reducing emissions of pollutants at the CHP using the method of bypass. With the help of specialized program complex the efficiency of the method has been analysed on the example of the power units at Yuzhnaya CHP-22 and CHP-21 JSC “TGC-1” with turbines T-250/300-240 and T-100-130. The article provides guidelines for the range of application of this method as well.

Annotation The development of heat supply schemes is particularly relevant today as according to the Federal Law of Russian Federation of July 27, 2010 No. 190-FZ “About heat supply” after December 31, 2011, the availability of a heat supply scheme is mandatory for settlements and urban districts in Russian Federation. Heat supply schemes are developed in accordance with the Order of the Government of the Russian Federation of February 22, 2012 No. 154 “On requirements for heat supply schemes, the procedure for their development and approval”.

Annotation As a result of the research, additional factors that significantly influenced the reliability of the consumers’ heat supply were assessed, an assessment of the influence of these factors on the reliability of the operation of the heat network was made. The influence of additional factors is taken into account when developing a new methodology and algorithm for calculating the reliability of consumers’ heat supply; a program for calculating the reliability of consumers’ heat supply was developed.

The reheating part of the moisture separator-reheater (MSR) of nuclear power plant (NPP) steam turbine occupies a significant part of MSR volume and requires large consumption of metal. The superheating of low pressure steam provides by the high pressure steam condensation. This steam supplies partly from turbine inlet and partly from turbine stage bleeding because of two superheater stages. The significantly less heat transfer intensity at the single-phase side of reheater comparatively with condensation side requires intensification of heat transfer from the heated-steam. For such goal the different methods can be used: for instance the cross flow of the coiled tubes and finning of straight tubes bundles. Also is perspective the usage of artificial roughness in form of small “moons” and other types of artificial roughnesses.
