  • Energy conservation during treatment of sewage from populated area

    At present an important role in solving energy conservation problem is assigned to thermal pumping plants (TPP). Using processes of evaporation and condensation of easily boiling liquid circulating in the system they extract low potential heat from environmental objects and provide heat supply for buildings, constructions, greenhousee and so on. Artificial sources of low potential heat for TPP of different capacity can be, for instance, ventilation air and exhaust gases, circulating and waste water,ground. Energy efficient reasonability of TPP use in the system of water disposal for the town of Novocherkassk in Rostov region is considered. Calculations indicate that there is a technical potential to replace a boiler house operating on expensive gas fuel and emissing into the atmospere more than 850 t of carbon dioxide - greenhouse gas - with ecologically clean TPP, one of which uses heat of waste water and the other - heat of ground.

      Prospects are discussed of interorbital transportation vehicles based on reusable space tugs with nuclear electric rocket propulsion for spacecraft delivering to the high orbits. The potential advantages of this kind of tugs are demonstrated comparing with the traditional spacecraft launch technologies. The issues of the nuclear interorbital tugs development are examined with the special attention towards the baseline information uncertainty, as well as of the nuclear space tugs ground processing considering requirements of the nuclear and radiation safety.

    Keywords: Geostationary orbit, spacecraft, interorbital space tug, parametric optimization, radiation safety, upper stage, interorbital transportation means, nuclear electric rocket propulsion, power and propulsion system.
