Wind power systems for heat supply of settlements: Heat supply development strategy

The strategic aim for thermal systems development is reliable, qualitative and secure heat supply to all branches of economics and social sphere of the country on the base of their technological reconstruction using combined method for thermal and electrical power production     more...

Wind power systems for heat supply of settlements: Economical drivers of thermal power market

Heat supply is one of the most energy expensive branches of economy. Systems of centralized heat supply provide thermal power to multistorey apartment houses, communal and industrial objects and to individual houses (dwellings), located in the regions     more...

Wind power systems for heat production, storage and supply of settlements, industrial and agro-industrial objects

This paper covers a subject, which during the past ten years has undergone an explosive growth. Until now the most common schemes employed for heat power production and supply the traditional heat only boilers on the organics fossil fuel are used. The existent systems for heat supply of settlements have the next restrictions     more...

Damless hydropower technologies and equipments on the basis of semi-submerged and submerged hydro-turbines: Conclusions

The main negative factor limiting the development of large dammed hydroelectric power plants is a violation of the ecological balance of the environment, linked with the necessity to build large dams and create large reservoirs. Large territories suitable     more...

Damless hydropower technologies and equipments on the basis of semi-submerged and submerged hydro-turbines: The dynamics of costs

A high capital cost is the biggest barrier in the way to a broad development of small hydropower. Capital expenditures include the development of the project, construction of     more...

Cascaded damless hydropower plants with submerged hydro turbines

To increase total power the hydro turbines are installed within the river in a few rows (cascades). In this case, the total power of cascaded hydroelectric plant is determined as the sum of electric powers of individual components. Figure 2.24 shows a schematic view of cascaded hydroelectric power plant with submerged hydroturbines.     more...
