AbstractAbstract
[en] One of the methods for improving of the energy efficiency is the use of a secondary energy resources such as waste products from industrial processes. In case of the oil extraction a great amount of waste product (sunflower shells) with a good thermal potential is available. During the industrial process from 100 kg raw material 15 kg shells are obtained. The combustion heat is about 1700 kJ/kg. The volatile compounds yield is 66.1%. An installation has been constructed intended to use the waste product from the extraction, consisting of: a water tube boiler with a steam capacity of 20 t/h and two PKM-12 type flue boilers and two DKVR 10-13 type water tube boilers. The DKVR 10-13 type boilers are designed for the production of 22.77 kg/s saturated steam with pressure 1.28 MPa and temperature 194oC. They have an unified constructional schemes with a two-drum evaporating system and a natural circulation. The furnace has a horizontally evaporation beam washed by the gas flux. The reconstruction is aimed to create condition for the use of the sunflower shells as a main fuel and the natural gas or other fuel as additional. The scheme is one using the sloping bed combustion. 70% of the steam production is due to the shells combustion. Calculations for the grid parameters have been done. An additional heater improves the efficiency with 4.5% and the expected annual fuel saving is 300 t. The introduction of hot air (165oC) provides both combustion and ecological benefits

AbstractAbstract
[en] Since the implementation of the EEG in Germany the biogas production becomes an independent branch of industry in the agriculture. At this time more than 90 percent of the biogas plants work with co-generation plant for heat and power with a thermal engine efficiencies of more than 50 percent. Because of the location in the rural area heat costumers with a continuous demand of heat over the whole year are rare. This research had a closer look how to use the heat of biogas production efficiently and also generating profit. The aim of the study was to use heat over the whole year, a profitable heat concept without counting the KWK-bonus and an added value on the farm. During the study the following concepts were analyzed: asparagus production using soil heating, drying equipment for different products, the production of fish in aquaculture, the poultry production and the heated production of tomatoes. The results showed different concepts using heat of biogas plants as efficient for farmers. However with only one concept the aims - to use the heat over the whole year, generating a profitable heat concept without counting the KWK-bonus, add an value on the farm - mostly can not be achieved. The combination of different heat concepts is necessary. In this analysis the poultry production in combination with the dryer can be considered as the most efficient concept. Bearing in mind the benefit which can be generated with a heat concept as well as the higher income and the higher technical efficiency of biogas plants operators should implement an individual concept for their heat.

AbstractAbstract
[en] Findings are presented obtained using a model area where the suitability is studied of warming-up free agricultural soil. Improved harvest could be seen, for instance, of strawberries, spinach, raddishes, cabbage, kohlrabi, lentil, maize, autumn rye and barley, potatoes, sugar beet, and soya. Reduced harvest was recorded for some other plants. It was found that hydrothermal and physical properties of the soil had changed, soil acidity had dropped and the phosphorus, potassium and nitrogen contents had decreased. The activity of microorganisms had also decreased. (M.D.)

AbstractAbstract
[en] The agricultural organizations in the South Bohemian Region have suggested the use of low-potential waste heat from the Temelin nuclear power plant in processing feed potatoes, fodder drying, mushroom production, heating greenhouses and agricultural buildings, drying corn and processing vegetables. Greenhouses should be built on an area of 30 hectares. Hydroponics is expected to be used. The location of the greenhouse area relative to the power plant is described. (M.D.). 6 tabs

AbstractAbstract
[en] The proceedings contain 10 papers of which 9 fall under the INIS scope. They all concern the intentions and possibilities of using heat from nuclear power plants, especially from the Temelin power plant. Waste heat will be used for district heating of adjacent conurbations and for agricultural purposes. Various projects are presented using heat from nuclear power plants, such as greenhouse heating, soil heating, cultivation of algae and fish in warmed-up water. The existing experience is described with the use of heat from the Bohunice nuclear power plant. (M.D.). 15 figs., 6 tabs., 17 refs

AbstractAbstract
[en] The efficacy of the disposal of waste heat from nuclear power plants by means of once-through and closed-cycle cooling systems is examined in the context of the physical aspects of water quality standards and guidelines for thermal discharges. Typical thermal standards for each of the four classes of water bodies (rivers, lakes, estuaries, and coastal waters) are identified. Examples of thermal standards established for once-through cooling on open coastal waters are presented. The design and general layout of various types of cooling systems are reviewed. The advantages and disadvantages of each of the cooling systems are presented, with particular emphasis on the discussion of potential environmental impacts. Modeling techniques available for impact assessment are presented. Proper selection and application of the models depend on the availability of site characteristics and understanding of the modeling techniques. Guidelines for choosing an appropriate model are presented. Various methods have been developed for the beneficial use of waste heat largely dissipated to the environment. Examples and associated problems of waste-heat utilization are discussed for agricultural, industrial, aquacultural, and residential uses

AbstractAbstract
[en] The transport of what would otherwise be waste-heat (at temperatures between 30C and 300C) through pipelines using as an energy carrier either methanol or hydrogen gas has been studied.By using numerical models, the relative costs of new kinds of waste-heat transportation systems are evaluated and compared with those using vapor or hot water, which have been the major energy-carriers in pipeline transmission systems until now.Also, environmental regulations and a carbon tax are investigated as incentives for introducing these systems.
