扬水灌区灌溉用水量浅析

通过对运城地区大中型扬水站1984－1999年亩用水量统计分析，提出大中型泵站应综合灌芡产业结构调整和实际灌溉情况，并考虑1997年的旱情，对各站进行规模复核，对有富余供水能力又有发展条件的泵站，建议进行扩大灌区规模设计，以便充分发挥现有工程设施的作用。对规划灌区，要充分考虑农村产业结构调整，及已成灌区亩毛用水量，建议灌溉建设保证率取50％。     

Driving forces and obstacles with regard to co-operation between municipal energy companies and process industries in Sweden

District heating networks can technically enable energy-related co-operations between energy-intensive industries and municipal energy companies. The most common form of co-operation is to utilise industrial waste heat as the primary energy source in district heating networks. However, another type of co-operation is to jointly own a plant that produces both process steam for the industry and hot water for district heating. In this article, eight Swedish energy co-operations are studied and the main focus is on the process leading to co-operations of this kind. Different aspects of factors that facilitate or obstruct the start up and continuous daily operation of a co-operation are discussed. The main conclusion is that while the primary reasons for the foundation of such co-operations are favourable techno-economic factors, this is not enough for a co-operation to emerge. This study highlights the importance of people with a real ambition to co-operate in both parties in the co-operations.     

从5MW THR的环境影响看低温核供热堆的厂址选择

通过分析5MW THR 正常运行和事故工况下放射性释放对环境的影响,说明低温核供热厂址可建造在城市附近,离城市边界的距离为2km,禁区半径为250m。     

Profitability of sparse district heating

The expansion of district heating into areas of low heat densities (heat sparse areas) constitutes a challenge due to the higher distribution costs. The profitability of sparse district heating has been analysed from actual investments in 74 areas with 3227 one-family houses connected to district heating between 2000 and 2004 in Göteborg, Sweden. The profitability was estimated from a probable price model, a typical marginal heat generation cost, and the investments from the actual connections made. The analysis identified factors as the linear heat density and heat sold per house explaining the main variations in profitability. The profitability analysis was concluded with a competition analysis. The main conclusion is that sparse district heating is possible when reaching low investment costs for the local distribution network and low marginal costs for the heat generation. In Sweden, the general competitiveness of sparse district heating is facilitated by the high consumption taxes for fuel oil, natural gas, and electricity. Hence, it should be more difficult to introduce sparse district heating in other countries with low energy taxes.     

Residential energy use and conservation in Sweden

We describe energy use in Swedish homes from 1963 to 1980 using data assembled and analyzed for the first time. Changes in energy use by fuel and purpose before and after the 1973 oil price shock are illustrated and discussed, and savings in space heating in the year 1980, compared with the pre-embargo period, are quantified. We discuss two important elements of Swedish energy conservation policy, the building codes and the system of grants and loans to homeowners. We conclude that the grants and loans probably accelerated home retrofit measures, while the building codes will play an important role in reducing residential heat losses over the long term.
