锅炉排污水的回收利用

锅炉在运行中,由于锅水不断地蒸发、浓缩,锅水中的含盐量不断增加。同时,锅筒底部的炉水所含的泥渣、水垢等沉积物的浓度也越来越高．通过定期或连续排污,可使锅筒内的泥渣等沉积物随炉水排出炉外,防止锅筒中集。结水垢,影响锅炉的水循环和传热效率,从而保证锅炉安全,平稳经济的运行。 但是,排污水中除含有少量的水垢、泥沙等沉积物以外,绝大部分是含有大量热量的软化水。这部分水的排放,会造成热量和水的浪费,从而使吨蒸汽的费用升高,用汽量增加．因此,回收利用这部分排污水,可大大降低吨蒸汽的消耗费用。 我们对ＳＨＬ６．…

ENERGY REQUIREMENTS AND WAYS OF SAVING ENERGY IN THE PRODUCTION PROCESS OF PHOTOVOLTAIC MODULES

The results of an investigation of energy requirements and ways of saving energy in the production process of photovoltaic modules are reported. The investigation was carried out as a process chain analysis. It contains a comprehensive collection of process step data, from the reduction of SiO₂ up to the completed module. Analysis and comparison results include conventional mono- and multicrystalline silicon modules as well as MIS-I modules and thin film solar cells based on amorphous silicon. The investigation includes model cases of an expanded production volume and its implications for energy requirements.

Modifications of the production process in pursuit of the goal of improved cell efficiency need to be reviewed taking into account the accumulated energy requirements of the whole module. The data framework presented in the report provides a reliable, fast and flexible measure that enables researchers to meet this condition.

THE IMPLICATIONS OF ENERGY AND OTHER INPUT USE FOR CONSERVATION TILLAGE

An important issue with regard to the overall effectiveness of conservation tillage practices in reducing the impact of agricultural production on the environment concerns what happens to energy, pesticide and fertilizer use as these practices are more extensively adopted. To gain some insight into this, the conservation tillage adoption decision is modelled. Starting with the assumption that the conservation tillage adoption decision is a two step procedure — the first is the decision whether or not to adopt a conservation tillage production system and the second is the decision on the extent to which conservation tillage should be used — appropriate models of the Cragg and Heckman (dominance) type are estimated. Based on farm-level data on corn production in the United States for 1987, the profile of a farm on which conservation tillage was adopted is that the cropland had above average slope and experienced above average rainfall, the farm was a cash grain enterprise, and had an above average expenditure on pesticides, a below average expenditure on energy and a below average expenditure on custom pesticide applications. Additionally, for a farm adopting a no-tillage production practice, an above average expenditure was made on fertilizer. © 1997 by John Wiley and Sons, Ltd., Int. J.
