Little research which uses life cycle evaluation to investigate the influence of coal on environment directly was found throughout research data at home and abroad. Related research includes those use life cycle evaluation to evaluate the environmental impact of fuels like coal and straw, e.g. ...(论文有官方英文名，LZ自己查好). Punam Singh et. al.[10] of India chose to use life cycle energy analysis (LCEA) to investigate the cooking fuels which is commonly used by Indian family. Material and energy flow during the whole life cyle of cooking fuels are calculated and the energy efficiencies are compared. As a result, biogas was proved to be the best type of cooking fuel for Indian family. Zhu Jinling[11] analyzed corn straw briquette using life cycle evaluation method, ranging from corn growth to final usage as fuel, covering the whole system of corn straw briquette. Consumption and influence on environment of each step of the system was determined. As a result, great improvement was found in aspect of environment compared with conventional fuel. Suggestion was also made to further reduce the environmental load. Since evaluation methods for briquette, binders and desulfurization agents are imperfect according to reference concerning briquette and life cycle evaluation, it's necessary to develop a evaluation system and create corresponding quality standards. In recent years, the idea of life cycle penetrates the evaluation of environmental impact gradually. So we tried to use life cycle evaluation mehtod to evaluate the influence of the whole life cycle of briquette from raw material mining to final usage as fuel on environment. It's not just an improvement in evaluation method and idea, but also an advanced step for perfecting the evaluation system, which provides reliable and scientific support for briquette industrialization and improvement. |
