生活垃圾焚烧发电存在的问题及新技术发展

垃圾焚烧发电是当前国内外有效处理垃圾的最重要途径之一,但垃圾直接焚烧易对环境产生危害。将没经分类处理的城市生活垃圾转化为高热值再生新能源燃料,并建成焚烧高效发电示范生产工程,形成清洁的电能源,烟气净化处理使二英类等烟气排放优于国家标准及欧盟标准的限值要求,其每吨垃圾发电量达约1100k W·h,是国内垃圾焚烧发电厂的2~3倍,实现真正意义上的垃圾"无害化""资源化""效益化""产业化"利用目的。

关于农作物秸秆“焚烧”与“禁烧”的经济问题研究

对农民"焚烧"农作物秸秆与政府"禁烧"农作物秸秆进行博弈分析,结果表明,化解问题的关键是要将农作物秸秆作为资源进行综合开发利用创新,使农民推动秸秆资源转化成经济产品,扩大秸秆资源价值增值空间,获得实际经济利益。为此,应从经济政策上激励创新,发挥政府主导作用和组织化机制上的创新,培育和壮大市场主体;从技术创新支撑对秸秆的利用和发挥循环经济作用等方面建立对策,建立农作物秸秆作为资源进行综合开发利用的长效机制。

Unit Commitment with Production Cost Uncertainty： A Recourse Programming Method

Many studies have considered the solution of Unit Commitment problems for the management of energy networks. In this field, earlier work addressed the problem in determinist cases and in cases dealing with demand uncertainties. In this paper, the authors develop a method to deal with uncertainties related to the cost function. Indeed, such uncertainties often occur in energy networks （waste incinerator with a priori unknown waste amounts, cogeneration plant with uncertainty of the sold electricity price...）. The corresponding optimization problems are large scale stochastic non-linear mixed integer problems. The developed solution method is a recourse based programming one. The main idea is to consider that amounts of energy to produce can be slightly adapted in real time, whereas the on/off statuses of units have to be decided very early in the management procedure. Results show that the proposed approach remains compatible with existing Unit Commitment programming methods and presents an obvious interest with reasonable computing loads.
