Fundamental studies of drying, combustion and ash properties of biomass and impacts of pulp and paper mill operations

加拿大的纸浆和造纸厂米尔斯需要大量的高压蒸汽和电力来运行。约三分之二的所需能量是通过在回收锅炉中燃烧浓缩的黑液（废制浆液）来提供的。其余的来自生物质锅炉，通常被称为猪燃料锅炉，以及当地的公用事业站。生物质锅炉为纸浆和造纸米尔斯厂提供了解决高能源和废物处理成本的手段。为了在全球市场上保持竞争力并满足日益严格的环境法规，米尔斯需要优化操作，以最大限度地提高其生物质锅炉的能量生产，同时最大限度地减少与燃烧相关的环境影响。这项为期4年的合作研究和开发计划旨在获得有关生物质混合物干燥，燃烧和灰分特性的基本数据，并利用这些信息开发可行的控制策略和新技术，以改善生物质锅炉和磨机的操作。这项研究将在该大学进行

Pulp and paper mills in Canada require large amounts of high pressure steam and electric power to operate. About two-thirds of the energy required is supplied by burning the concentrated black liquor (spent pulping liquor) in recovery boilers. The remaining is from biomass boilers, known conventionally as hog-fuel boilers, and from local utility stations. Biomass boilers provide pulp and paper mills with a means of addressing high energy and waste disposal costs. In order to remain competitive on the global market and to meet increasingly stringent environmental regulations, mills need to optimize operations to maximize the energy production of their biomass boilers, while minimizing the environmental impact associated with combustion. This 4-year collaborative research and development program is aimed at obtaining fundamental data on drying, combustion and ash properties of biomass mixtures and to use the information to develop viable control strategies and new technologies to improve biomass boiler and mill operations. The research will be conducted at the University
