Technical And Economic Analysis Of Straw Power Generation Engineering

Since reform and opening up, the rapid socio-economic development and a relative shortage supply of conventional energy formed an irreconcilable contradiction. In order to ensure the rapid development of the national economy, we must adapt to the requirements of the times and find alternative sources of energy or develop renewable energy. Since China's crop stalks is very rich, the annual output of about 700 million tons, over the years has not found the right way to consume straw, resulting in a large number of straw resources are wasted. With scientific and technological development, straw generation become the most promising development of an industry. In recent years, large and small, straw power plants have established throughout the country.This article at first research that there is a lot of crop stalks resources in China , It has indicated that China has the resources advantage to the development of power generation. But some of Straw's own physical characteristics and chemical properties to a collection of straw has brought difficulties. In this paper, by the survey method, the collection of existing Straw power plants economic data, The results showed that the higher cost of straw power generation, power generation costs to 0.52 yuan / Kwh, than thermal power costs (0.35 yuan / Kwh) higher than 0.17 yuan / Kwh. The cost of power generation in a straw, Raw material costs and fixed costs occupy the largest proportion , were 55% and 20%. Another straw power plants under the basic parameters of the impact of its power generation costs of raw materials cost factors, fixed costs, capacity and sensitivity analysis, that raw materials costs, the impact of the straw is sensitive to the cost of power generation, if the declining cost of raw materials 20 percent, power generation costs will drop 0.06 yuan / Kwh; time of the year increased 20 percent, power generation costs fell 0.016 yuan / Kwh. Straw and the cost of power generation for the sensitivity of fixed investment relatively weak. Therefore, in order to reduce the cost of power generation Straw, the need to lower raw material costs and improve straw generating units start with the utilization. This paper straw for the collection process, the collection of straw on the current mode of doing the analysis and research, and the straw transportation, processing, handling, storage and other areas were analyzed, and the establishment of the compression and transportation of mathematical models to find a straw Does not require compression and direct transportation than the economy's largest collection of a radius of 10 Km. Through the different raw materials stored for a comparative analysis of the use of modern concept of automated warehouses for the storage of straw design, completed a straw from the fields to plant the entire collection process logistics design.
