The Economic Feasibility of Crop Residues as Auxiliary Fuel in Coal‐Fired Power Plants
评估了农作物残渣作为燃煤电厂辅助燃料的经济可行性，基于1975年价格估算残渣的生产、运输和加工成本，并纳入爱荷华州农业规划模型，分析不同能源价格和硫排放约束下残渣替代煤炭的比例。
Abstract Rising fossil fuel costs spark interest in crop residues as a renewable energy source. Residue costs for combustion in power plants are estimated in 1975 prices to evaluate their feasibility. Costs are estimated for farm production, transportation, and processing and handling at the energy recovery level. They are incorporated into an Iowa agricultural programming model which includes an electric utility sector. The model, including crop production, is solved for several scenarios—a base solution, energy price increases, and a sulfur constraint. Under these scenarios, crop residue replaces coal at 20%,40%, and 60% of the 1975 Btu's consumed.
