Design of a Pollution-Free System for the Economic Utilization of Municipal Solid Waste for the City of New York. Task III:Pipeline Transmission versus Gas Turbine Power,

摘要

The report concerns the need to reduce energy costs by examining the most effiecent method of obtaining fuel gas generated from refuse converters in New York City. The most profitable situation exists when a refuse converter installation is located immediately adjacent to a utility boiler. If gas has to be piped over distances through city streets in order to pass to the utility boiler,it becomes quite expensive. An alternative is to burn the compressed gas and expand it though a gas turbine generator so that the energy equivalent may be recovered in the form of electricity and fed directly into the power distribution network. A trade-off study to determine the cost penalty which attaches to gas transmission as a function of distance and the cost of gas turbine generated power as a function of generator capacity is described. Quantitative results of the trade-off calculations are summarized. Costs of gas turbine power generated are compared with costs of gas transmission by pipeline. The appendix gives the characterization of the fuel gas produced by the PUROX Oxygen Refuse Converter system as used in the calculations,the calculation methods,and investment and operating costs.
