the successful management in construction costing of wood dry kilns is an advantageous approach which brings us not only the assurance in service profitability but also gives rise customer’s satisfaction. the construction costing of two types of wood dry kilns, namely, prefabricated aluminum-and masonry kilns with normal operation temperature was studied. for this purpose, the construction, dep...

The demand for electricity is currently growing rapidly. In accordance with the government's policy to optimize use of renewable energy sources, including water, by constructing a hydroelectric power plant. study potential utilization Batang river flow aimed at how much optimum electric there in Merangin as hydropower results calculation Kerinci PLTA show that electrical can be generated 366.27...

CO2 capture and storage (CCS) is receiving considerable attention as a potential greenhouse gas (GHG) mitigation option for fossil fuel power plants. Cost and performance estimates for CCS are critical factors in energy and policy analysis. CCS cost studies necessarily employ a host of technical and economic assumptions that can dramatically affect results. Thus, particular studies often are of...

A three-staged least squares translog cost function is estimated for 13 heavy-rail and nine light-rail United States urban mass transit systems for the period 1985-1991. Firm output is taken to be endogenous. Large economies of density are found in operating costs. These economies become even more substantial when the cost of way and structure maintenance and capital costs are incorporated. How...

The fuel cell technology is much better than other alternatives because the equipment„s lifetime costs, including operating costs, are much lower than competing technologies. There are many other benefits that fuel cells provide like low-to-no emissions, lower maintenance costs, high reliability, silent operation, faster fuelling, and constant, high-quality, uninterrupted power. In this paper, ...

The paper contributes to techno-economic modelling of CO2 capture process in coalfired power plants. Technological options of CO2 capture have been chosen and cost estimation relationships (CERs) for the chosen options provided. The CERs are being fitted into a developed overall model of carbon capture and sequestration. Functions relating capital costs, operation and maintenance costs and tota...
