Potential Saving For Steam Boilers Based On The Impact Of Most Affecting Factors: A Case Study

This paper presents valuable potential savings from fuel and financial expenses of a steam boiler being studied at Elkhmus power plant, Libya. For this research, a visual basic program was developed and being applied for analyzing the gathered data. Key findings pointed to an acceptable level of savings throughout the entire operations within the studied section of the power plant. The highest level of findings was found to be the increasing of thermal gain along with the total efficiency of the boiler as a result of using the exhaust temperature for heating-up the feed water to the boiler. It was clearly found that the increase of the total efficiency has a direct impact on saving the amount of consumed fuel, and thereby the financial expenses were saved by an average of about 11.6% arabic 16 English 78

Effects of Finny-shaped Absorber Surface on Basin-solar Still Behavior

Abstract For this study, two identical single-effect of single basin solar stills are designed, fabricated, tested, and evaluated, where one of them is employed alone which is referred to as “passive still”, while the other is coupled to a flat plate solar collector introducing what so called the active still. Both are installed at the same site in Tripoli-Libya and they are oriented due to south. Measurement of various temperatures, solar intensities, humidity, wind speed and distillated water production are taken each hour for several days of August under various operating conditions. Two operational modes are considered; each of the passive and active stills is operating for the whole day. These tests were performed using seawater and water basin different depths. The water production of the active still is reported to be 6.6 L/m2.day which is higher than that of the passive still by 56 per cent approximately. The maximum daily efficiency is calculated to be 24 per cent approximately for the active still system while it is 14 per cent approximately for the passive still. Yet, the still thermal performance seems to have a complex function of geometrical, constructional, and operational conditions, site characteristics and layout details.

Just-In-Time for Reducing Inventory Costs throughout a Supply Chain: A Case Study

Supply Chain Management (SCM) is the integration between manufacturer, transporter and customer in order to form one seamless chain that allows smooth flow of raw materials, information and products throughout the entire network that help in minimizing all related efforts and costs. The main objective of this paper is to develop a model that can accept a specified number of spare-parts within the supply chain, simulating its inventory operations throughout all stages in order to minimize the inventory holding costs, base-stock, safety-stock, and to find the optimum quantity of inventory levels, thereby suggesting a way forward to adapt some factors of Just-In-Time to minimizing the inventory costs throughout the entire supply chain. The model has been developed using Micro- Soft Excel & Visual Basic in order to study inventory allocations in any network of the supply chain. The application and reproducibility of this model were tested by comparing the actual system that was implemented in the case study with the results of the developed model. The findings showed that the total inventory costs of the developed model are about 50% less than the actual costs of the inventory items within the case study. arabic 14 English 67
