Fuel Utilization

A comparison of the fuel utilization distribution in power generation for 1 year op­eration for the reference and actual plant data are shown in Fig. 45.5.

The potential fuel savings (i. e. reference—actual) is also shown in Fig. 45.5. This potential savings represent non-capital-intensive potential improvements in operating efficiencies by continuously positioning operational practice towards best practice. The represented potential savings can be gained through effective repair­ing of leaks (natural gas and compressed air); maintaining optimum combustion efficiency, appropriate maintenance practices and optimal strategies for utilizing key equipment, pipes and equipment insulation.

Fig. 45.6 Distribution and comparison of fuel utilization in water desalination for 1 year operation

A comparison of the fuel utilization distribution in water desalination for one year operation for the reference and actual plant data are shown in Fig. 45.6. The potential fuel savings (i. e. reference—actual) are also shown. This potential savings represent non-capital-intensive potential improvements in operating efficiencies by continu­ously positioning operational practice towards best practice. Basic operational prac­tices for gaining the represented potential savings include; retrofits and/or replace­ment of production and auxiliary equipment, upgrades of process-specific equipment such as new waste heat boilers, economizers, and process control instrumentation.

The data analyses presented in the previous paragraphs have examined a co­generation power and water production plant in a bid to explore whether there is potential for improving operating efficiencies and thus reducing fuel utilization. By setting reference performances and comparing them with actual plant operating data, the analysis shows that the case study plant has an annual potential fuel saving of: 93 mmSCF on the water delination side and 5596 mmSCF on the power genera­tion side thus amounting to a total of 5689 mmSCF fuel savings.
