Energy efficiency and

Increased energy efficiency. Increasing energy efficiency and the introduction of cogeneration reduce CO2 emissions. Remember that emissions should be viewed on a global basis, as discussed in Chap. 10. 

In order to maintain high energy efficiency and ensure a long service life of the materials of construction in the combustion chamber, turbine and jet nozzle, a clean burning flame must be obtained that minimizes the heat exchange by radiation and limits the formation of carbon deposits. These qualities are determined by two procedures that determine respectively the smoke point and the luminometer index. 

A survey of nonelectrolytic routes for CI2 production was conducted by Argonne National Laboratory the economics of these processes were examined in detail (76). One route identified as energy efficient and economically attractive is the conversion of waste NH Cl to CI2. 

The performance ratio of ME plants is just slightly lower than the number of effects, which is deterrnined as an optimized compromise between energy efficiency and capital cost. Six effects ate typical, although plants with as many as 18 effects have been built. Eurther detail about ME desalination can be found in (56,59). 

Design UF equipment has considerable variety of design, but the trend is toward more compact, energy efficient, and lower-cost designs. Much of the robustness characteristic of older designs is now available in less costly versions. 

Thus the concaster combines in a single process what previously took two separate processes. This is both highly energy-efficient and produces a better quality product. 

Thus, thermal comfort is clearly desirable and important to the well-being and productivity, and thereby the financial health, of industry. An understanding of the principles of thermal comfort and discomfort can help guide a designer s efforts in creating and operating industrial environments that are both energy-efficient and thermally acceptable to the occupants. 

The second kind of modeling is focused on the needs of the planner and HVAC engineer, who has to comply with certain criteria for heat delivery or removal for comfort and energy efficiency and from this has to select a certain type of component available on the market. Once the component is selected, only the performance of this component under variable load is of interest. This kind of modeling normally requires much less input, because actually only the change in performance from a given design point to a point for the actual load has to be determined. 

Each of these products is different each uses a different technology, is subject to different market forces, different production characteristics, distribution practices, and pricing systems. Yet, the dominant trends in energy efficiency, and in the policies used to affect it, show rcniarkablc siniilarity across end uses. 

The benefits of eliminating bottlenecks are twofold energy efficiency and speedier deliveries. In the air freight area, hub-and-spoke systems are very efficient because large carriers such as Federal Express...

The commercial and industrial sectors account for more than fifty percent of all energy consumption in the United States. The Departinent of Commerce (DOC), whose mission is to improve the overall competitiveness of the commercial and industrial sector, is very concerned with reducing consumption through conservation and energy efficiency, and in improving the competitiveness of the energy businesses on the production issues.
