INCREASING THE ENERGY EFFICIENCY OF BOILER AND …

A boiler system audit (see the simplified audit checklist in the Appendix) will likely reveal energy losses and inefficiencies. The objective of good energy management is to minimize them. The payoff can be significant in terms of both savings and emissions. Figure 3 gives a practical hint as to where to direct energy-conservation efforts. . However important the economic, efficient operation
