Environmentally Oriented Modernization of Power Boilers …

The basic way to decrease the impact of a boiler on the environment is to reduce fuel consumption and pollutant emissions. The emissions are identified by means of direct measurements, while fuel consumption depends on the thermal efficiency of the boiler. It

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

The main cause of heat loss in coal-fired boilers are because of the residue of incomplete carbon burnt, dry exhaust gas, condensed vapor in fuel, radiation, and burning of hydrogen atom. The huge part of heat loss usually occures because of high air/ fuel ratios, under rated steam capacity, surface thermal losses, and exhaust gas temperature is too high.
