Economizers designed for natural gas only, would likely plugup if installed on a coal boiler and would face increased risk of corrosion if installed on an oilfired boiler. some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.

However, the header that forms the inlet or outlet of the component expands with the temperature of the steam or water that it contains. fig. 4 shows the typical motions of the header end and the outermost connecting leg for a superheater or reheater outlet. note that the greatest deflection is when the header temperature is at a maximum.

In pulverized coal fired boiler,the coal is pulverized to a fine powder, so that less than 2 is 300 micro meter and 70 – 75 is below 75 microns. the pulverized coal is blown with part of the combustion air into boiler plant through a series of burner nozzles.
