Coal Fired Boiler Cases

In this article, we look at the construction and operation of the marine boilers found on both steam-powered and fuel oil powered ships. The steam generation process is explained and important key phrases are defined. The various uses for steam aboard ship are described, and the difference between the water tube and fire tube basic designs in explained.

Auxiliary boiler is a power production boiler, It produce power for initiate the process of main production boiler. The Main power production boiler taking too much of power (Pumping the water, Initial firing, Milling / Pulverise the Coal & ID,FD

As coal-fired and biomass boilers require many pieces of auxiliary equipment, the application of a DCS has realized significantly reduced operator loads. An example of the implementation of an integrated control system for a power generation facility is shown in Figure 1.
