Boiler Fuel

The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding device (speed variator of coal feeder) directly.

Three-drum boiler

Alfred Yarrow developed his boiler as a response to other water-tube designs, and his perception in 1877 that Yarrow & Co were lagging behind other shipbuilders. His initial thoughts already defined the key features of the design, a three-drum boiler with straight tubes, yet it took ten years of research before the first boiler was supplied for a torpedo boat of 1887.

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also ...
