Question 321Steam Plants - Assistant Engineer

The correct answer is A) biasing. In automatic combustion control systems, increasing or decreasing a loading pressure by a set amount is referred to as "biasing". Biasing involves adjusting the loading pressure, which is the pressure applied to the fuel supply, in order to maintain the desired combustion parameters. This is a key function of automatic combustion control systems. The other answer choices are incorrect because: B) Relaying refers to the transmission of a signal, not the adjustment of loading pressure. C) Loading refers to the actual fuel supply, not the act of adjusting it. D) Transmitting is similar to relaying, referring to the communication of a signal, not the biasing of a pressure.
