  • Control Engineering | How do burner combustion control systems work?

    13/1/2015 · They power package boilers, start up larger furnaces with fluidized beds and grates, and heat many other processes. Larger burners have combustion control systems (CCSs) that should be tuned periodically. To understand how to tune gas and/or oil (usually #2 diesel oil) burners, it helps to first understand how and why they work the way they do.Learn More

  • Boiler Fuel - an overview | ScienceDirect Topics

    Fuel flow control. 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 Learn More

  • Fire-tube boiler - Wikipedia

    In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell. The hot gases are directed along a series of fire tubes, or flues, that penetrate the boiler and heat the water thereby generating saturated ("wet") steam.Learn More

  • Steam Boiler: What Is It? How Does It Work? Types Of

    Other methods to control steam temperature are through the use of flue gas circulation, flue gas bypass, or the tilting angle at which the burners fire the furnace. The simplest method for controlling steam temperature is to monitor the temperature of the steam as it exits the boiler and change the position of the spray water valve.Learn More

  • Top Ten Boiler and Combustion Safety Issues to Avoid

    Burning fuel can be useful to mankind as long as it is done as a controlled process. Control means that combustion takes place where we want it, when we want it, and at the rate we want it. Fuel trains are the complicated-looking series of valves, piping, wires, and switches that provide this control.Learn More
