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.

Boiler Firing Controls Functional Specification • Strategic …

At steady state operation, P is held constant at approximately atmospheric pressure by balancing the resident mass M and the existing temperature T. Furnace temperature in a boiler is not directly controlled and depend on the thermal balance between the heat in (in the burning fuel and heated air) and the heat out (in the flue gas and heat transferred to the pressure parts). The resident mass is automatically balanced by controlling the flue gas flow out of the boiler to maintain a given furnace pressure. When the fuel input is terminated, this balance no longer exists. The flue gas being pulled out f the furnace by the ID fan is now being replaced only by preheated air rather than by the products of combustion in the firing zone. The average temperature of the gases resident in the furnace (or other subsystem) at any given time following fuel trip will decrease rapidly. Because of the temperature drop, the pressure in the furnace …
