Combustion Controls for Boilers | Liming | Process Heating

Figure 3 Boiler Master Control COMBUSTION CONTROL The primary function of combustion control is to deliver air and fuel to the burner at a rate that satisfies the firing rate demand and with a mixture (air/fuel ratio) that provides safe and efficient combustion. Insufficient air flow wastes fuel due to incomplete combustion, and it can cause an

2. Measurement and Control Principles for a Boiler Combustion system Figure 1 shows the process for combustion system of boiler. Steam is produced by a drum, which is heated by means of water wall around the inside of furnace. As for the control schemes, three control loops are installed for the fuel, the airflow and the furnace negative

A combustion control system capable of accepting rapid load changes is shown in Figure . Two control elements are used, 'steam flow' and 'steam pressure'. The steam pressure signal is fed to a two-term controller and is compared with the desired value. Any deviation results in a signal to the summing relay.

air inputs. The system recorrects combustion air flow using steam flow as a setpoint for air flow, since steam flow is a function of fuel Btu input (inferred fuel flow). This system relates directly to a series parallel type control with the addition of a feed forward signal from the steam pressure controller to the combustion air control.
