Controlling the Air-Fuel Ratio in Combustion Furnaces
|Industry||: Machinery (Heat Treatment)|
|Product||: Control and Measurement Station (CX1000/CX2000)|
|The CX1000/CX2000 Measurement and
Control Station has a simple structure and is equipped with temperature and pressure correction functions that help you increase operating efficiencies in combustion furnaces. These functions accurately ascertain quantities used extensively in combustion furnace control such as the air fuel ratio and amount of air supplied to the combustion furnace.
|-||A highly reliable local controller that controls and monitors the air fuel ratio in industrial combustion furnaces|
|-||To raise fuel efficiency by accurately determining gas flow using temperature and pressure correction and precisely controlling the air fuel ratio|
|-||To avoid using external instruments or complicated programming|
|-||To achieve low cost operation into the future by digitally recording control processes and saving the results as quality data, and by reducing maintenance man-hours for the spare parts|
|-||To achieve such CP control and electronic recording in a simple and high cost-performing solution|
The CX comes with PV calculation functions that can perform temperature and pressure corrections without the need for difficult programming by enabling the user to combine calculation functions, enter the needed parameters, and accurately capture the air mass flow. The flow of gas is controlled so that a certain ratio is always maintained relative to the fluctuating air mass flow. The CX1000/CX2000 calculates the air fuel ratio with an SP computation function that maintains a uniform amount of air and gas supplied. The CX improves fuel efficiency by controlling the combustion such that it uses an air fuel ratio based on the precise air mass flow, and contributes to stability in quality and reduction of operating costs.

|CX1000/CX2000 Common Functions for Combustion Furnaces|
|-||With the PV computation function, you can perform temperature and pressure correction of air mass flow with no programming (by combining computation functions).|
|-||Recording of furnace temperature, gas flow, and air mass flow can also be carried out simultaneously.|
|-||The air fuel ratio setting can be changed from the tuning screen.|
|-||Universal input means no need for converters for flow, temperature, and other kinds of input.|
|-||Calculation of amount of flow is also possible with the /M1 option.|
Also, by digitally recording the control process, you can reduce spare parts maintenance cost and operation, allowing for low cost operation into the future.
