Is there anyone who can help draw the interlock logic diagram for the boiler?

Hello, due to limitations of this platform, I am unable to draw the boiler interlock logic diagram for you directly. However, I can describe the basic concepts of the interlock logic for a boiler’s MFT (Main Burner Failure Protection), and you can use this description to draw or design the interlock logic diagram for the boiler. The boiler MFT interlock logic typically includes several protection conditions; the activation of the main burner shutdown protection in the boiler occurs whenever any one of these conditions is met: 1. The exhaust fan stops operating: The exhaust fan is the device responsible for drawing air into the boiler’s combustion system, and its failure to function can affect the normal operation of combustion in the boiler. 2. The forced draft fan stops working: The forced draft fan is used to supply air into the boiler’s combustion chamber to ensure complete combustion of the fuel. The shutdown of the blower will also interrupt the combustion process. 3. Manual MFT: Operators can manually activate the MFT to perform an emergency shutdown of the furnace. 4. Upper limit for drum water level: The drum is the part of the boiler where hot water is stored or steam is generated; if the water level rises too high, exceeding the safety limits, a protective action must be taken to prevent safety issues that could result from such a high level. 5. Low water level limit in the drum: Similarly, if the water level in the drum falls below the safe range, the low water level protection device will be activated to ensure the safe operation of the boiler. 6. Lower furnace pressure limit: An excessively low pressure in the boiler furnace can affect combustion efficiency and even cause issues such as flue gas backflow; therefore, a lower pressure limit protection is necessary. In summary, when drawing a boiler interlock logic diagram, it is necessary to connect the various protection conditions mentioned above using logical relationships (AND, OR, etc.) to create a diagram that illustrates the logical relationships of all protection actions. Typically, such logic diagrams can be represented using ladder diagrams or logic block diagrams, etc., so that operators and maintenance personnel can understand and identify them. The specific design of the interlock logic diagram may need to be based on the actual boiler model, the technical parameters provided by the manufacturer, and safety standards; therefore, an exact interlock logic diagram cannot be provided here. You may consider consulting specific boiler manufacturers or working with engineers specializing in automation and thermal energy to obtain accurate design drawings. .
