unexpectedly fluctuates. Inconsistent gas quality directly translates to product defects, equipment stress, and costly downtime. At the heart of a reliable lies a fundamental principle that eliminates this worry: the Follower-Flow Mixing Principle. We engineer Eaglestar SNG (Synthetic Natural Gas) system around this precise, automated method to deliver gas you can trust, consistently. Let's break down how it works for you.
What Is The Follower-Flow Mixing Principle?
operates on a clear hierarchy. We designate as the Leading Gas – your primary, high-energy fuel source. Air serves as the Follower Gas. The rule is simple: the air flow rate doesn't operate on a fixed setpoint. Instead, it automatically and continuously adjusts itself to precisely match the real-time flow of LPG. This creates a dynamic, locked-in partnership between the two streams, governed by a single target: your preset mixing ratio.
Here is the step-by-step action inside the control panel. First, we meter the instantaneous volumetric flow of your LPG and send this signal to the central PLC. Simultaneously, we measure the air flow, but we don't just take a raw reading. We apply immediate temperature and pressure compensation to this signal, calculating its exact mass flow before sending it to the same PLC. Now, the controller has two live data streams. It continuously compares the actual LPG-vs-Air ratio against your commanded ratio (e.g., 4:6). If the LPG flow changes-because your burner demand changed-the PLC calculates the exact new air flow required in milliseconds. It then sends a command to a high-response pneumatic control valve in the air line, adjusting its opening℃to achieve the new target flow. This measurement-calculation-adjustment cycle runs continuously, hundreds of times per second.
This closed-loop control is what delivers tangible results for your operation. It means the system maintains your specified mixing ratio with a deviation typically within ±0.5%, whether you're at 30% or 100% of your maximum capacity. This precision directly ensures two critical outcomes: consistent heating value of the final mixed gas, and uniform gas composition. Your combustion equipment receives a homogeneous fuel, not a variable mixture. This eliminates hot or cold spots in your process, protects your burner and heat exchangers from thermal stress caused by off-ratio fuel, and guarantees your product receives the same heat treatment every time.
With this principle in action, you move from manual monitoring to automated assurance. Once you set the desired ratio on the control interface, the system assumes responsibility. You no longer need operators to manually adjust valves in response to load changes. The feedback loop handles it. This translates to high operational safety by preventing the formation of an over-rich or over-lean mixture outside safe limits, and to because the system self-corrects continuously. You can focus your attention on your core production outcomes, with the confidence that your fuel supply foundation is stable, precise, and working autonomously to support your process.
