Product Introduction
The Liquid Fuel Delivery System is an engineered solution designed to manage, condition and deliver liquid fuels—including light oil and heavy oil—to combustion equipment with high precision and reliability.
Compared with gaseous fuels, liquid fuels present unique challenges such as inconsistent viscosity, temperature sensitivity, contamination, and vapor accumulation. This system addresses all of these requirements through an integrated platform capable of continuous monitoring, automated adjustment and stable output.
Serving as the fuel preparation and delivery backbone of various industrial heating systems, it ensures that the burner receives fuel at the correct temperature, flow rate, cleanliness, and pressure, enabling combustion stability under demanding operating conditions.
Primary application scenarios include:
Industrial heavy-oil and light-oil burners
Thermal oil heating units
Medium- and high-capacity boilers
Asphalt mixing stations
Process furnaces and industrial kilns
The system is suitable for facilities requiring long-duration operation, tight fuel-control tolerances, and high thermal efficiency.
System Structure
The Liquid Fuel Delivery System is built around a combination of automated mechanisms, thermal-conditioning modules, filtration components and dual-channel circulation loops, creating a robust architecture that supports efficient fuel handling from start to finish.
Two independent liquid-fuel circuits enable alternating or parallel operation. This structure enhances system availability by allowing one circuit to remain operational while the other undergoes inspection, cleaning or repair—ideal for production lines that cannot afford downtime.
The system executes fuel filtration, pressure stabilization, temperature regulation, and safety supervision autonomously. Sensors continuously capture operational data, while built-in logic adjusts pump output and thermal settings to match real-time requirements.
Each subsystem—pumping, heating, filtering or degassing—is assembled as an individual module.
This results in shorter installation timelines, easier expansion, and simplified module-level servicing. Isolation valves allow selective shutdown of modules without affecting the entire fuel supply.
Designed for low-viscosity fuels that require smooth, uninterrupted flow, this subsystem includes:
Self-cleaning filtration unit ensuring debris-free fuel
Pressure-regulated pumping module delivering stable force to the fuel line
Pressure indication and monitoring instruments for quick operational assessment
The design minimizes pulsation, prevents cavitation and ensures reliable atomization at the burner.
Heavy oil requires extensive preprocessing. This subsystem incorporates:
Automatic self-cleaning filtration valve to prevent clogging
Electrically driven pump with pressure control for consistent flow
Reinforced drive housing for high-temperature or high-viscosity environments
Integrated safety and monitoring suite, including a pressure gauge, switchable indicator instruments and a thermometer
Dual-limit thermostats for thermal safety
Degassing and preheating chamber to remove entrapped gases and reduce viscosity for optimal flow characteristics
This configuration guarantees proper fuel atomization, prevents vapor lock, and maintains stable supply even during temperature fluctuations.
Technical Performance
The system supports digital communication protocols, enabling supervisory platforms to read operational values, adjust setpoints and issue commands remotely. Updates in fuel temperature, pump status and pressure feedback can be transmitted to plant control rooms in real time.
The dual-loop design ensures continuous delivery of fuel during routine servicing. Should a sensor indicate abnormal behavior, the system automatically isolates the affected branch while maintaining normal operation in the other circuit.
Fuel characteristics vary significantly between industries and regions. The system’s adaptable design allows engineers to tailor heating capacity, filtration grade, pump output and monitoring intensity according to the project’s process requirements.
The entire process is tightly controlled to maintain fuel consistency:
Fuel intake from storage
Primary and fine filtration to remove mechanical impurities
Pressure stabilization to ensure correct downstream supply
Degassing to prevent vapor-related instability
Preheating and temperature conditioning for improved viscosity and combustion quality
Controlled delivery to the burner under stable pressure and temperature
Continuous monitoring to maintain safe and predictable operation
The result is a combustion-ready fuel stream that supports both efficient heat generation and long-term equipment protection.
