Introduction: reliable heat for modern industry

Hot oil boiler technology and mechanism

Energy movement path in the system:

The main advantage of this system compared to steam boilers:

Heat transfer at high temperatures: Stable operation up to 300°C and in special cases up to 400°C, without the need for high operating pressure (usually 1 to 3 bar).
Extraordinary safety: Due to low pressure operation, the risk of explosion and bursting is greatly reduced. Also, in case of leakage, the thermal oil does not evaporate quickly and causes fewer risks.
Precise temperature control: The ability to accurately adjust the oil output temperature with an accuracy of $\pm 1^{\circ}C$ through the burner controller and temperature sensors.
Higher combustion efficiency: The design of multiple passes (3 passes or 4 passes) of the hot gas path allows for maximum heat absorption and combustion efficiency between 85 and increase by 91%, which leads to a decrease in fuel consumption.

Types of hot oil boilers in power steam

Technical features of hot oil boiler with power steam quality

Advantages of choosing Niro steam to order a hot oil boiler

✅ Guarantee and originality of manufacturing quality

✅ Dedicated and optimized engineering design

Fast and efficient after-sales service

Guarantee after-sales service includes:

✅ Optimum fuel consumption (reduction of operating costs)

Designing a multi-pass path of hot gases (repetition of contact of hot gas with the surface of oil coils) causes maximum heat absorption. In the 4-pass mode, the exhaust gases leave the system with a very low temperature (about 150-180 degrees Celsius), which indicates high efficiency and optimal fuel consumption.

Important points when ordering a hot oil boiler

In order to ensure the purchase of a suitable and efficient product, customers should accurately determine the following information:

1. Exact thermal capacity: Capacity should be defined in terms of kilocalories per hour (Kcal/hr) or megawatts (MW). This capacity should be calculated based on summing up the heat demand of all the consumer equipment (with a suitable reliability factor).
2. Fuel selection: Determining the type of available fuel (natural gas, diesel, diesel fuel or dual fuel) to choose the burner and design the fuel supply system. 3. Space limitations: Providing a detailed plan of the installation site for the optimal design of boiler dimensions (horizontal or vertical). 4. Thermal fluid specifications: Selection of oil type (based on maximum working temperature). If the working temperature is higher than 250°C, oils with a higher boiling point should be used and this should be considered in the design of the boiler. 5. Automation level: Determining the need for a manual control system (with a simple thermostat) or a fully automatic PLC-based system with reporting capabilities.

Specialized production processes in the steam power plant

The manufacturing process of hot oil boilers in steam power is a fully controlled production chain that guarantees the final product with the highest level of quality:

1. Engineering design and simulation: Accurate thermal and structural calculations using specialized software such as Thermoflow for heat exchange optimization and SolidWorks for 3D modeling of the structure.
2. Cutting and forming: Using CNC plasma and laser cutting machines to ensure dimensional accuracy of steel parts and reduce human errors. 3. High quality welding: Implementation of welding according to WPS (Procedure Specification) guidelines by qualified welders (Certified Welders), and regular inspections during the process. 4. Non-Destructive Testing (NDT) and Thermal Operation: Perform UT and RT tests according to required standards, especially on furnace joints and pressurized parts. 5. Insulation and coating: Application of thermal insulation and then the final coating of two-stage epoxy paint resistant to heat and industrial environments. 6. Final assembly and performance test: Installation of burners, pumps, valves and control panel. Finally, perform hydrostatic test (water pressure test) and preheat test (Oil Firing Test) with thermal oil to confirm the overall performance of the system. 7. Final delivery: Complete documentation including installation and operation manual, technical drawings (As-Built Drawing) and warranty card.

Maintenance instructions and key safety tips

Observing the principles of maintenance will dramatically increase the useful life of the hot oil boiler:

Thermal oil: Use only thermal oil that has a high boiling point and thermal stability. Normal industrial oils or water should never be used in the circuit.
Temperature and pressure monitoring: Daily control of the operating temperature and ensuring that the temperature does not exceed the maximum allowable oil temperature.
Filtration: Regular cleaning of the suction and discharge filters of the circulation pump to prevent damage to the pump and reduce the heat exchange capacity.
Charging and oil change: Thermal oil after passing the specified working hours (closed to operating temperature, usually 3 to 5 years) undergoes oxidative degradation. Periodic testing of oil quality (measurement of viscosity and acidity) and its timely replacement is necessary.
Leakage control: Monthly inspection of connections, flanges and pumps to identify possible leaks of hot oil.
