Thermal Oil Heater Design: Principles, ZOZEN Solutions, and Competitive Advantages

Part 1: Fundamentals of Thermal Oil Heater Design

Thermal oil heater design is a sophisticated engineering process that balances efficiency, safety, and adaptability to industrial demands. As a closed-loop system, it utilizes organic heat transfer fluids to deliver high-temperature heat with precise control. Below are the core principles of thermal oil heater design:

1. Heat Transfer Efficiency
The design prioritizes maximizing heat exchange through multi-pass tube configurations and optimized flow dynamics.

2.Safety Mechanisms

Pressure and Temperature Controls: Integrated sensors and relief valves prevent overpressure  and overheating, complying with ASME and GB standards.

Leak Prevention: High-grade welded joints ensure system integrity.

3.Energy Recovery Systems
Advanced designs incorporate economizers and etc to recycle flue gas waste heat, boosting high efficiency .

4.Automation and LoT Integration

PLC-based controls enable real-time monitoring and predictive maintenance, reducing boiler downtime.

Part 2: ZOZEN’s Thermal Oil Heater Design Series introduction and Specifications

ZOZEN Boiler, a global leader in industrial heating, offers tailored thermal oil heater design solutions. Below are its flagship models:

1. YQ(Y)W series gas-fired/oil-fired horizontal thermal oil heater

The YQW series oil/gas thermal oil boiler adopts a two or three passes round coil structure. The end of the coil tube is tapered, effectively protecting the end furnace wall of the boiler. It is equipped with advanced combustion equipment, and the operation of the boiler is fully automated. The boiler is shipped as a whole and can be put into operation just by connecting the gas (oil) and electricity after it is in place on the site.

Thermal capacity:1400-14000 kW

Working pressure:0.8-1.0 MPa

Outlet temperature: 320 °C

Available fuel: Natural gas, coke oven gas, biogas, heavy oil, diesel oil, light oil, etc.

Available industries: Petroleum, chemical, chemical fiber, pharmaceutical, textile printing and dyeing, building materials, wood processing, vegetable oil processing and other industries

2. YQ(Y)L series gas-fired/oil-fired thermal oil heater

The YQL series oil/gas thermal oil boiler adopts a two-pass round coil structure. The end of the coil tube is tapered, effectively protecting the end furnace wall of the boiler. It is equipped with advanced combustion equipment, and the operation of the boiler is fully automated. The boiler is shipped as a whole and can be put into operation just by connecting the gas (oil) and electricity after it is in place on the site.

Thermal capacity: 7000-29000 kW

Working pressure: 0.8-1.0 MPa

Outlet temperature: 320 °C

Available fuel: Natural gas, coke oven gas, biogas, heavy oil, diesel oil, light oil, etc.

Available industries: Petroleum, chemical, chemical fiber, pharmaceutical, textile printing and dyeing, building materials, wood processing, vegetable oil processing and other industries

3. YLW series coal-fired thermal oil heater

The YLW series thermal oil heater, with its horizontal layout and square coil tube design, uses a chain grate system for efficient fuel combustion. It incorporates mechanical features for solid fuel feeding, ventilation, and slag removal. During operation, fuel undergoes radiation and convection heat exchanges, proceeds to the waste heat boiler, and subsequently moves to the air preheater and dust remover. The remaining flue gas is then expelled into the atmosphere, resulting in optimal heat transfer and efficient industrial heating.

Thermal capacity:1400-29000 kW

Working pressure:0.8-1.0 MPa

Outlet temperature:320 °C

Available fuel: Bituminous coal, anthracite

Available industries: Chemical, high temperature heating technology for fertilizer, melamine, alumina and so on.

4. YLW series biomass-fired thermal oil heater

The YLW series thermal oil heater, with its horizontal layout and square coil tube design, uses a chain grate system for efficient fuel combustion. It incorporates mechanical features for solid fuel feeding, ventilation, and slag removal. During operation, fuel undergoes radiation and convection heat exchanges, proceeds to the waste heat boiler, and subsequently moves to the air preheater and dust remover. The remaining flue gas is then expelled into the atmosphere, resulting in optimal heat transfer and efficient industrial heating.
