YYQL Vertical Thermal Oil Boiler
YYQL Series Vertical Thermal Oil Boiler is a high-efficiency heat transfer system designed to provide high-temperature thermal oil circulation for industrial heating applications. It adopts diesel, LPG, or natural gas as fuel and uses advanced combustion technology to achieve clean, stable, and efficient operation.
Oil Gas Fired Thermal oil heater boiler, use transfer oil as medium, it is forced circulation oil system, heating oil under specific pressure, adopts horizontal chamber combustion three-coil structure, and its body is composed of outer oil, middle oil, inner oil and rear oil.
Advantages of YYQL Oil Boiler
1. High Temperature & Low Pressure Operation
The boiler uses thermal oil as the heat transfer medium, avoiding high-pressure steam operation. It can achieve high outlet temperatures while maintaining safe and reliable operation.
2. Compact Vertical Design
The vertical structure occupies less space and is suitable for factories with limited installation areas. The integrated design simplifies transportation and installation.
3. High Thermal Efficiency
The optimized furnace structure and heat transfer design improve combustion efficiency, reduce fuel consumption, and lower operating costs.
4. Reliable Safety Performance
The system includes multiple safety protections: High temperature protection, Low oil level protection, Overpressure protection, Flame failure protection, Emergency shutdown function
