YY(Q)W series oil/gas-fired thermal oil heater is a new type of industrial heating equipment. It takes fuel oil or natural gas as energy source and thermal oil as heat transfer medium. With circulating oil pump forced liquid-phase circulation, the thermal oil carries heat to production equipment and then returns to the furnace for reheating. It features high temperature output under low working pressure.
This heater can supply multiple temperature levels simultaneously according to customer requirements. It is widely used in petroleum, chemical, textile, printing and dyeing, plastic, food and other industries with stable performance and reliable reputation.
The heater adopts horizontal three-pass structure with compact layout. The heating surface consists of radiant coil and convection coil groups. Fuel burns fully in the combustion chamber. Flue gas transfers heat through radiant zone and convection zone, and is finally discharged through induced draft fan and chimney.
The equipment features high thermal efficiency, complete control system, easy maintenance, energy saving and environmental protection, which is an ideal industrial heating solution.

Performance Characteristics

  1. Adopts advanced intelligent control system to ensure stable medium operation, high thermal efficiency and convenient maintenance.
  2. Full coil heating structure provides sufficient heating area for full heat exchange.
  3. Compact overall structure saves workshop floor space.
  4. Simple installation, only body and combustion chamber assembly required.
  5. Equipped with tail air preheater to recover waste heat and greatly improve overall efficiency.
  6. Integrated automatic detection, intelligent control and interlock alarm system realizes unattended operation and saves labor cost.
  7. High temperature and low pressure operation: heating temperature exceeds 300°C while working pressure is below 1MPa, ensuring high safety.
  8. Optimized furnace size matches flame shape perfectly to achieve high radiant heat transfer efficiency.
  9. Simple system design, no water treatment equipment required, reducing customer investment.
  10. The diameter and length of radiant coils are precisely matched with burner flame to ensure sufficient cooling and stable long-term operation.
