The Horizontal/Vertical type YQW/L series represents a pinnacle in thermal energy engineering, specifically designed as a gas or diesel oil fired thermal oil boiler heater. Featuring a sophisticated wet back internal combustion two-return structure, this system is engineered for maximum thermal efficiency and long-term operational stability. By integrating a top coil tube, the design effectively shields the rear wall from direct flame radiation while expanding the heating surface, ensuring an optimized heat transfer process for demanding industrial applications.
Designed for versatility and precision, the YQW/L heater employs micro-positive pressure operation to enhance combustion intensity and eliminate air leakage within the furnace and flue. Coupled with high-efficiency condensation technology and premium refractory insulation, it significantly reduces exhaust gas temperatures and external heat loss. Whether utilized in textile, chemical, rubber, or food processing industries, this boiler provides a scalable, safe, and highly automated heating solution tailored for modern manufacturing needs.
