The Vertical YQL Gas Oil Fired Thermal Oil Boiler is a high-efficiency industrial heating solution designed for precision and durability. Featuring a wet back internal combustion two-return structure and a top coil tube, this system prevents direct flame radiation on the rear wall, significantly increasing the radiation heating area and maximizing overall thermal efficiency. By utilizing micro-positive pressure operation, the boiler eliminates air leakage in the furnace and flue, ensuring a compact footprint without compromising on combustion intensity.

Engineered for versatility and safety, the YQL series integrates advanced condensation technology to reduce exhaust temperatures and utilizes premium refractory insulation materials to minimize surface heat loss. Equipped with international brand burners and an automated DCS control system, it supports remote management and automatic thermal load adjustment. This makes it an ideal choice for demanding sectors including textile, chemical, rubber, plastics, and food processing industries where consistent thermal oil heating is critical.
