YGL series vertical type thermal oil heater is a safe and energy-saving boiler featuring low working pressure (0.8 MPa) and high operating temperature up to 350℃. Heat conduction oil is used as the heat carrier. Driven by a circulating pump, the thermal oil flows in liquid phase to transfer heat to user equipment, then returns to the furnace for reheating. It adopts a vertical structure with moving grate combustion, supporting manual or mechanical fuel feeding. Suitable fuels include coal and biomass such as wood, bagasse, straw, peanut shell, and rice husk.
Features:
1. Compatible with various fuels such as bituminous coal, lean coal, and anthracite.
2. Thermal efficiency 5–15% higher than typical boilers, saving up to USD 70,000 annually for a 10 tph unit.
3. Custom feeding, slag discharge, and flue gas systems save time and cost.
4. Easy fuel feeding and ash removal with high automation and low manpower needs.
5. Advanced interlock control system ensures safe operation.


With high operating temperature, low pressure, and energy-saving performance, thermal oil heaters are widely used across industrial sectors, including:
Textile: Dyeing, drying, resin setting, high-temperature machines
Food: Cooking, drying, oil refining
Chemical: Reaction tanks, distillation, concentration
Plastics: Heating and extrusion
Rubber: Pressing, vulcanization, molding
Paper: Drying, corrugated processing, calendering
Wood: Hot processing and setting
Machinery: Drying and assembly
Building materials: Plasterboard drying, asphalt heating, component curing
