Thermal oil boiler is a new type of special boiler with low pressure and high precision temperature working characteristics. Thermal oil boiler uses hot oil as heat transfer medium, hot oil circulation pump to make the medium has a forced circulation, then deliver the heat to heating need equipment and then go back to the heating furnace.
It adopts horizontal chamber-fired three-coil pipe structure, the boiler body is composed of an outer coil pipe, a middle coil pipe and an inner coil pipe. Thermal oil boiler can be used for heating in various production process where the heating temperature is between 150℃ and 350℃。

Most factory required the thermic fluid heater, such bitumen, gypsum plant, reaction kettle, Lubricant factory, Printing and dyeing factory, Rubber factory, Lumber factory, Plywood factory, Plastic factory, Food factory, Non-ferrous metal factory, chemical, resines, petrochemical industry, plastic rubber, food factory, oil & fat, paper making, textile, metal -working, plating, construction, lumber, other uses
• Three layer coil tubes, inner coil, middle coil, outer coil
Improving Thermal efficiency of Boiler with 3-coils
Avoid Burning deformation of Boiler Shell at High temperature

• Wet back structure
Use wet back structure; greatly increase the boiler efficiency, and avoid the boiler outside packing burned out for the high temperature
if use dry back, high flue temperature directly heated to the rear smoke box, and the smoke box easy to burnt out

• WE Adopt External Oil Header
1. Prevent flue gas from heating the header directly to Increase the service life
2. Easy maintenance, internal oil header will reduce boiler uselife

Adopt big open door for front smoke box to achieve easy inspection and maintenance
Designed inspection hole in the back, can enter into the boiler furnace for internal inspection by opening the back smoke box door

YYQL vertical thermal oil boiler, for use in factories with limited space;
Skid-mounted thermal oil boilers, require no installation and can be put into operation quickly.

• Oil temperature super alarm
• Low oil flow alarm (pressure difference too large or too small to trigger an alarm)
• Exhaust gas overtemperature
• Liquid level protection
• Automatic burner ignition, flame out, and high/low fire switch.
• System interlock: When the system pressure difference is less than 0.01 MPa or the oil temperature exceeds 320°C, the system automatically interlocks, generates an immediate alarm, and shuts down the combustion engine.
