Heat transfer oil furnace

Oil and gas fired thermal oil furnace is a type of thermal oil furnace using FO, DO or LPG, CNG, and Biogas as fuel.

Features and characteristics

Thermal oil systems provide an efficient source for processes requiring high temperatures up to 300 ° C.
 Operating costs are generally less expensive than steam systems and often require less maintenance.
 Thermal oil furnace systems are more thermally efficient and do not lose heat to the atmosphere through steam traps and leaks as in steam systems.
 It is also important to reduce the cost of the heat transfer furnace with a very simple design and operation.
 Thermal oil systems are safer than steam systems because the system operates under low pressure (just the pressure of the pump to overcome the resistance to circulating the heat oil in the system).

Product Description

The thermal oil system provides an efficient source for processes that require high temperatures up to 300 °C

 Operating costs are generally less expensive than steam systems and often require less maintenance.

 Thermal oil furnace systems are more thermally efficient and do not lose heat to the atmosphere through steam traps and leaks as in steam systems.

 It is important to reduce the cost of oil heat transfer furnaces is to have a very simple design and operation.

 Thermal oil systems are safer than steam systems because the system operates under low pressure (just the pressure of the pump to overcome the resistance to circulating the heat oil in the system).

Structure

Thermal oil system includes:

  • Thermal oil heating furnace (heating oil furnace) : KS oil and gas heating oil furnace has a horizontal or vertical shape. Oil furnace size is based on the calorific value of the technology, operating temperature and flow rate requirements.

The body of the KS thermal oil furnace is combined and arranged very reasonably by the spools receiving radiant heat, and the spools receiving convection heat. Depending on the capacity, the furnace body usually has two passes, three passes to maximize heat absorption from fuel combustion.

The burner is imported from Germany, Italy or from G7 countries. Fuel feeding to the furnace is fully automated.

KS thermal oil furnace is equipped with a heat recovery unit for hot air drying: in order to take advantage of exhaust heat, increase efficiency.

  • Heat exchangers : KS designs many different types of heat exchangers from typical plate heat exchangers etc. You can choose the type of heat exchanger depending on the process of heat use technology. . KS heat exchangers have been maximized heat transfer and system efficiency.
  • Oil expansion tank :
cau tao

KS’s oil expansion tank is a 2-in-1 device because it has 2 different tasks:

+ The degassing expansion tank is a place to store a volume of heat carrier oil that increases during heating.

+ The degassing expansion tank also helps to remove the gas in the device, ensuring accurate measuring device parameters, avoiding pump cavitation, making the thermal oil flow continuously to ensure that the heat absorption surface is always low, thus do not overheat the oil, avoid oxidation, help prolong the life of the thermal oil.

+ A special feature of KS’s oil expansion tank is that in addition to performing two tasks of expansion – degassing, this device also prevents the hot oil flow in the system from heating the oil on the expansion tank, minimizing heat loss. .

  • Circulation pipeline:

Thermal oil piping system is made from ASTM standard heat-resistant seamless steel pipe and accessories suitable for hot oil environment such as expansion compensation, valves, heat-resistant gaskets, oil resistance, etc.

The diameter of the oil pipe is designed to match the oil speed in the pipe, ensuring the most economical oil flow capacity and pipeline resistance.

 The pipeline system is covered with insulation against heat loss, environmental safety and hygiene, in accordance with technical standards for fire prevention.

  • Pump system:

The heat oil pump is an important part of any thermal oil system.

Heat pump oil pump is a single-stage pump with air or water-cooled seals and bearings, the motor shaft is indirectly connected to the pump shaft through a shaft coupling. Depending on the characteristics of the operating temperature, cold start-up temperature and the properties of the heat carrier oil, Enthalpy selects the most suitable pump types for customers.

Working principle

Heat transfer oil furnace operating principle shoots through a spiral coil and generates energy from the hot products of combustion by heating the coil through radiation and convection. The coils heat the heat transfer oil or the liquid pumped through the heat transfer oil boiler. Heat transfer oil heats coils in various types of heat users. Unlike water or steam boilers, this heating does not put a lot of stress on the system.
The heat-generating medium is heat transfer oil. The hot smoke of the furnace preheats the oil to a temperature of 250-300 oC and is transmitted to the production line, heating the equipment. The liquid is heated by direct contact with the heating element, is pumped to the user for process heat, and returned to the furnace system. KS oil furnace is designed, manufactured, and intelligently operated through PLC, HMI, SCADA processing systems. The oil temperature system is always controlled to avoid shortening the oil life.

Advantages of using

 Thermal oil system does not need pressurization, stable heat supply
 The fuel used does not corrode equipment and pipelines, so the life of the blast furnace.
The temperature of the thermal oil can be up to 350 °
 Thermal oil furnaces do not require the use of additional chemicals during operation.
 The medium has a high boiling point, so it responds well to large and stable heat without increasing pressure.
 Operation and maintenance costs are lower than boilers.
 High safety: Safe operation for users
 Emissions below the regulated level ensure environmental safety.
