Thermal oil

THERMAL OIL FOR INDUSTRIAL APPLICATIONS

What is thermal oil?

Thermal oils or thermal fluids are heat transfer media that are used to transfer thermal energy in those applications or processes where high temperatures are required.

One of its main applications is transmitting heat from the industrial burner boiler or industrial biomass boiler, to the different industrial processes/applications that require heat.

The process of thermal oil in a heat generation system using conventional industrial boiler or industrial biomass boiler

The heating of the thermal oil takes place through the heat generated by the combustion of the biomass in the furnace of the boiler, or of the fuel (natural gas, oil, fuel oil, etc.) in the burner. This heat is transmitted to the coils located inside the boiler, through which the thermal oil circulates.

The coils of the industrial boiler, where the thermal oil will circulate, must be designed and constructed in accordance with the regulations, dimensions and quality necessary so that, in addition resisting the high temperatures to which the thermal oil will be subjected, they allow an optimum speed for proper heat transfer. The aforementioned qualities will not only extend the lifespan of the thermal oil, but also of the industrial boiler and other equipment involved in the heat generation process. That is why, for this type of thermal oil heating processes, we recommend the configuration of water tube coils which, in addition to preventing excessive thermal oil degradation, speed up start-stop processes, avoiding the instantaneous evaporation process, among other problems and deterioration.

General technical advantages of thermal oil for its application in industrial sectors

Thermal oil is characterized by being a heat transfer medium of great versatility, that is, it can cover the specific needs of a wide variety of industrial sectors. Here are some of the main technical characteristics of thermal oil.

  • High temperatures (Up to 400 ° C in liquid phase) with minimum atmospheric pressures, which simplifies the design of the installation
  • Absence of corrosion (the fluid lubricates the installation)
  • High thermal inertia (the system retains the heat for longer)
  • Long life of the equipment (More than 20 years with standard maintenance and no need for major renovations)
  • Non-pressurized system
  • Low pressure design
  • Proportionally reduced CO2 and NOx emissions
  • Mixed temperatures that can be easily reached by different users in a single system.
  • Simpler civil works due to low pressure operation

 

 

Operational advantages of thermal oil in industrial installations

As we pointed out in the previous section, thermal oil is a thermal fluid whose use extends to a large number of industrial sectors. Here are what we consider to be some general advantages of using thermal oil:

  • Simple and accurate temperature control (temperature accuracy of ± 1º)
  • Very low maintenance cost
  • We avoid corrosion problems
  • Quick start-up and stop
  • Very simple operation (Does not require certified operator)
  • Does not require water or chemical treatment, maintenance of steam purges and condensate lines
  • No spillage costs (closed circuit)
  • Safer operation: less security elements required
  • Low freezing point
  • No heat losses due to purges, no loss of condensate

Thermal Oil Applications

Thermal oils as a thermal fluid are used in a wide variety of applications and industries where high temperatures are required. Some of the main industries in which these thermal oil thermal transfer systems are used are the following:

  • Chemical Industry
  • Wood Industry
  • Textile Industry
  • Food Industry
  • Plastic or Rubber Industry
  • Marine Applications
  • Gas and Petroleum Production
  • Machining of Metals, Paper and Cardboard
  • Construction Materials
  • Laundry Industry

Continuous Guidance

The choice of thermal oil is a decision that must be considered technically in the hands of professionals, that is why, as manufacturers in industrial burners and boilers industrial biomass boilers, we accompany our customers and offer continuous advice regarding the choice of the best type of thermal oil, for the particular installations and processes.

The thermal oil process requires making more decisions, therefore, in addition to advising our customers in the election phase, we help them continuously in aspects such as: performing the proper cleaning of the thermal oil, purged oil, etc., all oriented to ensure the maximum durability and performance of the equipment supplied.
