The coolant is oil (mineral or synthetic), which has high temperature characteristics. Thermal oil boilers basically have a heat exchanger in the form of a coil for ease of use and quick access to nominal operating mode.
Diathermic oil boilers began to be used in the food, petrochemical, and gas industries, in the production of furniture, and building materials. Thermal oil boilers are used to heat heavy fractions of petroleum products or dehydrate crude oil. Where the operation of the entire enterprise depends on the high-temperature coolant.
Thermal oil boilers are used when it is necessary to heat various industrial facilities, as well as domestic premises. Mineral and synthetic oils act as coolants here.
The operating temperature in such boilers reaches 360°C, for this reason thermal oil boilers are used in production where heating needs to be done and where it is prohibited to deviate from the temperature schedule. If the power of such a boiler is more than 1 MW, in this case an air recuperator is installed. Recuperation of a thermal oil boiler increases its efficiency by 4-5% due to the removal of heat from flue gases while simultaneously directing this energy to heat the fuel. The coolant is oil (mineral or synthetic) which has high temperature characteristics. Thermal oil boilers basically have a heat exchanger in the form of a coil for ease of use and quick access to nominal operating mode.
