Thermal Oil Boilers - High-Temperature Heaters based on Heat Transfe

Hot oil heaters and thermal fluids: the complete guide

The great diversity in the characteristics of the heat recovery system, such as gas composition, aggressiveness of these gases, amount and type of ash, the required temperatures of the gas and of the heat transfer fluid, gas flow, heat differential of the heat transfer fluid, gas pressure at the intake of the heat recovery boiler and, therefore, the pressure that it can control, etc., etc

What Should The Boiler Pressure Be When The Heating Is On?

07/11/2019 · When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.

Thermal Oil Boilers - High-Temperature Heaters based on

In thermal oil boilers, a special oil-based thermal fluid is used as the heat carrier - instead of water or steam. This thermal fluid - also called heat transfer fluid (HTF) - operates at atmospheric pressure all the way up to above 300°C. Comparing this to water and steam, this would require a corresponding steam or water pressure of above 85 bar to obtain the temperature of for instance 300°C.

Thermal Oil Heater - for High Temperature Process Heating

In thermal oil heaters, a special oil (HTF) is used instead and it means that you can achieve operating temperatures up to 300°C at atmospheric pressure. The thermal oil heaters, type VTO and type ELVTO are customised and special designed thermal oil units, - respectively with fuel oil or gas-burner, or electrical heated (see above sketches).

19/01/2015 · The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi. The pressure the system is designed to operate at is usually 12- to 25-psi for a two-story house, and 18- to 25-psi for a three-story house.

Under these conditions, this thermal oil can be used for more than 30 years. Another advantage of this thermal oil is its low vapor pressure (1.06 MPa at 398°C), which reduces the pressure required in the solar field piping to keep the oil in a liquid phase when it is at its maximum working temperature. These properties, together with its affordable price, are the reasons why no other thermal oil is nowadays
