Help, what is the K value for heat exchange between flue gas and heat transfer oil? ?
Thread Content
As the title suggests, I would like to know the K value for heat exchange between flue gas and heat transfer oil ?
This should be related to the material of the heat exchanger
What about the experience points? What is the normal range for them?
This is related to the material thickness of your flue pipes as well as the thickness involved in heat transfer
Thermal conductivity refers to a material’s ability to conduct heat directly, also known as heat transfer rate. Thermal conductivity is defined as the amount of heat directly conducted per unit time, per unit temperature difference, through a unit cross-section and length of material. The thermal conductivity of heat transfer oil can be estimated at 0.1 W/m·°C. At 250 degrees Celsius and normal pressure, the thermal conductivity of carbon dioxide is 13.31 mW/m·°C, while that of nitrogen is 36.84 mW/m·°C. These values are provided for reference only
