A question about heating

At such high temperatures, using steam for heating would result in very high pressures, which is unsafe. However, heat transfer oil is different – it generates low pressures and is therefore safe. Safety and ease of operation are the main reasons why heat transfer oil is used!

For 150 degrees, it should be around 0.5 MPa of steam pressure, right? If your factory has a heat transfer oil circulation system, then of course you should choose heat transfer oil heating:lol

Heating with heat transfer oil requires low pressure, making it relatively safe. Compared to steam heating, there is less heat loss due to leaks resulting from poor system sealing; there is no heat loss from unrecycled condensate water; there is no heat loss caused by secondary steam generated by pressure drops; and there is no heat loss associated with waste discharge. Moreover, the temperature control is quite precise, with easy and accurate temperature regulation.

Heat transfer oil is usually diesel, as it is more convenient to use; whereas steam generation and condensate removal are more complicated.

Your facility uses a small amount of steam, and with steam heating there is the issue of condensed water that needs to be recovered; this problem does not exist with hot oil heating.

Firstly, under the operating conditions in your factory, by using heat transfer oil, the system pressure remains much lower than that when steam is used, ensuring the safety of the equipment； Secondly, heat transfer oil exhibits minimal temperature fluctuations, high thermal stability, and stable flow rates, whereas steam systems experience large variations in flow and temperature, which can lead to the condensation of the material being heated and thus disrupt production; this ensures process safety ； Third, the investment in a heat transfer oil system is low, the heat transfer oil can be reused, ensuring good economic benefits.

The heat transfer oil pipeline has low pressure, ensuring safety. But the temperature control is inaccurate ； Heat is released by utilizing the temperature difference; as the temperature changes, the amount of heat exchange is not significant ； Contaminates materials and the floor when leaked. Heat transfer oil is prone to oxidation, and it needs to be replaced regularly depending on its usage. The pressure in the steam pipeline is high; safety valves and other devices are installed in the pipeline, so there are no safety issues. The temperature control is highly accurate; it utilizes the latent heat to release heat, resulting in no temperature differences and high heat exchange efficiency ； It will not contaminate the materials or the floor in case of leakage. Try to use environmentally friendly and energy-efficient steam as the heat source. Heat transfer oil should only be considered in the absence of steam boilers.

Around 150 degrees is similar to the temperature of low-pressure steam; low-pressure steam definitely won’t work, so other types of steam at a higher pressure need to be considered. As for heat transfer oil, its heating effect is slightly better than that of steam, mainly because the temperature is easier to control compared to steam.

The heat transfer oil operates at low pressure, so it is very safe

Heat transfer oil has low latent heat, heats up slowly, and is relatively easy to control in terms of temperature
