Why should the inlet and outlet nozzles of heat transfer fluid be connected together?

No, it's going to leak together.

The heat conduction oil furnace belongs to the liquid phase circulation boiler, and the heat conduction oil flows out of the heat after absorbing heat by the heating equipment, and then returns to the boiler through the circuit to be reheated and then flowed out, and the heat is continuously transported to the heating equipment. Classification of properties of heat transfer oil: Mineral oil type heat transfer oil is a product produced by appropriate fractions obtained from petroleum as raw material through distillation and refining (including solvent refining and hydrorefining) processes.

Its main components are mixtures of hydrocarbons. Mineral oil type heat transfer fluids include:

A mixture of paraffin-based hydrocarbons.

A mixture of naphthenic hydrocarbons.

A mixture of aromatic hydrocarbons – a mixture of aromatic hydrocarbons alkyl benzene.

SD series is made of Daqing ** fraction as raw material processing.

The YD series is made by extracting aromatic hydrocarbons from diesel fuel and hydrogenation.

The JD series is based on refined white oil based on long carbon chain saturated hydrocarbons as the base oil, and the representative of the LQ series is the mixture of aromatic hydrocarbons alkyl benzene, which is the representative of Changzhou Great Wall heat transfer oil LQ300 320 340 350 heat transfer oil.

At present, there are also many heat transfer oil production plants, there is no fixed base oil**, and they take a series name by themselves, and their product models often do not match the name.

Synthetic heat transfer oil is a product produced by chemical synthesis process with a certain chemical structure and a definite chemical name. According to the maximum allowable operating temperature, synthetic heat transfer fluids are divided into ordinary synthetic types and synthetic types with special high thermal stability. Synthetic fluids include:

Heavy alkylbenzene. Alkyl biphenyls.

Benzyl and dibenzyltoluene.

Biphenyl and diphenyl ether azeotropic mixture.

Terphenyls and partially hydrogenated terphenyls.

Alkyl diphenyl ethers.

Aliphatic hydrocarbons, polyolefins.

Silicone oil. Fluorohydrocarbons.

At present, the synthetic heat transfer oil used more in China includes: heavy alkylbenzene, biphenyl-diphenyl ether, hydrogenated terphenyl, dibenzyltoluene, xylene ether, etc. Among them, biphenyl-diphenyl ether is a gas-liquid dual-purpose heat transfer oil, with a temperature range of 12 400, hydrogenated terphenyl and heavy alkylbenzene have special high thermal stability and molding, and the use temperature of heavy alkylbenzene and hydrogenated terphenyl can reach up to 345

The representative of heavy alkylbenzene is Changzhou Great Wall heat transfer oil WD340 heat transfer oil.

Summary. Hello dear, <>

There are two layers of heating pipes for heat transfer oil heating, what are the consequences if the bottom is not heated.

Static heating of heat transfer fluids results in low service temperatures, low heat transfer efficiency, high coking susceptibility, and short service life.

Hello dear, <>

If the heat conduction oil is not heated below, what are the consequences of static heating of the heat transfer oil will lead to low temperature, low heat transfer efficiency, easy coking, and short service life.

If my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your wide concession and praise, your efforts are very important to me, and your support is also the driving force for my progress.

Selection of heat conduction oil heating system pipes: 1Pipe material?

Stress level? If the pressure is not high, you can also choose 3Other considerations?

The selection of pumps and pipes should consider the temperature;

The pump is changed to include a magnetic pump;

The gasket should be cracked and the trillion metal winding pad should be selected.

The high point is empty, and the low point is not less, because when driving or when the production fluctuates, there is gas to be discharged in the rental system, otherwise it will affect the increase of system temperature;

The storage tank is equipped with explosion-proof disc and safety valve, and the outlet of the safety valve should be led to a safe place;

To design the exhaust system (shutdown maintenance will export all the system oil).
