What kind of heater is a packing heater?

It could be a regenerative heat exchanger: abbreviated as regenerator. A type of heat exchange equipment used for regenerative heat exchange. It contains a solid filler to store heat. Fire grids are generally built using refractory bricks, etc. (sometimes metal corrugated strips, etc., are used as well). Heat exchange takes place in two stages. In the first stage, hot gas passes through the fire grid, transferring heat to it and storing it there. In the second stage, the cold gas passes through the fire grid, where it is heated by the heat stored in the fire grid. These two phases alternate. Usually, two regenerators are used alternately; that is, when hot gas enters one regenerator, cold gas enters the other. It is commonly used in the metallurgical industry, such as in the regenerative chambers of steelmaking converters. It is also used in the chemical industry, such as air preheaters or combustion chambers in gas furnaces, and regenerative cracking furnaces in synthetic oil plants.

Brother Glue said it could also be a filler/rubber gasket heater, designed to prevent the medium temperature from dropping below 0 degrees and causing the valve stem to fail to move properly...:lol See: http://www.sbt.siemens.com/sbttemplates/library/pdf/129200.pdf

2# xkchampion Regenerative heat exchanger/heater – is the English term really regenerative heat exchanger/heater? A search online seems to show something called a labyrinth packing heater, a labyrinth-type sealing heater – is it perhaps a **sealing heater?

The meaning of a word can only be determined when it is placed in its specific linguistic context; translating words or phrases outside of a sentence makes no sense. Similarly, translating sentences without considering the surrounding paragraph also lacks meaning. If a whole paragraph is provided, it will be easier for everyone to help you

Based on the discussions above, translating it as a heat exchanger is more professional.

packing heater packing refers to packaging materials, filling substances, sealing materials, and luggage； Heater refers to the person who performs heating, as well as heaters, heating systems, electric heaters, pistols, and heating devices. It should be translated as: regenerative heater/heat exchanger, packing/sealant heater, electric heater with insulation ； In industrial applications, heat exchangers are referred to as heat exchangers, air preheaters, or electric heaters with insulation – these terms can serve as a reference for translation based on the context.

Is “packing” simply “entangled roots”? ? Upon looking, it turned out to be a direct “phonetic translation”.
