Heat exchanger, what is the difference between heater, heat exchanger and heating furnace?

main difference: Direct heating and indirect heating.

Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid. It is also called heat exchanger. There are direct contact type, regenerative type, partition type, and intermediate heat carrier type. Electric heater. Heat is the process of converting electrical energy into thermal energy. Heating furnace is a device that heats materials or workpieces. According to the heat source, there are fuel heating furnaces, resistance heating furnaces, induction heating furnaces, microwave heating furnaces, etc. To heat the mixture of CO and H2 from normal temperature to 245℃, it is recommended to use a heating furnace.

I think it is best to use heat exchange equipment for gases such as CO and H2. After all, hydrogen is flammable when exposed to air. If heating equipment is used directly, the safety hazard may be greater.

Heat exchanger, the concept of heat exchanger should be the same, both achieve heat transfer between medium and medium through equipment.； Heaters and heating furnaces are heating equipment that generate heat sources. For example, heaters use electric energy, while heating furnaces use electric furnace wire, oil, gas, electromagnetic induction, microwaves, etc. to generate heat sources. To heat the mixture of CO and H2 from normal temperature to 245°C, a heat exchanger should be used for heating. It is best to use superheated steam for heating, which is safe and suitable.

Mainly due to different heating methods and heat transfer methods, which are divided into direct heating and indirect heating. It is recommended to use a steam heater or use a heat pipe to recover heat from the higher temperature exhaust gas.

The third floor is very comprehensive and you can distinguish heat exchangers according to their functions.: There must be two media, the hot medium needs to be cooled, and the cold medium needs to be heated. So it's called heat exchange. Heaters and heating furnaces are simply used to heat the medium. Agree with the use of superheated steam heating.

Just to add: Heater does not only refer to electric heater, the heat exchanger used in power plant heating network is also called heater. If it refers to heating network heater, it is the same thing as heat exchanger and heat exchanger.

The difference between various heat exchange equipment mainly depends on the heat source and heat transfer method. The following points should be considered when heating different materials.: 1. For the safety of the equipment, it is best to exchange heat if it is flammable or explosive. 2. The usage conditions of the equipment site and whether there is a heating source. If there is no second medium heating source, it is still convenient to use electric heating. It is recommended that the temperature is not too high (below 350) and it is best to use heat exchange, which is easier to achieve the effect. If the heat is relatively large, it is better to use electric heating, which will have a better effect. Personally, I think that the heat exchange equipment itself will be very large because of the large amount of heat exchange, and the requirements for the heat source are relatively high. Electric heating would be very convenient. The above are all personal opinions, please give me some advice :)

1. The heater is wrapped with a glass fiber reinforced refractory fiber layer outside the multi-stranded resistance wire strands, and a metal wire reinforced refractory fiber layer is woven outside the refractory fiber layer. The double-layer coating that is closely combined and distributed along the entire length of the resistance wire strands and the resistance wire strands in the center form an integral body that can be bent as needed. It is a direct heating monomer that can be in close contact with the heated object. The heating monomer is repeatedly wound into a strip shape according to the shape and size of the heated object, and then multiple parallel monomers are woven together laterally with metal wires to form a braided high-temperature electric heater that can be directly wrapped around the heated object for direct use. 2. Heat exchanger, also known as heat exchanger, as the name suggests, is to convert media of different temperatures into hot and cold. Its function is to reach the operating temperature of different media through the heat exchanger. No matter where it is installed, there is no limit as long as the equipment can be used. 3. Heating furnace is a device that heats materials or workpieces. According to the heat source, there are fuel heating furnaces, resistance heating furnaces, induction heating furnaces, microwave heating furnaces, etc. Applications include petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries. my country's relatively outstanding heating furnace manufacturers such as Ningbo Shenguang Electric Furnace Co., Ltd. 4. Heat exchanger Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also called heat exchanger. 　　English translation: heat exchanger Heat exchanger is an indispensable device to achieve heat exchange and transfer in the chemical production process. There are often some highly corrosive and oxidizing materials in heat exchange. Therefore, the materials used to manufacture heat exchangers are required to have strong corrosion resistance. The classification of heat exchangers is relatively wide: Reactor pressure vessel condenser reaction kettle spiral plate heat exchanger corrugated tube heat exchanger tube and tube heat exchanger plate heat exchanger spiral plate heat exchanger shell and tube heat exchanger volumetric heat exchanger floating head heat exchanger tube heat exchanger heat pipe heat exchanger steam water heat exchanger heat exchanger unit graphite heat exchanger air heat exchanger titanium heat exchanger heat exchange equipment, the material used to manufacture the heat exchanger is required to have strong corrosion resistance. It can be made of non-metallic materials such as graphite, ceramics, and glass, as well as metallic materials such as stainless steel, titanium, tantalum, and zirconium. However, heat exchangers made of materials such as graphite, ceramics, and glass are fragile, large in size, and have poor thermal conductivity. Heat exchangers made of rare metals such as titanium, tantalum, and zirconium are too expensive. Stainless steel is difficult to withstand many corrosive media and produces intergranular corrosion.
