Is the waste heat boiler a heat exchanger?

Is a waste heat boiler a heat exchanger? Personally, I think that fire tube waste heat boilers can be considered as heat exchangers, while water tube waste heat boilers are different from heat exchangers and can only be said to be heat exchange equipment in a broad sense.
Boilers should actually belong to the category of heat exchangers
There is no need to discuss this issue. . Heat exchange equipment covers too many areas. . Boilers are definitely heat exchange equipment
Of course forget it, if there is no afterburning situation.
The relationship between energy conversion. Energy is conserved.
The waste heat boiler is a relatively complex chemical unit equipment, especially the control is very complicated. It is classified as a heat exchanger, which cannot be said to be wrong. Those with supplementary combustion systems are more complicated. You can classify them as heat exchangers, but the design and operation must not be like ordinary heat exchangers.

First of all, you must understand that the original purpose of a waste heat boiler is to exchange heat. It is a heat exchange equipment. Boilers are directly heated by flames (such as flue-type waste heat boilers). A considerable part of the heat exchanger belongs to the category of pressure vessels (pressure >0.1MPA, volume >0.025m³, temperature >boiling point). Pressure vessels and boilers are two different things.
All boilers are heat exchangers. Fire tube boilers and water tube boilers are both heat exchangers. Although there is no combustion inside, the mechanism is the heat exchange process of high temperature flue gas and low temperature water.
Heat exchange is certain. However, the waste heat boiler is a heat exchange equipment that uses the waste heat of materials to produce steam.
It is a kind of heat exchange equipment, but the design of the boiler is not equivalent to the heat exchanger. Its design software is different from the general calculation software, and the qualification requirements of the design institute are different.
It is heat exchange equipment. * * From a management perspective, the heat exchanger and boiler are separated.

In a broad sense, boilers are all heat exchangers. They all exchange heat with water. Water absorbs heat to produce steam. Boilers are special heat exchangers or a type of heat exchanger. However, in terms of equipment classification, boilers are different from ordinary heat exchangers because their heat exchange methods are unique.
Heat exchange equipment covers a wide range of things, such as heat exchange equipment. Some equipment in the thermal system is of this type. Boilers must all be classified as heat exchange equipment.
The catalytic waste boiler can generally be classified into the broad category of heat exchange, but the structures of the economizer, superheater and evaporator are completely different.
The English name HRSG is the abbreviation of Heat Recovery Steam Generator. It is literally translated into Chinese as heat recovery steam generator, so it is essentially different from a boiler. It is just a heat exchange device.
