Heat exchanger selection

In summary: Shell%20and%20Tube%20Heat%20Exchangers%20Selection.pdfIn summary, the person is looking for a specific type of heat exchanger, known as a quench cooler, that can cool quickly and to a high degree. The heat exchanger will be used to cool a gas containing particles, water, and permanent gases. The person needs the heat exchanger to be able to clean easily and recover heat while keeping the gas pressurized. They are looking for a method to select the appropriate heat exchanger, as they have not found one in Perry's handbook or Wikipedia. They are open to suggestions from others, including a book or journal article that can teach them how to choose

I'm in need of a specific heat exchanger (a quench cooler). It needs to cool fast (in seconds) and it needs to cool a lot (hundreds of degrees).

The coolant is water (making steam). The other side of the heat exchanger is a gas which can be compared to an exhaust gas: there are particles (aerosols), water (which will condense) and permanent gases. Inlet temperature is well above water's boiling point, (>250 deg C) so no water is present in liquid form when it enters. Exit temperature is room temperature, so a lot will have condensed. the aerosols are expected to make everything dirty in no-time, so cleaning the heat exchanger should be easy.

I know that often quench coolers are a type of flash vessel, that doesn't do a lot of heat exchanging. A quench tower (direct contact between coolant and gas) is also no option for me. I need to recover the heat, and keep the gas pressurized.

Question: where can I find a method to select the heat exchanger? To my surprise, Perry's handbook doesn't have a "heat exchanger selection", wikipedia only describes a lot of heat exchangers...

I hope somebody can point me to a proper selection method. (Can also be a book or journal article - I have access to both in abundance). A selection method would not solve the question, but would enable me to do that myself... teaching me how to fish, rather than giving me that one fish. :-)

Of course, there's nothing wrong with answering the technical question here.

Thanks in advance.

What is a heat exchanger?

A heat exchanger is a device that transfers heat from one fluid to another. It is typically used to increase or decrease the temperature of a fluid, or to recover heat from a hot fluid and use it to heat a colder fluid.

What are the different types of heat exchangers?

The main types of heat exchangers are shell and tube, plate and frame, and air-cooled. Shell and tube heat exchangers consist of a series of tubes inside a larger shell, with the fluids flowing in opposite directions. Plate and frame heat exchangers use thin plates to separate the hot and cold fluids. Air-cooled heat exchangers use air to cool the fluid instead of another fluid.

How do I select the right heat exchanger for my application?

Selecting the right heat exchanger depends on several factors, including the type of fluids, flow rates, temperature and pressure requirements, and space limitations. It is important to consider these factors and consult with a heat exchanger specialist to determine the best type and size of heat exchanger for your specific application.

What materials are commonly used for heat exchangers?

The materials used for heat exchangers depend on the application and the type of fluids being used. Some common materials include stainless steel, copper, aluminum, and titanium. It is important to select materials that are compatible with the fluids and can withstand the operating conditions.

How can I ensure the efficiency and performance of my heat exchanger?

To ensure the efficiency and performance of a heat exchanger, regular maintenance and cleaning are essential. This includes cleaning the tubes or plates, checking for any leaks or damage, and monitoring fluid flow rates and temperature differentials. It is also important to select a heat exchanger with a high heat transfer coefficient and proper sizing for the application.
