WideGap is a heat exchanger used for applications involving fibrous liquids, highly viscous fluids, and fluids containing coarse particles. Diabon® is a graphite plate-and-frame heat exchanger used for tough corrosive media. AlfaQ is an AHRI performance certified gasketed plate-and-frame heat exchanger.
In shell-and-tube heat exchangers the flow enters different tubes in parallel. When tubes start to foul, the local Spiral Heat Exchanger Type 1 Spiral Heat Exchanger Type 2 The Type 1 is a good choice when one, or both, fluids are foul- to vacuum condensation duties. There are many different configurations of Type 2, the two most common HEat ExcHangEr SolutionS For tHE oil and gaS induStry HE-1 Overhead condenser The shell & plate heat exchanger is well suited for condensation of light hydrocar-bons leaving the top of the fractionator. The heat exchanger enables a close temperature approach and is well suited for preheating the boiler feedwater, thus, saving energy con-sumption in
Sep 15, 2018 · For example an air cooled chiller may use a shell and tube heat exchanger for the evaporator, a finned tube or micro channel heat exchanger for the condenser, a brazed plate heat exchanger for the compressors oil lubrication cooling and a gasket plate heat exchanger to indirectly connect the chiller to the central cooling circuit. Heat Exchanger Heat Transfer CoefficientsCondensation of low pressure steam:700 - 850:125 - 150:Condensation of organic vapors:350 - 500:65 - 90:Plate heat exchanger:liquid to liquid:1000 - 4000:150 - 700:Spiral heat exchanger:liquid to liquid:700 - 2500:125 - 500:condensing vapor to liquid:900 - 3500:150 - 700:Overall heat transfer coefficient calculator;
Jul 17, 2014 · On a heat exchanger using a modulating temperature regulator to heat fluids under 212°F, the steam pressure in the shell can be 0 psig. To assure condensate drainage, the steam trap must be mounted below the heat exchanger outlet tapping and it must drain by gravity into a vented condensate return unit. The Cause of Cracked Heat Exchangers - Avoid this Dec 02, 2015 · Overheating causes nearly all premature heat exchanger cracks. When a furnace cannot get enough airflow, the heat exchanger overheats and suffers excess stress from expansion and contraction. Over time, the heat stress causes cracks near weak areas such as bends or welds. The most common cause of an overheated heat exchanger is as simple as a dirty air filter. A clogged air filter restricts airflow through the furnace, overheating the heat exchanger
An ACHE is a device for rejecting heat from a fluid directly to ambient air.This is in contrast to rejecting heat to water and then rejecting it to air, as with a shell and tube heat exchanger and a wet cooling tower system. The obvious advantage of an ACHE is that it does not require water, which means that plants requiring large hes spiral plug-resistant heat transfer - Heat ExchangerThe spiral heat exchanger was developed in the 1920s for use in Overhead condensation and evaporation applications type C:Cross-/Counter- Or Co-Current-flow One cover closes the spiral body; SUPERMAX Shell & Plate Heat Exchangers handle liquids, gases
describing how the shell and plate heat exchanger can help solve these problems. The overhead condenser in a CDU is a perfect example of where good engineering practice regarding the design of the heat exchanger is required, and where the RAM is extremely important for the refinerys output.
