Fouling Resistance (Fouling): The existing heat exchanger has a history of no-to-minimal fouling over a long period of time. The sole minor fouling experience was caused by an event that has been mitigated by the installation of gas seals. This deposition process is called fouling. It starts gradually on the transfer (tubes or plates) and the thicknesses of the deposits increase throughout operation of the exchanger. If no action is taken, these fouling deposits troublesome both for fluid flow (significant increase in pressure drops) and transfer. This can even block flow within the exchanger (Garret-Price Somerscales Understanding concept of heat exchanger fouling is important. As fouling damages the surface of heat exchanger and reduces efficiency of it.

Dirty Truth about Heat Exchangers In this article, Matt Gutschow , co-founder of HeatCalc , provides some insights into the topic of heat exchanger fouling. What is fouling? What are t ee-ip.org Scoops about HeatCalc Read more news See more Heating or cooling of a fluid by another is made in a heat exchanger with heat dissipation from surfaces of the equipment. Over time, the Abstract Fouling results in a significant cost to the process and power industry, and a better understanding of the fouling behavior and mitigating measures is of interest to both personnel in operating facilities and research organizations. Fouling reduces the heat transfer rate and increases the pressure drop of heat exchangers.

Fouling and its effect on heat exchangers

Fouling in the crude oil preheat trains is considered as ~20% of all heat exchanger fouling [4]. Therefore, there is a profound interest in cutting down the energy losses due to fouling by proper monitoring and prevention methods. The fouling of a heat exchanger can be monitored via the overall fouling resistance, Rf . Rf, is defined as the difference between dirty and clean overall There are other types of fouling mechanisms that occur individually and simultaneously. The effect of these sediments and their effects on heat exchangers are detailed by Epstein [5] and Pekař and Kubalčík [6]. Crystalline/scale fouling is a common type of fouling frequently used for reversing the solubility salts that is found in water. The solubility (salt In heat exchanger design, a fouled U value (Uf ) is used in the design calculations in lieu of a theoretical clean U value to ensure that the heat exchanger transfers the required amount of heat, even in the dirty condition. Uf is calculated from the theoretical clean U value (Uc) per equations 2, 3 or 4. While different terminologies (fouling factors, fouling margins or cleanliness factors

Read Full Business Practice Policy & Regulation • Renewable Energy ABSTRACT Fouling on super heater tube in power plant is the cause of unplanned shutdown maintenance. Understanding how to prevent growth of fouling is necessary to get the stable power plant operation. A method to monitor the fouling resistance, Rf, of heat exchanger, especially super-heater of power plant, is presented. The historical hourly data of operating

Calculation for heat exchangers, lmtd correction factor and insulation losses. For operations trying to get ahead of fouling in inefficient ways, they rack up avoidance costs. Some applications will install larger heat exchangers and tubes to allow more liquid flow even if fouling occurs. This increases the rate at which the liquid needs to be heated and moved, and the costs of running the heat exchanger.

As fouling develops the overall heat transfer coefficient will vary from point to point within the exchanger. So, the calculation of the heat transfer that occurs under fouled conditions would require that the basic heat transfer equation be applied at number of points within the exchanger and the results summed over the length of the exchanger (integration over “space”). Since, the Abstract – This article discusses the fouling and its effects on heat exchanger performance. In process industries the use of heat exchanger is up to 20 to 25% of the whole machineries. The functioning of the process industry depends mainly on the effective functioning of
