How to Optimize the Design of Finned Tube Phase Change Heat Storage

-
图片
  Finned tube structure Finned tubes are widely used in power, chemical and other industries. Many spiral heat transfer surfaces or threaded tubes can be regarded as finned tubes. It has a significant effect on expanding the heat transfer area and promoting turbulence, and it has a great effect on both single-phase-convection heat transfer and phase-change convective heat transfer.  The structure of the finned tube heat exchanger is basically the same as the general shell and tube heat exchanger. Just use finned tubes instead of light tubes as the heat transfer surface. Finned tube heat exchangers are also often used to heat or cool the gas outside the tube, and steam or water is passed through the tube, such as air coolers, boiler economizers, radiators, etc.   Finned tube material The finned tube has a wide range of materials, including stainless steel, carbon steel, titanium and copper alloys, etc. The corrosion resistance of the industry has greatly increased.

EVERYTHING YOU CAN KNOW ABOUT HEAT EXCHANGER

  A heat exchanger is a device designed to transfer heat between two or more fluids with different temperatures (ie liquid, vapor or gas). Depending on the type of heat exchanger used, the heat transfer process can be gas-to-gas, liquid-to-gas or liquid-to-liquid and takes place through a solid separator that prevents fluid mixing or direct fluid contact. Other design features, including building materials and components, heat transfer mechanisms, and flow configuration, also help to classify the types of heat exchangers available. After discovering applications in a wide range of industries, we designed and manufactured a variety of heat exchange equipment used in heating and cooling processes. This article focuses on heat exchangers, exploring various available designs and types, and explaining their respective functions and mechanisms. In addition, this article outlines the selection considerations and common applications of each type of heat exchange equipment. Heat Exchanger therm

Fin heat exchanger cleaning

You will need to keep the fin heat exchanger clean every once in a while. You will find that you are able to keep it clean and take care of it with proper maintenance and cleaning, the longer it will make it last longer, which will be the better job. Step 1 Open The first thing you will do is open the lid of the  air cooler . Due to the cooling process of the air cooler, fresh air from outside circulates throughout the office or home. Every air cooler is different, so unless you have to open it before, you may need to look at the instructions and check to see exactly how to do it. Improper doing so may cause damage to your evaporative air conditioner. Step 2 Check The air in your room will never be out of date. This even allows you to enjoy a free operating unit, even if the doors and windows are open. After the cooler has been turned on, it is a good idea to take the pad and double check. If they want to be in good condition without debris or molds, then they will have to be replaced.

Everything you should know about U bend tube

  Murphy can make  U bend tube  in our factory according to customer requirements. The elbow is heat treated according to the customer’s requirements, and then hydrostatic pressure test and dye penetration test are performed as needed. U-shaped elbows are widely used in  heat exchanger  systems. Heat exchanger equipment based on stainless steel U bend tube plays an important role in the nuclear industry and petrochemical machinery manufacturing. U bend tube heat exchangers are specially designed for high temperature applications, especially steam condensing or hot oil systems. When the differential expansion makes the fixed tube-sheet heat exchanger unsuitable, and in some cases the floating head type (HPF) cannot be selected, the U bend tube heat exchanger will be selected. The surface of the finished U-shaped elbow should be free from scale and scratches after bending. Dimensional tolerance U-bend pipes are in accordance with relevant regulations of TEMA R.C.B. and ASTM A566 and ASTM

Fin tube for boiler economizer

  H type fin tube  waste heat recovery device (also called economizer) The concept of economizer The  economizer  is the heating surface in the tail flue of the boiler that heats the boiler feed water into saturated water under the pressure of the steam drum. Because it absorbs relatively low temperature flue gas, it reduces the flue gas exhaust temperature and saves It improves energy and efficiency, so it is called an economizer. Working principle of economizer 1. The economizer greatly saves fuel. The economizer absorbs the heat of the low-temperature flue gas, reduces the temperature of the flue gas, reduces the flue gas loss, and saves fuel. Since the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the expensive evaporation heating surface. 2. The economizer can reduce the temperature of the flue gas, recover the heat of the flue gas, im

Heat exchanger in wall hung boiler

图片
  Wall hung boilers have become the third largest gas product after gas water heaters and gas stoves, and wall-hung boilers are used most often in household heating. Wall-hung boilers can not only provide users with domestic hot water, but also heat the home. Wall-hung boilers can be divided into single-heating and dual-purpose boilers in terms of function, and they can be divided into instant heating and volumetric heating methods. The instant heating models are divided into casing machines and plate changers. What is the difference between a wall-hung boiler casing machine and a plate changer? How much do you really know? Did you choose the right one? The  heat exchanger  can be described as the core component of the gas wall-hung boiler, which is responsible for heat exchange between the flue gas generated after the combustion of the gas and the water in the system. From the perspective of the heat exchange structure of the heating and hot water functions of the ordinary wall-hung b

  Types of Shell and tube heat exchanger Shell and tube heat exchanger  is also called tubular heat exchanger. It is a partition type heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. Shell and tube heat exchanger has simple structure, low cost, wide circulation cross section, and easy to clean scale; but it has low heat transfer coefficient and large area. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is the most widely used type. Shell and tube heat exchangers include fixed tube plate steam-water heat exchangers, shell and tube steam-water heat exchangers with expansion joints, floating head steam-water heat exchangers, U-shaped shell and tube steam-water heat exchangers. Corrugated shell and tube steam-water heat exchanger, segmented water-water heat exchanger and other types. The main control parameters of the shell and tube heat exchanger
