C1937 Thermal insulation standard addresses high temperature applications. The new standard focuses on layered, glass fiber felt pipe and board insulation for temperatures ranging from ambient to 1400°F (760°C). ASTM member Gordon H Hart notes that, compared to other fibrous insulation materials, the material covered in C1937 has a high compressive strength and is rated as non-combustible. #insulation

The coefficient of heat transfer (often denoted as h) is indeed influenced by the thermal conductivity of the fluid and the thermal boundary layer thickness. The relationship can be expressed as: h∝k/δh where: h is the convective heat transfer coefficient, k is the thermal conductivity of the fluid, δ\deltaδ is the thermal boundary layer thickness. This relationship implies that the heat transfer coefficient increases with the higher thermal conductivity of the fluid and decreases with a thicker thermal boundary layer. #shell and tube heat exchanger design#

Advantages of PHE at a glance   ＊High Heat Transfer Efficiency The flow turbulence inside plate heat exchanger maximizes heat transfer performance. Because of the high efficiency, the minimum logarithmic mean temperature difference could achieve 0.5℃. ＊Compact Design With service and maintenance space included, plate heat exchanger takes up only 20% space of what shell & tube heat exchanger takes because of the compact arrangement. ＊Self-Cleaning Action During operation, the fluid flow and the resulting turbulence can continue to remove dirt deposition from heat transfer surfaces, thus reducing fouling. ＊Long Service Life ＊Modularity This modular exchanger obtains a variety of configurations through various combinations of framework, plates and connection to meet the needs of a wide range of applications. ＊No Mixing of Medium The seal groove of plate heat exchanger form special drainage channels with which fluids are not allowed to mix. Even if there is leakage, the media always exude outward.

A common design mistake: Location of check valve Here is a practical example, helping to better understand the mistake and learn from it. Process Description:  The gas shall be preheated. In this regard, a preheater is used. To control the outlet temperature, quench water is added when needed. Problem: There is the possibility that the gas might go in reverse direction and pollute the BFW system. Cause: Lack of experience or abundance of work Effect: Pollution in BFW system Solution: Instead of adding check valve in such location, put the check valve after the branch. The following is the sketch, summarizing the note and showing the process. Credit: EIEPD

We all know U-values are important. Significant gaps, whether as a result of thermal bridging, poor design, or poor installation, causes greater heat loss because they allow warm air out. It can also increase the risk of condensation, which can cause significant issues such as mould or mildew.
