Features of Convectional Heaters
Aug 18th
Convectional heaters are an excellent method of providing low- intensive heat to the medium. In these heaters combustion chamber temperatures are tightly controlled and tube wall temperatures are kept to a minimum to ensure safe and effective heat transfer. Heat up and cool down times are negligible. For cyclical operations, the burner control can be heater-based or process-based.
The conventional heaters process temperatures ranging from cryogenic to above 1100°F and pressure ranges from full vacuum to 2500 PSIG. Based on the requirements of the process, the heater coil configurations are finned, bare, or a combination of both. In addition, a wide variety of coil materials can be used to handle even the most challenging products.
Many of the new technology systems are designed to meet the most stringent emission requirements and include high turn down burners for superior system control. Control options are virtually limited with relay label and programmable logic system available.
Features of the latest technology convection heaters
- Custom designs for up to 95% (LHV) efficiency
- Can accommodate cyclical operations
- Strict control of temperatures of process fluid & combustion chamber
- Low tube wall temperatures
- Depending on the temperature distribution assorted coil materials are used
- Uniform heat flux
- Large capacities available
- Easy tube access
Conventional heaters are purely convective heat transfer units. The process of fluid flow inside and outside the externally finned tubes creates counter current heat transfer. As a result, the fuel gas temperature constantly decreases as it travels through the convectional section. The coil section is located above the combustion section, allowing for nearly 100% convective heat transfer into the process medium. The tubes are installed in the tube supports, leaving them free to expand without restriction.

Looking for Glow Sticks with Longer Shelf Life? – Purchase Glow Sticks in Bulk
Oct 24th
Many occasions demand the need of bulk glow sticks because of their extensive use in many places such as party decorations, accessories, for conducting different events, as party favors and so on. It is not surprised to get a huge number of glow sticks for all these purposes. Moreover, there are lot more advantages in buying glow sticks in bulk. Lets see what those advantages are.
Less expensive: It is a know fact that any goods purchased in bulk are less expensive when compared to the single pieces. The same rule works for glow sticks too. Bulk glow sticks are much cheaper than the regular single ones and are also more effective when compared to them.
Longer Shelf Life: There are many factors which affect the durability of the glow sticks. Among them shorter shelf life is also one factor which affects the durability of the glow stick. To increase the durability one should look at the bulk packed products. Bulk packed products have a longer shelf life when compared to the normal ones because bulk packaging is the special packaging which can only be seen when purchased in huge numbers. That packing protects the glow sticks from the damages caused due to transportation and also makes them safe and secure until the packet is opened.
Functionality: As the glow sticks have a longer shelf life they can glow for longer times. This increases the functionality of the glow sticks and makes them work more effectively.
However, glow sticks have a greater shelf life if they are stored in perfect storage conditions. Extreme climatic conditions will affect their functionality and can decrease their shelf period.

Know About Dental Calculus
Nov 21st
Apart from the common dental plaque, dental calculus or tartar is the other dental issue. The hardened dental plaque formed through the deposition of minerals is referred as dental calculus. It is yellow or brown in color. Avoiding proper brushing and flossing or neglecting removal of plaque often promotes dental calculus or tartar. However, it should be treated immediately, otherwise many other dental problems like gum inflammation, gum recession, tooth decay and so on may result.
Dental tartar may be formed above or below the gum margin. Calculus which is formed above the gum margin is termed as supra-gingival calculus. It is easily visible and hence, you can consult the dentist immediately to have treatment. However, calculus formed below the gum margin, often called as sub-gingival calculus, cannot be seen as it is present between the teeth and gums. The plaque is formed below the gum margin and cannot be easily cleaned by a toothbrush. In addition, you can only be aware of its presence only with the reveal of any serious dental problem like periodontitis. The most common material of the deposition includes calcium phosphate which is very hard and insoluble.
Unlike dental plaque, tartar cannot be removed easily by simple brushing or flossing. A professional dental cleaning by a dentist is only possible way to remove the tartar as it is very hard. Special instruments are used for cleaning the teeth and to remove the tartar and this process is referred as tooth scaling. Taking certain steps to prevent plaque formation avoids problems with tartar. Anyhow, once the tartar is formed, it is better to go to dentist for treatment. Certain tartar control toothpastes are also available which prevent dental calculus.
