Use Distilled Water in Cooling System

@ December 12, 2012 6:01 AM in Use Distilled Water in Cooling System

Hello Friends,

Cooling systems frequently use water to dissipate heat because it possesses a much higher "specific heat" index. In fact, water has a higher index than any other common substance. This high specific heat means water requires much more energy to change its temperature than other substances, which in turn makes it the optimal medium to regulate temperature. Distilled water offers no regulatory advantage, but its purity minimizes the build-up of residues within a system.

Thanks and Regards,

Remove Limescale From Shower Heads

@ December 6, 2012 1:48 AM in Remove Limescale From Shower Heads

Hello Friends,

When your shower head starts shooting water in all directions or the water is barely coming out of your shower head, then you know there is limescale buildup that you need to clean out. Some shower heads are easy to remove from the shower arm while others you will need to clean while still attached to the wall.

* Unscrew the shower head from the shower arm using a wrench. Wrap masking or electrical tape around the shower head where you will be using the wrench to protect the finish.

* Submerge the shower head into a container of one part vinegar, one part water. Make the vinegar/water mixture deep enough to completely cover the shower head. Soak the shower head for at least three hours. If the limescale is thick you should soak it overnight.

* Remove the shower head from the vinegar/water mixture and rinse with clean water. Check for any stubborn limescale deposits left behind.

Thanks a lot!

Wood Boiler Water Treatment

@ December 4, 2012 12:16 AM in Wood Boiler Water Treatment

Hello all,

Wood boiler water treatment is critical to the proper maintenance of a wood-fired boiler heating system. If operated and maintained properly, a wood boiler is an economical and environmentally friendly alternative home heating source. Treating the boiler water to prevent corrosion and scale buildup will keep the system operating at maximum efficiency and will extend its useful life by many years.

Wood boiler water needs to be treated on a regular schedule to prevent corrosion, scale buildup and biological growth. Supply water from a well or a municipal water system contains impurities such as calcium and magnesium that can precipitate to form a layer of scale inside the boiler and other system parts. Scale buildup is a serious impediment to heat transfer and will reduce the efficiency of the system, resulting in wasted fuel and increased operating costs. Iron and steel parts inside the system will rust in the presence of water and oxygen. This corrosion will decrease the life of the system by causing leaks and failure of parts. Bacteria, fungi and algae can grow in untreated boiler water and accelerate corrosion.

Thanks a lot!

Build a Custom Water Cooling System

@ November 29, 2012 11:49 PM in Build a Custom Water Cooling System

Hi Friends,

Water-cooled PC systems have a number of advantages when compared to the more common and typical air-cooled systems. For starters, PC coolant boasts a higher thermal conductivity than air. High-performance gaming and media machines can be uncomfortably loud with all the extra fans. Water-cooled systems are a lot quieter and are proven to cool the PC at a more effective rate.

Buy the water blocks that your new system will be cooling. There should be blocks for your CPU, memory, hard drive and video card. Select all the appropriate blocks for your custom system. For the best performance, purchase a water block for each of the hardware pieces. However, it is not necessary to acquire a block for all these pieces.

Thanks and Regards,

Cooling Tower Specifications

@ November 27, 2012 4:02 AM in Cooling Tower Specifications

Hello Everyone,

Many types of machines and equipment generate a great deal of heat. To get rid of much of this heat, engineers often rely on cooling towers, which take cool water and air and remove heat from various sources. These towers are enormous and have various unique specifications depending on the environment that they will operate under and the extent to which the owners want to remain efficient and environmentally friendly.

Thanks and Regards,

Invest in Water Stocks

@ November 22, 2012 6:11 AM in Invest in Water Treatment Companies

Hi bill,

Just little thing on Invest in Water Stocks I want to share with you:

Every child in school knows water is one of the most basic human needs, and most investors understand that water is a critical and strategic natural resource. And yet, pure plays on water are extraordinarily rare in the stock market. Most equities that are considered “water stocks” are really companies that provide technology for the pumping, piping or filtration of water and wastewater. These tend to be cyclical business that can be in either feast or famine depending on the state of the economy. Other so-called water stocks simply hold leases on land above underground water sources as a sole asset and may lack any means of actually utilizing the water that is technically owned.

Look for catalysts. Did a company get a new no bid contract with a foreign government or municipality? Or, did it just have to issue more stock to fund yet another geologic survey. Even a stock intended to be a long term investment is better bought before a positive catalyst than after.

Design Water Cooling Systems for Computers

@ November 18, 2012 10:11 PM in Design Water Cooling Systems for Computers

Hello Guys,

Water-cooled PCs and servers are becoming more popular as we try to fit our computer systems into tighter, more confining spaces, where air-flow and fans can't keep our systems from overheating. The tips listed below use components found in a typical water-cooling kit. You can build some of these components yourself, but the cost difference is negligible.

* Plan where everything must go and make sure your PC's case is large enough to accommodate the water cooling system.

* Decide on how you want to attach the heater shroud to the heater core found in your kit. You can use 3B weld or threaded rods inserted through the four holes in the core, fastened by small nuts at either end. Using the rods is preferred, especially if you don't want the shroud to be a permanent component in your system.

* Check inside your PC's case to see if you have a hard disk drive rack blocking where you need to install the heater core in the frond of your case. You may need to remove the rack by either prying if off or drilling out the rivets holding onto the case.

Calculate Cooling Tower Evaporation

@ November 13, 2012 10:07 PM in Calculate Cooling Tower Evaporation

Hi Everyone,

A cooling tower is a large tower or structure that lowers the temperature of a power plant or piece of equipment. It works by cooling a water stream and then getting rid of any extra heat. Air is transporated into cooling towers via evaporation. The following is a simple formula for calculating the evaporation in a cooling tower.

Instructions:
* Take the number of gallons of circulating water per minute and multiply that by the difference between the temperature of the water in the top of the tower versus that bottom of the tower. The degrees should be in Fahrenheit.

* Take the sum from Step 1 and multiply it by the specific heat of water, also in Fahrenheit.

* Take the sum from Step 2 and divide it by the latent heat of vaporization of water.

* An alternative method is to subtract the blow-down from the makeup. Then, subtract the windage losses. You can get the windage losses from the manufacturer of the cooling tower.

What Are the Causes of Water Heater Element Corrosion?

@ November 6, 2012 5:47 AM in What Are the Causes of Water Heater Element Corrosion?

Hi Friends,

When a water heater stops producing hot water, the first thing that usually goes bad is the heater elements. The elements are eaten away by the corrosive effects of the dissolved minerals and chemicals in city water. So, by understanding the exact chemical reactions that take place, I cannot understand why the elements corrode to the point of becoming ineffective and what are the causes of water heater element corrosion. Any idea on it, please share with me.

Thanks a lot!

Water Boiler Treatment Methods

@ October 31, 2012 2:54 AM in Water Boiler Treatment Methods

Hello Everyone,

Water boilers are designed to efficiently heat water in a hot water tank before it is cycled around to where it is needed in the house. Water boilers work best when water is pure and free of any contaminants. Unfortunately, not much water is this clean, especially water that comes from wells and other alternative sources. To properly clean this water, manufacturers create several different methods to treat the water used in boilers.

External Treatment
External treatments are designed to help clean water before it gets to the boiler at all. These systems are used when the water is dirty enough to harm the boiler easily through constant use. There are many methods used in external treatment, but some of the most common are evaporation and deareation, where water is turned into steam and back into water to purify it.

Bacteria Treatment
Bacteria tends to grow inside the heated conditions of boiler tanks. This type of bacteria can survive in heated conditions and tends to produce harmful contaminants like sulfur and iron. These bacteria are very difficult to fully remove. Owners need to flush the entire system, clean it out, and remove any components that are heavily invested with the bacteria.

Corrosion Protection

Corrosion occurs when the water rusts the pipes and tank the boiler uses. This type of corrosion is encouraged by two different factors, oxygen in the water and acidic water elements. Corrosion treatments use filters to remove oxygen (air) from the water, and chemical additives to add alkalinity, helping reduce the effects of acidic water.

Scale Protection
Scale is the layer of minerals that form on tank surfaces and pipe interiors due to dissolved minerals in the water. Most boilers have rods made out of magnesium or a similar material: these rods attract dissolved minerals and bond them to the rod instead of letting them precipitate out of the water in the heat.

What Happens When a Steam Boiler Explodes?

@ October 25, 2012 3:11 AM in What Happens When a Steam Boiler Explodes?

Hi Friends,

When used and maintained correctly, steam boilers can be an effective source of heat or power for homes, generators and machinery. However, a poorly treated steam boiler can fail or even explode. While most modern steam boilers have many safety features to prevent explosion, older or simpler designs may still be at risk. So, I want to ask about the effects of steam boiler when it explodes. Any idea on it, please share with me.

Thanks in advance!
