A Quick Guide to Cooling Towers

Cooling towers are a prominent feature on the British skyline. These huge, convex structures punctuate both rural and urban landscapes, and have done so for decades lift shaft tower hire.

Nevertheless, many people are still unaware of what they are and the role that they play in industry. If you’re in the dark about cooling towers, here’s a quick guide to how they work.

What are they?

The towers are often found in power stations, factories and chemical plants. Their basic function is to remove excess heat. In a chemical plant, for instance, certain processes may generate excess heat. Using a heat exchanger and cool water passed through the equipment, this is removed.

In this way, they help control the temperature of a workplace, as is required by law. However, cooling towers may also be instrumental in industrial processes themselves. For example, electricity is generated in a power station when steam passes through a turbine. In order to maintain this cyclical process, the steam must condense before passing into the boiler and then back through the turbine. Condensation happens in a heat exchanger, which requires water cooled through this machine.

The large convex towers seen prominently in the UK are called natural draft towers. The height of these towers – which often exceeds 100m tall – creates the conditions for a natural process by which air is lifted and then condensed into water droplets as it falls back down. So the large smoke-like plumes often seem emanating from these towers are not smoke at all, but water vapour.

Another type found in industry is the forced draft tower. These contain fans which force air through the tower, in order to condense it into water. Forced draft towers are typically more box-shaped and much shorter than natural draft towers, and therefore are often less noticeable.

Smaller cooling towers

Although they are most commonly found in industry, the devices have many other applications too. For instance, smaller forced draft towers may be found on office buildings, as a temperature control mechanism. And in a domestic setting, they are most frequently found in air conditioners, to get rid of hot air.

Fences made from natural wood are the natural selection for most people. If you like the feel of nature to extend throughout the yard but to have the security of a fence then this is the right choice for you. No other material is as well known or as versatile when it comes to decorative features than wood. The problem is that it begins to rot or decay quickly when compared to the long lasting qualities of aluminum and wrought iron. It is vulnerable to insects as well as the weather even if it is weather treated wood.

The old stand-by and the best known ornamental fences are made from wrought iron. This heavy, durable and elegant material is known for its decorative twists and turns.

Are all of the panels to be the same or is there a pattern you wish to create? Will there be one or more gates and where will they be placed? It is best to map out the layout of the yard and the fences in relation to the house using graph paper. This will help to determine costs and the number of supplies needed.

More Military Uses For Crossbows

With the increased interest in crossbows, some would think that they are new on the scene. This couldn’t be further from the truth. Actually, crossbows have been used for military purposed for several millennia. One might also assume that with the advent of more modern and more lethal weapons that the crossbow would have been replaced by more modern weaponry. While this is largely true, there are still many active applications for crossbows in modern warfare and in guerrilla actions worldwide more.


In Europe, the British manufacturer of Barnet crossbows supplied many to the Serbian military that used them “in ambushes and as a counter-sniper weapon” against the Kosovo Liberation Army in the Kosovo War. Special Forces in Greece and Turkey are still using crossbows for military purposes due to their psychological effect as silent killers. The Green Berets of Spain continue to use crossbows as well.

The Chinese and other Asian countries use the crossbow at all levels of their military and Special Forces. Chinese traffic police have also been seen carrying crossbows – perhaps for the psychological effect they have. In 2009, during the Xinjiang riots, crossbows were used along with conventional arms to control protesters. The Indian Navy’s Marine Commando Force used crossbows in place of suppression handguns until the late 1980’s.

In North and South America the crossbow has served in several different capacities. The Peruvian army has provided crossbows and special rope for the purpose of establishing zip-lines where the terrain is difficult. The United States uses a crossbow launched type of grapnel hook as a mine neutralizer and to detonate mines triggered by trip wires. It was designed specifically for use in conflicts in the middle-east. Such devices can be used multiple times without revealing the user. The Brazilian Jungle Warfare Center also trains soldiers in the use of crossbows. They have proven to be of great value where noise discipline is essential. On this note, one can draw their own conclusions as to the many other military and clandestine applications this ancient weapon has and can be used for – and you will probably be right!
