Tungsten carbide venturi nozzle is based on the principle of Berboulli, which has reasonable design on geometric surface, thereby forming a circulation of high flow, while also having the injection holes to prevent clogging. And the principle of the Venturi effect is when the wind blows over the barrier, and the air from the coarse to fine, the pressure of the leeward side of barrier is lower, so that it comes into a "vacuum zone" and causes air flow to run. When fluid at high speed runs through nozzle will lead surrounding fluid to come into a circulation, which mixed with the pumping liquor for enlarging the total capacity of circulate fluid and reaches the rate of 4:1. Therefore, the other energy consumption will be saved.

CWS is a kind of new-style fluid coal-based fuel, which is composed of 65% coal, 34% water, and 1% other chemical additives. It is low-sulfur and the temperature of center flame is lower so that the discharge of dust, SO2, NOX decreases and the efficiency is improved. Based on the long-term strategy, many countries regard it as the replacement of coal for developing and storing. As an important part of CWS burner, tungsten carbide nozzle CWS should has good atomizing performance. According to fuel quality and the different requests of atomization, the applications are also diverse. It can be specifically divided into air-blast, machining, rotating and ultrasonic. And their reasonable structure determines its anti-corrosion, heat resisting and lifespan, which is made of iron, tungsten carbide, pottery.

The earliest material for CWS is iron, which has good strength and heat resisting. Through heat processing, it can be improved for hardness and toughness. In addition, iron CWS nozzle is bearing the low angle of erosion so that its lifespan is short in practical applications. However, tungsten carbide belongs to fragile materials, its strength and impact resisting is weaker than iron so that it is not suitable for complicate nozzle. Actually, we often make tungsten carbide into ring or lump for inlaying on some parts abrased, such as Y-types used in America and Canada, multilevel CWS colliding nozzle used in China. What’s more, tungsten carbide is the prior choice of CWS nozzle, whose common lifespan reaches above 1000h.

First 9 Dart Checkout Fact

The World Darts Federation (also known as WDF) was founded in 1976 by representatives of 15 nations. All National Darts organizing bodies of all nations can become members of the WDF. The function of the WDF is to encourage the sport of darts amongst the different nations and to also gain international recognition for darts as a major sport.

The first World Professional Darts Championship was organized by the BDO (British darts organization) in 1978. This championship was for many years known as "The Embassy" – due to its sponsorship by Imperial Tobacco. In 2003 the government banned all tobacco advertising and in 2004 "The Embassy World Dart Championship" became "The Lakeside World Darts Championship" – or Lakeside for short.

In the mid 1980’s the BBC television program “Not the 9’O Clock News” did a harsh sketch on darts about "heavy drinking" in the sport, which caused great damage to the image of the game and players.

Although attempts have been made by certain players to rectify the damage, by drinking water on stage during TV broadcasts etc., all ITV coverage of the game was stopped in 1988.

The BBC also cut back on their coverage to the extend that only one major event, the Embassy World Championship was still shown by the early 1990’s

The Professional Darts Corporation (PDC) was established in the United Kingdom during 1992, when a group of 16 leading professional dart players split from the officially-recognized British Darts Organization (BDO). Certain players apparently felt the BDO did not do enough to encourage more new sponsors into the sport, and they also wanted to see more than one major televised event per year.

Interesting Fact

Both the PDC and BDO have World Darts Championship events. The PDC normally have their championship mid December to early January and the BDO from early January onwards.

In 2001 the BBC decided to expand darts coverage by adding the World Masters to their portfolio. Since 2005 viewers have been able to watch every dart thrown live at the World Championships. This was also the year that the BCC introduced interactive coverage via its BBC i service.

Darts are now been watched all over the world with several major tournaments being broadcast around the world.

In November of 2007 ITV also returned to darts after almost 20 years by showing the Grand Slam of Darts. A second PDC tournament was added in October of 2008 with the new European Championship.

Today the British Darts Organization (BDO) comprises of nearly 70 member counties, which organizes tournaments for players at all levels, from grass roots right up to professional level.

The game has also kept up with technology. Electronic dartboards are available with dozens of games build into them and keeping score automatically. Some will even talk to you. All these technological advancement has made the game more popular and much more accessible.

The primary Darts governing bodies are:

The WDF – World Darts Federation
The BDO – British Darts Organization
The PDC – Professional Darts Corporation

With the development of darts, people found tungsten is a type of high-density and durable metal. It’s perfect for making darts. Nowadays, tungsten darts become the professional player’s choice.
