can cut thicknesses from 0.5mm to 2‚500mm‚ the equipment is low cost and can be used manually or mechanized There are several fuel gas and nozzle design options that can significantly enhance performance in terms of cut quality and cutting speed. Process fundamentals The cutting process is illustrated in Fig. 1. Basically‚ a mixture of oxygen and the fuel gas is used to preheat the metal to its ’ignition’ temperature which‚ for steel‚ is 700°C - 900°C (bright red heat) but well below its melting

weapons became popular. Poison gas‚ such as mustard and chlorine became the number one thing to use. Gas was invented to cause fear to the soldiers the army was fighting. The gas could cause death quickly over a few days which was why poison gas was the most feared of all the soldiers. Poison gas could be used when the soldiers wanted to knock out a large amount of people without having to do much. Gun shots from a machine gun were more common but using the gas put the soldiers in more pain which

Cons of Natural Gas Drilling Gas drilling has had the most impact on Pennsylvania ever since it was discovered. Whether or not it would have a direct impact on the environment is the question everyone has. Or “is it too good to be true?” obviously there are flaws in the idea of natural gas drilling and I am going to point these out whether or not you see the obvious issues on the matter is for you too judge for one’s self. My final question to you is how many people really going to make a huge

Almost a decade and a half had passed and this gas station is standing still. The technology evolves fast but this gas station doesn’t seem to evolve with regards to the technology. The gas station wasn’t that aware of the computerized system other company is using. They are not aware yet of computerized inventory

Coal Seam Gas What is it? Coalbed methane‚ also more commonly known as coal seam gas (CSG) in Australia‚ is a type of natural gas removed from coal beds. It has been labelled as an unconventional natural gas along with tight gas and shale gas. They are labelled as "unconventional" as a result of their unusual reservoir types. It is removed from coal seams that are 300 - 1000 metres underground‚ and it is mainly composed of methane gas. It is typically extracted by drilling a steel-encased hole

Although Helium exists in the atmosphere of Earth in small quantities‚ it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol

Exhaust Gas Recirculation 1. INTRODUCTION All internal combustion engines generate power by creating explosions using fuel and air. These explosions occur inside the engine’s cylinders and push the pistons down‚ which turns the crankshaft. Some of the power thus produced is used to prepare the cylinders for the next explosion by forcing the exhaust gases out of the cylinder‚ drawing in air (or fuel-air mixture in non-diesel engines)‚ and compressing the air or fuel-air mixture before the fuel is

efficient distribution and transmission network. High voltage gas insulated switchgear (GIS) is ideal for such applications. The range of application of SF₆ Gas Insulated Switchgear extends from voltage ratings of 72.5 kV up to 800 kV with breaking currents of up to 63 kA‚ and in special cases up to 80 kA. Both small transformer substations and large load- centre substations can be designed with GIS technology. The distinctive advantages of SF₆ Gas Insulated Switchgear are: compact‚ low weight‚ high reliability

The oil and gas industry is one of the world’s largest‚ complex‚ and expensive industry. The prices of oil and gas are probably the most closely plotted products in the global economy. In this industry there are three main segment of value chain: upstream‚ midstream‚ and downstream. It is evident that energy source play vital input to human activities‚ development‚ and growth of the economy. Hence‚ it is believed that after the industrial revolution‚ accessed clean‚ inexpensive and reliable energy
