natural gas consumption usually rises and falls with the seasons. In the winter months, which historically have used more natural gas for heating. We are trend towards using natural gas to produce electricity, as well as heat. Therefore, we are using more and more about natural gas per year. The peaks in the summer are becoming more common than ever now that natural gas is used for cooling our homes and businesses. The high demand for energy burns clean and efficient natural gas demands are constantly extract, process and transport natural gas to areas that need it most. You should also store the excess gas so it is ready for use. We collect certain amounts based on projections of consumption and store excess amounts to ensure that the offer is less than demand when the natural gas needs highest peak than expected. It used to consume all the coal gas. Coal gas is stored in gas holders from the mid eighteenth century. These were large, surface tanks slowly sunk into the

There has never been a better time for natural gas. It is the "other" of fossil fuels, touted as a clean alternative to coal and oil. It can be non-renewable, advocates argue, but it is a bridge or transition of fuel for a happier future. Not surprisingly, the industry has done a great persuade local residents, members of Congress and the general public that there is nothing to worry about. Chesapeake Energy Corporation, one of the major players in natural gas drilling in the Marcellus Shale, which stretches from New York to Tennessee, it has been announced as the operation environment. So when Cabot Oil and Gas, a Houston based energy company, was fined for various hydraulic fracturing spill in northeastern Pennsylvania last year, Chesapeake took the opportunity to distance themselves from what had become embarrassing. In addition to spills frack, there were numerous reports of contamination of drinking water wells in Dimock, PA. In the New Year's Day 2009, the dri

Natural gas is a fossil fuel that has methane gas as primary component. It is derived from organic material was deposited or buried under the earth, for millions of years. It contains heavier gaseous hydrocarbons such as ethane, propane and butane, and sulfur-containing gases. Natural gas has certain properties that allow their use for industrial or domestic. For example, it contains toxic ingredients that when inhaled is absorbed into the blood. Natural gas is tasteless, colorless, and when mixed with the appropriate volume of air and ignited, burns with a clean blue flame. It is considered one of the cleanest burning fuels, producing primarily heat, carbon dioxide and water vapor. Natural gas is odorless and before it is distributed to end users, is adding odorized thiols, which also helps in detecting any leak. Natural gas is lighter than air and tends to disperse in the atmosphere. In a state confined within a house, gas concentrations can reach explosive mixtu

    The structures of large aircraft are the wings, fuselage and empennage. The surfaces of primary flight control, located on the wings and stabilizers are ailerons, elevators and rudder. These parts are connected by seams, joints call. All joints constructed with rivets, screws or special fasteners lap joints. The clips can not be used in joints in which the materials to be joined do not overlap - for example, at top, tea and edge joints. An edge Fayed is a type of lap joint made when two metal surfaces are faced against each other, so that they overlap. The internal organs that aircraft are manufactured in four ways: grinding, stamping, bending, and extrusion. The metal becomes part milled gypsum caused by first setting and then either chemically etching or grinding. A stamped part is annealed, placed in a press forming, and then re-heat treatment. curved pieces are made of sheet metal mechanics using the emission curve and design procedures. A lump is an aircraft par

    Welding is a process of joining materials such as metals and plastics with heat or pressure. It is the most widely used today to join metals, and is widely used in the production of automobiles, ships, trains, buildings and bridges. Compared with welding and brazing which introduces a soft substance to hold pieces original cast together, welding metal melts to form a solid and a strong bond. Welding had been practiced since antiquity. The most popular method at this time was forge welding was used by blacksmiths. This method used to weld two metals together fighting over a hot charcoal. Today, modern technology has allowed the welders to work with much greater precision and greater weld compared to the past. The First World War provided the impetus for the development of welding technologies, as many countries were seeking the best and most efficient ships and aircraft welding for war. Thereafter, the welding technology became a modern art could be done manually, and

A centrifugal pump is a pump rotodynamic in nature that employs the use of a driver turning to increase the pressure of a liquid. These are commonly used to move fluids through piping systems. The liquid enters the pump along a road near the shaft is rotating. After the entrance, its speed is fast by the impeller causing the fluid flowing in the outward direction. Upon entry into the glass and has an exit to downstream piping system, which is why these bombs are found to be of great help due to the fact that they make larger discharges through small head. The inspiration for the centrifugal pump is believed to have originated from a water lifting machine that was invented by the Italian engineer Francesco di Giorgio Martini, in 1475, according to a Brazilian historian is believed to be the prototype of a pump applied centrifugal force. The first real centrifugal pump was invented in 1600 by Denis Papin. However, the vane pump Papin had straight rather than curved, and

Gears Gears are Power transmission elements. It is the Gears that decides the torque, speed and direction of rotation of all the driven machine elements. Broadly speaking, Gear types may be grouped into five major categories. They are Spur, Helical, Bevel, Hypoid, and Worm. A lot of intricacies are there in the different types of gears. Actually The choice of gear type is not a very easy process. It is dependent on a number of considerations. Factors that go into it are physical space and shaft arrangement, gear ratio, load, accuracy and quality level. Types of Gears Types of Gears A number of gears are manufactured using different materials and with different performance specifications depending on the industrial application. These gears are available in a range of capacities, sizes and speed ratios, but the main function is to convert the input of a prime mover into an output with high

first :Carburetors The carburetor is the part of an automobile engine that converts liquid fuel into vapor. This is mixed with a certain amount of air that allows combustion in the cylinders. All gasoline vehicles have carburetors, including boats and light aircraft. Carburetors are generally found in small engines and in older automobiles, especially those used in stock car racing. Most engines have only one carburetor though most modern engines that have bigger engines or more than 4 cylinders use multiple carburetors. The history of carburetors can be traced to the development of the wick carburetor by Donat Banki, a Hungarian engineer in 1893. Frederick and his brother built the first petrol driven car in 1896. Then in 1900, they built a 2-cylinder engine using the new wick carburetor. This car was taken on a successful 1000-mile tour, marking an important landmark in the use of the carburetor in automobiles. There Are Two Types Of Carburetors There are two

TECHNICAL PRINCIPLES OF GAS TURBINES FIRST: WORKING PRINCIPLES OF GAS TURBINES SECOND: TURBINE OPERATION FIRST WORKING PRINCIPLES OF GAS TURBINES INTRODUCTION: Gas turbines are considered as a heat engine working according to thermodynamic cycle of constant pressure. Air is used as the working medium in the majority of practical applications, where it is compressed and heated up then expanded. From thermodynamic point of view, it is possible to prove that the work taken from air or exerted on it, at high temperature levels, is higher than that at low temperature levels. Therefore, it is possible to obtain a quantity of work from the turbine during expansion stage of the cycle higher than the work exerted during compression. The difference is sufficient to overcome all different sources of losses in addition to a huge quantity as output power used in different purposes. As it is possible to add heat to the cycle by burning the fuel internally in the working medium

 Introduction to the BMW 3- and 5-Series The E30 3-Series range first became available in the UK in March 1983, and continued in production until April 1991, when the revised E36 3-Series range (not covered by this manual) was introduced. Convertible and Touring (Estate) models were introduced for 1988, and these models have continued in E30 form to date. The E28 5-Series models were introduced in October 1981, and were superseded in June 1988 by the revised E34 5-Series range, Touring versions of which became available from March 1992. Throughout this manual, E28 models are also referred to as “oldshape”, while E34 models are designated“new-shape”. The models covered by this manual are equipped with single overhead cam in-line four- and six-cylinder engines. Early 316 and 518 models are fitted with carburettors, but all other models are fitted with fuel injection systems. Transmissions are a five-speed manual, or three- or four-speed automatic. The transmission is mounted to th

What Is Nitrous Oxide? Nitrous oxide is a gas composed of two nitrogen atoms bonded to one oxygen atom. The scientific abbreviation for one nitrous oxide molecule is N2O where N is nitrogen, and O is oxygen. This is where the familiar phrase 'N-2-O' comes from when people talk about nitrous oxide. How Nitrous Oxide Makes Power Nitrous oxide kits make large amounts of horsepower by allowing an engine to burn more fuel. Burning more fuel creates higher cylinder pressures that will push down on the pistons with greater force. When the nitrous is injected into an engine and the initial combustion takes place, it creates enough heat to separate the nitrous oxide into its two components, nitrogen and oxygen. Once separated, the additional oxygen is then free to react with additional fuel. To run nitrous successfully and safely, you have to introduce precise amounts of additional fuel with precise amounts of nitrous oxide. All of the extra oxygen provided by the nitrous oxide mu

First things , the car engine is an internal combustion engine, of which there are a number of various types including diesel engine , gasoline engine , rotary engine and engine two times . The internal combustion engine works with the basic premise of injecting a small amount of high-energy fuel, eg gasoline or diesel in a small closed space, lighting and creating a massive amount of energy as a gas in expansion. The trick of the internal combustion engine is removed is the accusation of explosions like this hundreds of times for one minute and management to harness the energy that is thus created. Almost all cars use four-stroke cycle combustion to convert fuel into motion, the four strokes being - intake, compression, combustion and exhaust. In the beginning of the cycle the piston starts on top, once the intake valve opens, the piston moves downward, letting the engine take in a cylinder filled with air which also injects a drop Petrol. The piston moves back

Internal combustion 1.1) Introduction: The internal combustion engine is an engine in which the combustion of fuel and an oxidizer (typically air) occurs in a confined space called a combustion chamber. This exothermic reaction creates gases at high temperature and pressure, which are permitted to expand. The defining feature of an internal combustion engine is that useful work is performed by the expanding hot gases acting directly to cause movement of solid parts of the engine, by acting on pistons, rotors, or even by pressing on and moving the entire engine itself. We will first starts with the first Engine that had been made to move the first plane and will show The developments that done later to improve it. 2.1) The first 4-stroke internal combustion of a plane This is an computer drawing of one cylinder of the Wright brothers' 1903 aircraft engine. This engine powered the first, heavier than air, self-propelled, maneuverable, pilot
