What Are Gas Turbine Expanders?-At A Look

Conventional gas turbine jet engines, like the turbofan, have been around for years. They power almost all commercial aircraft and are very reliable. Every time you board a commercial aircraft, this technology is providing safe and efficient power to get you to your destination. read here

A gas turbine engine varies greatly in design from the engine in your car. Air enters the front of the engine through the fan section, which runs on the N1 or low-pressure shaft. In high by-pass engines, which are the most efficient, 4 times the air that continues into the core of the engine, or more, is directed around the engine producing thrust. Then the air entering the core of the engine reaches the compressor section. Here, the air is compressed in stages as it continues rearward. Since air does not like to flow from areas of low pressure to high pressure, turbine engines rely on the cascade effect. The compressor, running on the N2 shaft or high-pressure shaft, contains stages of rotor blades. These rotor blades are small titanium airfoils radiating from the shaft. Just like an aircraft wing moving through the air, these blades are positioned to produce an area of low pressure on the top and high pressure underneath. Since these blades are angled forward, the low pressure area is facing forward in the engine and the high pressure faces rearward. In between each set of rotating rotor blades, there is a ring of stationary blades called the stator vanes. These are identical titanium airfoil shaped blades positioned opposite to the rotor blades. As the area of high pressure behind the rotor blades pass the area of low pressure in front of the stator blades, the air flows from the high pressure to low pressure. This is continued through the compressor section until the pressure is increased much higher than the outside pressure.

Once the air exits the compressor section of the turbine engine, it enters the combustion section. As a result of the increased pressure, the air is at higher temperature. Fuel is injected into this heated air and a spark is added to ignite the mixture. During combustion, the air rapidly heats and expands further. This increases the pressure in the combustion chamber forces the air rearward through the high-pressure compressor turbine. Here, energy from the expanding air is used to turn the turbine which transfers energy through the N2 shaft to power the compressor in the front of the engine. After passing through the compressor turbine the air continues to the power turbine. This is where most of the energy from the air transfers through the N1 shaft to the fan producing most of the engines thrust. The remaining air exits the rear of the engine and gives the engine about twenty percent of its total thrust.

The gas turbine engine basically uses the same intake, compression, power, and exhaust cycles as your automotive four stroke engine. Turbine engines only vary in operation from a four stroke engine. The simplicity of this engine has allowed it to remain the essential engine of commercial aviation.

Ultimate Guide To Sealcoating Your Driveway

Sealcoating your asphalt commercial parking lot can extend the life of your investment by years, which in turn will save you money in the long run to the tune of $1000’s for even a small parking lot. Unlike a driveway, doing this yourself is not cost effective. If you are a typical business owner or property manager, you already have a list a mile long to do.

Since the parking lot is often the first place your customers can get a 1st impression of you, why allow your parking lot to get worn & cracked? Short of just looking much better, we know sealcoating services done professionally can extend the life of your lot. Checkout read more .

We all know that the New England winters can wreak havoc on pavement. Periodic pavement maintenance can double the life of your pavement and reduce the likelihood of larger repair issues, while providing a smooth, clean jet-black finish for your parking lot that will beautify your business…..IF it is done correctly. By sealcoating now, you can avoid costly types of asphalt repair services like potholes & overlays.

Parking lots are often exposed to sun all day, everyday (when it is sunny). Sealcoating (done correctly) prevents oxidation and resists the ultraviolet rays that come with that consistent exposure. Over time the asphalt binder (tar) hardens & this hardening results in a brittle surface that eventually cracks. when you have a crack in the pavement, it enables water to penetrate the pavement, often into the sub base, weakening it.

When the temperature drops well below freezing, as it often does here in New England, the cracks grow exponentially. Drag a plow over those cracks & you get a pot hole pretty quick. Sealcoating protects the surface and fills surface voids, reducing pavement’s exposure to oxygen and water and extending pavement life by providing a protective shell that prevents water from penetrating through the asphalt.

Believe it or not, oil & gas that leaks from vehicles can wreak havoc on pavement. A layer of sealcoating resists this materail & does not allow it penetrate into the pavement. The professional-grade coal tar sealer that JDK uses contains additives that enable it to resist any such leaks. The sealcoat is a dark color which also hides the stains of leaked oil & gas.

So by sealcoating your parking lot, it will last longer (sealcoating is much less expensive than re-paving) & look much better. This gives your customers the confidence that you are a viable & professional business. Hey, in this economic climate, every little bit helps, right?

One more thing, sealcoating your driveway is something you may be able to accomplish on your own during the weekend, however, a parking lot sealcoating co is best left to a professional sealcoating company. Dont be fooled by the cheapest quote either. More on that for our next article.

Important Tips For Preventing Water Damage

Here are five tips on how you can prevent water damage to your house.

  1. Have you ever thought about maintaining your house on a regular basis? This seems to be one of the biggest problems with homeowners. They won’t fix anything, until it becomes unsafe or unusable. Make all of the necessary home repairs as soon as possible, to eliminate additional home repair costs in the future.tips on water removal from WaterRestoUSA.com

2. Here’s one, what about inspecting your house on a regular basis. This is probably the most important way to prevent water damage to your house. Inspect your home at least twice a year and it wouldn’t be a bad idea to check underneath your sinks at least once a month for any small water leaks.

3. Use the correct building materials. Just because something makes sense, doesn’t mean that you won’t have any problems with it. I don’t know how many times I see treated lumber, cedar or redwood sitting on the ground, because the homeowners think it isn’t going to rot.

4. How about educating your family. If no one in your family knows what to look for, you’re going to need to do all of the work yourself. It wouldn’t be a bad idea to teach everyone in your family, what to look for. If you have water leaking from a faucet or drain pipe, now’s the time to show everyone in your family what a water leak looks like.

Water damage prevention can save you money, it’s a well-known fact, that more people, spend more time, planning their vacation than they do on home repair prevention. If it’s too late and the water damage is already a problem, you should fix it as soon as possible to prevent additional home repair costs.

Gas Turbine Repair And Maintenance

A gas turbine runs or fails on the strength of its parts. When you look for a company to help you with supplying and repairing these parts, you should settle for nothing less than the highest quality workmanship. Your turbines need to be extremely precise, well-built replacement parts that will revitalize older turbines and keep them running at their full potential. Poor quality in replacement gas turbine parts is a recipe for disaster and lost work time, as well as possible further damage to other components. Only a company with an intricate, carefully engineered process to manufacture after-market parts is worth your time. The ideal parts company will also offer a warranty on its work and will have the backing of years of research and experience.You may want to check out Turbine Maintenance for more.

Precision Manufacturing

In order to provide years of smooth functioning with minimal down time, gas turbine parts must be built with the greatest possible attention to precision. A reverse engineering method using advanced mapping technology defines the precise parameters of each part, then builds them to exact specifications. In order to match replacement parts with existing equipment, engineers should work closely with clients to ensure a perfect fit.

Capital Parts

Capital parts are the durable, hardworking components at the core of a gas turbine’s functioning condition. Because they must endure extreme temperatures and atmospheric changes, it is essential that they be made from durable materials. Capital parts can include:

-Compressor Blades and Stator Assemblies


-Shroud Blocks

-Combustion Liners

-Combustion Baskets

-Inlet Guide Vanes

Consumable Parts

Even the smallest gas turbine parts play an important part in the functioning of the whole. For that reason, turbine parts builders put serious effort into ensuring that every bolt, lug, seal, and washer is capable of serving its purpose. Even though they are not as visible or as expensive as capital parts, they can also be reverse engineered to fit perfectly, avoid delays, and maintain the quality of the entire turbine.


Regular maintenance is the key to keeping your turbine’s parts from wearing out and requiring replacement in the first place. As expensive and inconvenient as some inspections and preventive repairs might be, damage and wear to a machine causes far more downtime and can even put workers in danger. A great gas turbine parts and repair company will work with you to provide speedy quality inspections and efficient repairs that fit into your facility’s schedule.
