How To Increase Cooling Tower Efficiency?

Image
  cooling towers. A device for dissipating heat from processes such as water evaporation. In this article, we will introduce solutions for Increasing Cooling Tower Efficiency . Stay with us. The U.S. Department of Energy (DOE) is proposing to provide funding to the State of Arizona to replace parts of the heating, ventilation, and air condition system that have reached their expected useful life with more energy-efficient equipment at the Arizona State Veterans’ Home in Phoenix, AZ. Specifically, the cooling towers, condenser pumps, air dirt separator, interconnecting piping with valves and fittings, and the controls would be replaced. a cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely

DC and AC generators and its differences

Image
  In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. This article is about the types of generators and the difference between DC and AC generators . If you have any questions about the Diff BW AC and DC Generator , read this article to the end. AC generator is considered an electrical generator for converting mechanical energy into electrical energy. This energy is in the form of alternating current or alternative EMF. DC generators convert mechanical energy into DC electricity which is short for Direct Current. AC Generator vs Dc Generator AC vs. DC: T

Alternator and its types

Image
  An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. You must have heard the name of the alternator by now. A device that converts mechanical energy into electrical energy. In this article, we will introduce and review the types of alternators . Stay with us. Alternator Types 1.Diode Assembly DC, the current type used by car batteries, is converted into direct current by an alternator’s diode assembly (AC). The two-terminal diode assemblage works by allowing only one direction to flow the electricity generated by t

What are the differences between salient pole and cylindrical pole?

Image
  The magnetic path is characterized by poles, locations at equal angles around the rotor at which the magnetic field lines pass from stator to rotor or vice versa. The stator (and rotor) are classified by the number of poles they have. Most arrangements use one field coil per pole. Some older or simpler arrangements use a single field coil with a pole at each end. In this article, we will first introduce salient pole and cylindrical pole. We will explain the performance of each and at the end, we will examine the Difference between salient pole and cylindrical pole . Read this article.

industrial gearbox and its applications

Image
What is industrial gearbox ? An industrial gearbox is an enclosed system that transmits mechanical energy to a transmission unit. The system slows down the speed and torque of rotation. Industrial gearboxes are different from standard gearboxes, as the former needs a long, stable life and safety factor for most of the drives. To control speed and torque and convert it functionally, an industrial gearbox transmits mechanical power into a driving tool. In contrast to mass gearboxes, industrial gearboxes can handle multiple tasks at extremely high speeds over a long period. Read more  here What do you know about  industrial gearbox ? In this article, we intend to introduce the industrial gearbox and its applications. Read this article to the end. A transmission is a machine in a power transmission system, which provides controlled application of power. Often the term 5-speed transmission refers simply to the gearbox, that uses gears and gear trains to provide speed and torque conversions

What gases are used in air conditioning?

  You must be familiar with air conditioners. These devices are available in the form of air conditioners, splits, and air purifiers. In these devices, a kind of gas is used and it monitors their performance.   which gas is used in a c ? To answer this question, read this article and join us. Hydrochlorofluorocarbons (HCFCs): In the 1990s and 2000s, the CFCs were replaced with HCFCs (hydrochlorofluorocarbon) and the most common HCFC is “R-22”. R-22 is just slightly better than CFC as it contains chlorine. However, it is harmful to the environment and also has ozone depletion potential. Read more on this   website . Air conditioning (often referred to as AC, A/C, or air con)[1] is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other

Gas turbine components

  this article, we are going to examine gas turbines. After that, we will introduce and review   Gas turbine components . Join us. Energy security has become a significant concern for many countries around the world. Potential threats include geopolitical instability, fuel supply disruptions and surging fuel costs. High natural gas prices in Europe have impacted the economic viability of gas turbines with more than 20GW of combined cycle gas turbine capacity idled or planned for retirement. Despite abundant shale gas reserves, the U.S. has experienced regional price spikes from gas supply bottlenecks. In the Middle East where natural gas accounts for 60 percent of power generation, disruptions to the Arab Gas Pipeline have stressed electric power systems. The ULTIMATE program will develop and demonstrate ultrahigh temperature materials that can operate in high temperature and high-stress environments of a gas-turbine blade. Projects will specifically target gas turbine applications in

Detailed inspection of DC motors and components

  What is a DC motor?   How Does a DC Motor Work ? One of the types of electric motors is DC motors that play an important role in industrial parts. In this post, we will first provide a brief definition of DC motors and review   dc motor working principles . Then we introduce the   types of DC motor   and finally, we examine the DC motor parts. Stay with us. A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in parts of DC motor. Advantages and Disadvantages of DC Motors : here is a wide range of DC motors in different dimensions and sizes, suitable for different needs. Small ones can be used in toys, tools, and home appliances, and larger ones are used in the elevator and hoists and propulsion

Check industrial valves

Image
  An expansion valve is a device in steam engine valve gear that improves engine efficiency. It operates by closing off the supply of steam early before the piston has travelled through its full stroke. This cut-off allows the steam to then expand within the cylinder.   Types of Expansion Devices   are as follows: 1.Thermal expansion valves (TEVs) 2.Manual valves 3.Capillary tubes 4.Automatic valves read more  here Control valve: A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. You must have heard the name of industrial valves or seen them up close. Such as ball valves, expansion valves, etc. In this article, we will introduce control valves,  ball valve parts , and  types of expansion valves . Stay with us.
