Power generation comes from a variety of heat-producing sources: oil, natural gas, nuclear, geothermal, wind, solar and of course, coal. The heat boils water and creates steam. The steam, under high pressure, spins a turbine. The turbine interacts with a series of magnets to produce electricity, which is transmitted as moving electrons through a series of wires to homes and businesses.
Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was 7.99 billion tons in 2010, and is expected to increase 48% to about 9.98 billion tons by 2030. Coal can be delivered by truck, rail, barge or ship, and some power plants are even situated near coal mines so coal can be delivered by conveyor systems.
Railways have existed in India since 1853, and several organizations have enforced standardization among the various railway systems over time. Since 1957, the Research Designs and Standards Organization (RDSO) has been the sole authority operating under the India Ministry of Railways. The latest rule to standardize Indian railways is the RDSO's G-33 Rev 1 Requirements. The "G-33" part of the title represents a mix of new and existing rules that are specific to Wagon Tipplers along the railroads.
FOR IMMEDIATE RELEASE: Pittsburgh, PA – Heyl & Patterson Inc., a world leader in thermal processing systems and bulk materials handling, has received a Golden Triangle Award from the International Association of Business Communicators (IABC) Pittsburgh Chapter during its annual competition.
Activated carbon is a form of carbon that is riddled with tiny pores that increase its surface area, making more of it available for chemical reactions. This porous, highly adsorptive material is used to remove color or impurities from liquids and gases, in the separation and extraction of chemical compounds, and in the recovery of solvents. In other terms, activated carbon is used in water filtration, gas purification, sewage treatment and metal extraction. It is most commonly found in the filters of aquariums, respirators and gas masks, and is used to treat poison following oral ingestion.
Bulk cargo is a commodity that is transported unpackaged in large quantities. The main purpose of bulk material handling systems is to transfer the material as quickly and cleanly as possible as it is moved from one place to another. Loading and transporting are just two stages in the process of transferring bulk materials from the producer to the consumer. When transporting by rail, they must be unloaded from railroad cars, which is usually done with rotary dumpers or turnover dumpers, which discharge loads parallel to the rails.
Coal-fired power plants continue to be the largest source of electricity generation in the United States, but their market share is declining. About 15 percent of the coal-fired capacity currently active is expected to be retired by 2040. Existing coal plants that have undergone environmental equipment retrofits will continue to operate throughout the projection, with natural gas, renewables and nuclear power steadily growing in the years to come. The American energy mix is changing, and the U.S. can learn from growing pains occurring on foreign soil.
Heat is generated by electrical equipment and industrial processes every day, unintentionally bleeding off into the atmosphere. This waste heat often involves the combustion of fuels, and occurs in the largest proportions from power stations, industrial plants and vehicle engines. It is inevitable that some of this heat will be lost, but much of it can still be utilized. It can be used for the majority of heating applications, but unlike electricity or fuel energy, it is impractical to transport over long distances.
The most difficult part of a drying process is material handling, and not heat transfer. For continuous drying of bulk solids, Rotary Dryers excel in their ability to handle a very broad range of materials regardless of their conveying and handling characteristics. Whether your process requires the drying of fine dusty powders, lumpy solids, sticky semi-plastics, pellets, agglomerates or even a mixture of all of the above, there is a Rotary Dryer that will accomplish the task successfully. Their ability to effectively process such a broad range of materials is what has earned the Rotary Dryer the nickname "workhorse of the processing industry."
The words "built to last a lifetime" are overused in today's world. There are few examples of products that actually hold true to that promise. One of the few is Hammerhead Crane 110 at the Norfolk Naval Shipyards, constructed by Heyl & Patterson in 1940 and instrumental in America's effort during World War II. More than 70 years after it helped build the fleet that won the war, it is still standing.
