Fewer parts and new motor technolo- gy increase the reliability and efficien- cy of the overall conveyor system. A permanent magnet motor specifical- ly designed for mining applications is a core element of this system that contributes to its reliability and abili- ty to perform in the most challenging environments. The gearless conveyor drive system eliminates the gear b ox f ro m t h e drive. This reduces the number of main wear parts, so less maintenance is needed, and lengthens the lifespan of the equipment. The expected lifes- pan for the drive train increases by more than 10 years when compared to traditional geared systems, to a pro- jected in service life of 25 years, noted the manufacturer. Other advantages include a consider- able reduction in the drive system's footprint, so it can be installed in smaller spaces, less weight and a reduction in the instrumentation required to operate the system. The gearless drive design is also more energy efficient, requiring less pow- er, and operates more quietly, thus reducing noise emissions. The operational data from a pilot project in Germany demonstrates the advantages of the gearless solution with less components. A gearless solu- tion is more reliable (with a 50 percent lower failure rate) and requires less maintenance. It is meeting eco design and energy performance requirements according to international standards to support mine site's environmental approvals or certification. The new drive also consumes 5 percent less energy than the other installed drive. The onsite team was impressed with ABB's quick and flawless project com- missioning. The operations and main- tenance team also found the new sys- tem to be easy to learn, understand and use, without any major difference in operation or handling when compared with the existing systems/technology. ABB, www.abb.com Babcock & Wilcox's (B&W) electrostatic precipitator (ESP) technologies deliver maximum particulate removal effi- ciency with proven reliability and reduced operating and maintenance costs. Engineered upgrades, quality com- ponents and replacement parts, and aftermarket services help keep existing ESPs running efficiently and effectively, regardless of OEM, according to the company. B&W has extensive experience with both dry and wet tech- nologies, and have installations in a wide range of applica- tions, including cement, power generation, waste-to-ener- gy, chemical, oil and gas, pulp and paper, metals/steel and others. Dry ESP. Regardless of the application, B&W's latest dry ESP design provides many advantages, including: • High efficiency. • High temperature capacity. • Wide capacity range. • Low maintenance. • Quality mechanical and electrical components for long life. • Advanced controls and software for optimum operation. Wet ESP. For industrial installations, the wet electrostatic precipitator provided by B&W offers highly efficient con- trol of submicron particulate, heavy metals, acid mists and condensed metal fumes and organics. For utility and power generation applications, there has been renewed interest in the use of wet ESPs to control selected emissions, espe- cially sulfuric acid mist (H2SO4) and fine particulates. Features and benefits of B&W's wet ESP system includes: • Low operating and maintenance costs. • Ultra-low particulate (solids, mist and fine particulate) emissions. • Hazardous pollutant reduction. • Optimized system design for sorbent injection technol- ogies. • Total system capability for integration with other pollu- tion control devices. • Well suited for new boiler installations as well as retrofit applications.
