At present, according to the report of the Electric Power Research Institute (EPRI), half of the forced energy storage and transportation loss in a power plant is caused by sewage erosion of the boiler. ABB has its own solution to this problem. According to EPRI's study, using effective control of the steam chemical reaction process, plant personnel can improve plant thermal efficiency and profitability and reduce maintenance costs. The agency is an independent not-for-profit organization that studies energy and the environment, and its members represent 90% of the power generation industry in the United States. The report shows that, in contrast, poor water vapor purity can lead to corrosion damage and waste deposition on major components, which can lead to damage to turbine blades in boiler and inlet pipelines, as well as accelerated fluid erosion. Generators may also suffer from the same problem. As a leading supplier of analyzer products, systems and solutions to the power, water and processing industries, ABB is helping to monitor and maintain the purity of water and steam in related businesses.
Auger Bit
The auger bit adds a long deep spiral flute for effective chip removal.
Two styles of auger bit are commonly used in hand braces: the Jennings or Jennings-pattern bit has a self-feeding screw tip, two spurs and two radial cutting edges. This bit has a double flute starting from the cutting edges, and extending several inches up the shank of the bit, for waste removal.
The Irwin or solid-center auger bit is similar, the only difference being that one of the cutting edges has only a "vestigal flute" supporting it, which extends only about 1â„2 in (13 mm) up the shank before ending.
The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch. For example, #4 is 4/16 or 1/4 in (6 mm), #6 is 6/16 or 3/8 in (9 mm), #9 is 9/16 in (14 mm), and #16 is 16/16 or 1 in (25 mm). Sets commonly consist of #4-16 or #4-10 bits.
