The shank's geometry is equally significant. It often features a Morse taper, a standard system, which allows for secure and quick attachment to the drill rod or chuck. The thread design on some shanks enables a screw-in connection, ensuring a tight fit and preventing slippage during operation The thread design on some shanks enables a screw-in connection, ensuring a tight fit and preventing slippage during operation
Dry FGD systems, on the other hand, use a solid sorbent, like limestone or lime, to react with the SO2. The resulting compound is then removed from the gas stream through a filtration process. Although less efficient than wet FGD, it is more suitable for smaller installations due to its lower capital cost Although less efficient than wet FGD, it is more suitable for smaller installations due to its lower capital cost
La recinzione in catena è composta da un sistema di sezioni metalliche, generalmente in acciaio, che formano una rete intrecciata. Queste sezioni possono essere installate in modo lineare e sono supportate da pali verticali che ne assicurano la stabilità. Inoltre, la superficie delle sezioni è spesso zincata o rivestita per resistere agli agenti atmosferici, prolungandone così la durata.

Precision. In general, machined springs can be made to precise dimensions more easily than wire springs. Both wire wound and machined springs readily offer a precision of 10%. Machined springs can offer 1.0% precision. Wound springs can too, when statistical methods are used for selection. A finer precision of 0.1% is probably not available from wire wound springs and only available from machined springs using post-processing techniques.
