Suggested Maintenance Log Program - National Board

A separate log sheet is suggested for each period. The log sheets can be filed in a loose-leaf binder, and should be retained as a permanent maintenance record. The log sheets can be used as a handy check-off system when establishing a facility maintenance program. In all cases the equipment manufacturer's recommendations should be followed.

Kraft Process - an overview | ScienceDirect Topics

The increase in back-pressure power generation will reduce purchased power. Some additional fuel will be required because of the increase in boiler heat demand. However, this will be offset by the electrical power savings. Capital costs for this project will include low-pressure steam piping, valves, and a temperature control system.


V88A (24 volts coil) diaphragm gas valves which are piped in parallel. The minimum input is controlled by an orifice plug installed in a coupling in the by-pass piping (low fire valve piping), sized for approximately 1" w.c. manifold pressure at low fire natural gas (2" w.c. if propane gas). When the

Cavitation - Wikipedia

Cavitation is a phenomenon in which the static pressure of the liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid.When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery. These shock waves are strong when they are very close to the
