The ash disposal system utilizes a hydraulic analysis based on the following: Material : BBA Pressure gradient frictional head loss : 0.281 kPa/m @ Cw = 30% Concentration by mass, Cw : 20% – Capacity.
Pressure means the total load or force per unit area acting on a surface.
Pressure vessel means a vessel that may be used for containing, storing, distributing, transferring, distilling, processing or otherwise handling any gas, vapour or liquid under pressure greater than the atmospheric pressure and includes any pipeline fitting or other equipment attached thereto or used in connection therewith; and
Psig means pounds per square inch gauge.
Altitude means the vertical distance of a level, a point or an object considered as a point, measured from mean sea level (MSL);
True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.
