1.3 Plant Background The Point Aconi Generating Station consists of a 172 MW CFB combustion unit, which burns a blend of petroleum coke and offshore coal of varying sulfur contents (2-6.5% sulfur content). The CFB technology utilizes limes...

AI summary The Point Aconi Generating Station uses a 172 MW CFB combustion unit to burn petroleum coke and coal, producing CFB residue. The residue is conditioned with water and transported to a landfill site. The landfill is 48.9 hectares, and separate silos are used for bottom ash and fly ash.

Generating Station Net Capacity 172 MW Generating station average capacity factor 0.88 Electrical output/energy output (efficiency) 34% Pet Coke Heating Value (low ash) 25,025 kJ/kg Offshore coal Heating Value (med ash coal) 20,882 kJ/kg 2...

AI summary The document presents technical data on the Point Aconi CFB generating station, including net capacity, efficiency, fuel heating values, sulfur content, and residue generation estimates for two fuel types. It includes tables and figures related to the station's operational characteristics and environmental impact.

Residue Management Operations Manual Date: July 2021 These tables reflect two possible sets of fuel characteristics available from blends of pet coke and coal. It can be expected that "low ash" blends will have less of an impact on the gen...

AI summary The document discusses residue management operations at a power generation station, focusing on fuel characteristics and their impact on ash generation. It outlines different fuel blends, capacity factors, and residue production rates, noting that actual capacity factors have been lower than expected due to increased renewable energy capacity.

2.5 Objective of Ash Diversion Ash reuse in the production of cement, concrete, and other building materials has been recognized as a possibility for Nova Scotia Power. A transition to higher use of renewable energy sources in North Americ...

AI summary Nova Scotia Power (NSP) aims to divert coal ash for use in cement and concrete production, leveraging the decline in coal use due to increased renewable energy adoption. NSP plans to continue using thermal energy sources through 2040 and sees the sale and export of coal ash as a significant opportunity.
