A study on air atomisation for the diesel oil system of Vung Ang 1 Thermal Power Plant
Abstract
At coal-fired thermal power plants, diesel oil (DO) is used during the startup/shutdown of the unit or in case of unstable combustion mode. Each restart of the boiler consumes more than 500 tons of DO, equivalent to VND 12 billion.
To lower power production costs and maximise profits, the Operational Unit of Vung Ang 1 Thermal Power Plant, Petrovietnam Power Corporation have studied to apply air atomisation instead of the traditional steam atomisation for DO burners. The obtained result shows that the new method helps reduce DO consumption to less than 200 tons/start-up, contributing to lower production costs, maximise profits and especially to increase competitiveness in the electricity market.
