ABB Upgrade Orders In Brazil
Partnership with Wärtsilä anticipates improved Brazil power plant efficiency of at least 1% annually
ABB’s Turbocharging business unit received an order to upgrade 30 turbochargers in a series of power plants operated by Wärtsilä under O&M agreements. ABB said it has been working with Wärtsilä since early 2012 to create and pilot this service option.
The company said that going beyond an exchange of one like product for another, an upgrade improves engine performance by matching the latest turbocharger technology with an engine in an iterative process that ensures an ideal fit. Significantly, an upgrade also makes an engine more fuel-efficient, saving at least 1% in fuel annually, and in some cases even up to 3%, ABB said.
The modifications made in an upgrade also considerably reduce the exhaust gas temperature of the engine (-20 to -30oC), reducing the thermal load – the main factor affecting the deterioration of the engine – on the turbocharger and engine.
The new turbochargers are expected to run for about eight years.
