(GlobeNewswire) - Valmet and Urumchi Jinghuan Environmental & Energy Co., Ltd. have signed a contract regarding a delivery of two boiler plants fired with refuse-derived fuel (RDF) for a greenfield waste-to-energy plant in Urumchi, China. The new waste-to-energy power boiler plant will support the circular economy and supply electricity to the power grid.
The order was included in Valmet's third quarter 2018 orders received. The value of the order is not disclosed.
The waste-to-energy solution enables high overall efficiency with very effective heat and power generation. Installation of the boiler is scheduled to begin in March 2019. Heat and power production will start by the end of 2019.
"Valmet's CYMIC boiler technology offers the most reliable solution for RDF. We expect to achieve high economic efficiency with less need for maintenance and fewer production shutdowns," says Wang Haoyu, Deputy General Manager and Chief Engineer of the plant. "At first, we didn't believe that an RDF-fired boiler could be this large and efficient, especially for handling China's extremely demanding municipal solid waste. But after visiting Valmet's excellent RDF boiler reference in China, we are fully convinced. The tailor-made boiler design meets our expectations for size and parameters, and we believe it will help us to optimize the entire plant."
"This will be our largest waste-to-energy boiler delivery in China. Our waste-to-energy concept has been developed especially for power plants utilizing RDF. It offers excellent reliability and lifespan through Valmet's unique superheater design, even for demanding fuels. Utilizing waste in energy production enables significant reductions of CO2 emissions compared to fossil fuel-powered plants," says Jussi Sinisalo, Valmet's Vice President for Pulp and Energy in China.
Technical information about the delivery
Valmet's delivery includes the major parts of two CYMIC boiler islands, from fuel silo to boiler outlet. The boiler uses circulating fluidized bed technology.
The boiler plant will burn one million tons of RDF (produced from 100% municipal solid waste) every year. Natural gas is used only for start-ups. The chlorine and alkaline content in the RDF fuel is very high, but Valmet's circular fluidized bed technology effectively controls emissions and corrosion.
