DP CleanTech selected to supply boiler and flue gas cleanup to Thai EfW project
China-headed biomass combustion technology providers DP CleanTech Group has recently announced that it has concluded a contract with A2 Technologies Co. Ltd, a subsidiary of Super Energy Corp PCL, a leading renewable energy provider in Thailand. The energy-from-waste EfW project in Nongkhai province will process refuse-derived fuels (RDF) to produce 6 MW of electricity to the grid.
According to a statement, DP CleanTech will provide the engineering, supply, installation, and commissioning of the boiler and flue gas treatment system for the plant, which is expected to enter into commercial operation in mid-2022. The value of the order has not been disclosed.
We are delighted to be working with the Super Energy Corporation, a highly successful and progressive company which has already made its mark with solar energy in Thailand and other SEA countries and is now working towards a target of delivering over 50MW of energy from waste materials as a key part of their renewable portfolio; DP and Super Energy are confident in the rapid growth of RDF production and processing as an essential component of the renewable industry in Thailand, and that the Nongkhai plant will pave the way for similar projects, said Simon Parker, CEO of DP CleanTech.
Increase renewables and reduce landfill
As part of the new Thai National Power Development Plan (PDP) for 2018-37, 30 percent of total energy production will be produced by renewable energy by 2037 – a doubling from the current 14.5 percent.
This has been accompanied by a move to reduce some of the previous barriers and complications to investor participation in waste-to-energy power projects, enabling progressive Thai companies such as Super Energy to take the lead in development.
Thailand’s renewable strategy is partially driven by the need to address the growing volumes of solid waste, forecasted to grow from an estimated 40 662 tonnes per day in 2008 to 42 900 in 2023.
For the past 40 years, over 50 percent of this has gone directly to landfills, creating a huge and developing problem for the future.
RDF a challenging fuel
RDF can be produced from these waste materials, however, its successful use as a fuel is contingent on improved waste separation practices; and on overcoming economic, environmental, and technical issues.
To date, the difficulty around these problems has limited development to around 20 plants, mainly cement plants, in Thailand using RDF fuel, with some experiencing operational problems.
In terms of technical issues, RDF fuel qualities are highly challenging for managing equipment corrosion and emissions. If not addressed, these problems can render plants economically unviable.
Well established in Thailand
According to DP CleanTech, it has proven technology and longstanding design and operational expertise in designing boilers and FGT systems for highly corrosive biomass fuels.
The company has also been involved in the Thai biomass industry for many years and has been formally recognized for its innovative practices and quality solutions in the Thai market.
This latest contract paves the way for DP to lead the development of RDF-related projects in overcoming technology issues and to help meet Thailand’s 2037 PDP target of 20 766 MW out of 56 431 MW (about 37 percent) to be delivered from renewable sources.
In addition, DP CleanTech has technologies for organic waste, landfill waste, and biomass waste, thus providing a complete portfolio for waste management.
