DPCleanTech Group Ltd., Copenhagen, Denmark, announced the completion of the first high temperature high pressure biomass power plant, which is specifically designed for the simultaneous combustion of all forms of coconut waste (husk, shell, bunch, fronds, leaves, trunk) as well as “conventional” biomass as wood residues, rice husk, etc. to produce electrical renewable energy, DPCleanTech says.
In early April, the Mahachai Green Power Company and plant in Samut Sakhorn Province, Thailand passed the 24 hours full-load test, thereby obtaining the necessary permit for entering into commercial operation by feeding 8MWe into the national PEA grid.
This 9.5MWe HPHT project represents a significant technological milestone in the combustion of complex, tropical biomass fuels, the company says. These fuels were long considered as too difficult to exploit for renewable energy.
Using corrosive fuel combustion and specifically designed technical solutions, including a modified Water Cooled Vibrating Grate, DPCleanTech has successfully achieved the combustion of all coconut waste residues.
Power generated by the plant will be fed into the public PEA grid, and any remaining ashes will be used as fertilizer for farming or filler material for construction. The project will create a substantial amount of local employment.
The Mahachai plant is optimised to handle different types and forms of coconut biomass waste as well as other types of biomass such as wood residues. It is designed to consume up to 323 tons/day of moist fuel and to operate with an availability of more than 7,900 hours per year.
The plant was delivered to the owners on an EPC basis, which allowed DPCleanTech to ensure that the design was optimized and integrated into the whole solution.
