Combustion tests with fuel blend of bagasse and rice husk were done in a CHP boiler in the Mekong Delta. Both fuel blend preparation and the combustion test with fuel blend were highly successful. The test extends use of the mill's boiler facility for electricity production to all year round by eliminating enforced closure during the summer months.
The typical Vietnamese biomass materials are harvest and food processing residues of rice, sugar cane, wood, coffee and coconut. Most of these can be used as biomass fuel. The overall production potential for solid biomass in 2010 was 104.4 million tonnes (374 TWh), with the share of agrobiomass by-products at 70% and of wood fuel at 30%.
The major obstacles to investment in biomass power plants are the low price of electricity and the lack of reliable biomass supply chains.
The project (Development and demonstration of multi-fuel supply chains for power plants and industrial boilers in Vietnam) was realised through collaboration between VTT and the Institute of Energy in Hanoi.
