Biomass fired boiler supplier in South Africa
ZBG has developed a water cooled vibrating grate for biomass combustion which can be applied for a fuel input up to 280 MW. Grate firing requires less fuel preparation. The fuel is used as it is, i.e. there is no step between the forest or the farmer and the plant. Consequently, the fuel handling and the preparation equipment are substantially reduced compared to burner operation.
Biomass fuel types can be used in biomass fired boiler in South Africa
Due to the different ways of leading the fuel into the furnace and the different combustion air systems, there are two different types of biomass grate boilers, one type for straw-like fuels tied in bales and another type for other higher density biomass fuels like wood chips using air-swept spreaders.
In cooperation with the South Africa Company, ZG is to install the steam generator in the first straw biomass fired power plant in South Africa which will supply process steam and electricity to a nearby process installation as well as district heating to one city and electricity to the grid.
