Advancing grate-firing for greater environmental impacts and efficiency for decentralized biomass/wastes combustion
Abstract
Biomass power is an important routine to source more energy needs from renewables and to mitigate global warming. This paper presents an overview of all the key technologies currently used for direct biomass co-firing for combined heat and power production, among which grate-firing is regarded to well suit decentralized biomass and municipal/industrial wastes combustion. This paper discusses with concrete examples how to advance grate-firing for greater efficiency and environmental impacts, e.g., use of advanced secondary air system, flue gas recycling and optimized grate assembly, which are of great interest and relevance for further development of this technology.
