Abstract:

As a new type of cheap clean fuel with high calorific value prepared by raw coal or pyrolyzed biomass， semi-coke is widely used in chemical metallurgy and other fields. The efficient and clean combustion of the solid fuel with semi-coke as its main component is highly environmental-friendly and economic， which contributes significantly to the energy conservation，emission reduction and economy development of China. The progress made in semi-coke fuel is reviewed. The technical route and study outcomes of pure semi-coke combustion verify the feasibility of its industrialization. To analyze the co-combustion of semi-coke with other combustible substances， the feasibility of semi-coke co-combustion is verified on a 660 MW supercritical boiler under the condition that the mass fraction of semi-coke is 50%. To analyze the application of semi-coke co-combustion in other fields， the economy and environmental benefits of semi-coke fuel applied in household burners are verified. The pollutant emissions， combustion stability， calorific value， comprehensive combustion efficiency， economic and environmental benefits of semi-coke fuel are evaluated comprehensively， then the development directions of semi-coke fuel are analyzed and summarized. Finally， based on the problems existing in current researches， the future research directions of semi-coke are discussed， which provides a reference for further study in this field.
