Abstract:
The main combustion process should be carried out in the regime of a fixed, forced ventilated bed for the efficient combustion of biofuel with low-melting ash in boilers with furnaces with a small height. After a certain period of time, a bed must be transferred into a state of turbulent fluidization, and then returned to its original state. So, the objective of the present work is to study the process of pellets combustion in such a bed (let’s call it a pulsating bed). The suggested technology of combusting ensures prolonged steady combustion of fuel with moderate carbon monoxide emissions. Combined coal waste and straw pellets combust more stable with less carbon monoxide emissions than straw pellets. Preliminary torrefaction does not influence the stability of combustion, but allows reducing carbon monoxide emissions from the combustion of combined coal waste and straw pellets. Production of coal-straw pellets can apparently be considered as a new variant of the organization of coal and biomass co-combustion; and in the case of pellets torrefaction, it allows producing water-resistant fuel suitable for use not only in electric power stations, but also in small boiler-houses.
