FIELD: fuel.
SUBSTANCE: invention relates to removal of solids and other contaminants from flue gases, produced during fuel combustion. Method of reducing emissions during fuel combustion, produced under operating conditions in non-stationary state in fuel combustion system, having gas passage path, which passes from fuel combustion chamber through spraying drier-absorber to bag filter, located downstream of spraying drier-absorber, wherein method includes: admixing of calcium hydroxide dry powder to carrier gas into gas passage path in input position, located downstream of fuel combustion chamber and upstream of bag filter, spraying of water into carrier gas in spray drier-absorber for moistening and carrier gas temperature reducing and calcium hydroxide powder deposition in bag filter for precipitate producing on filter, which reduces emissions during fuel combustion, wherein temperature in spray drier-absorber is less than 220 °F.
EFFECT: removal of solid particles and other contaminants from flue gases produced during fuel combustion.
