Companies that generate a large amount of wood ash will need an industrial process to agglomerate the ash and lower its reactivity, because untreated ash is a dust hazard for workers and is difficult to spread evenly on forest soil. In addition, untreated ash can cause burning damage to vegetation owing to its alkalinity and rapid release of salts. Production of large amounts of wood ash agglom...

When waste heat is not utilized, cooling of flue gases in special cooling chambers becomes necessary, if the dust':'collecting and associated equipment is constructed of metal. The two most common methods of cooling are by dilution with ambient air, and by evaporation of water in the gas stream. Usually, they are combined. Load sharing depends largely on acceptable visibility of stack effluvia ...

influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.observations show that without a vent hood, there is a downward gas flow in theflu...

The research presented by the authors in this paper focused on understanding behavior of mercury during coal combustion and flue gas purification operations. goal was to determine temperature emissions limits for lignites energy sector. examined process sorption from gases using fine-grained organic materials. main objectives study were recommend a low-cost adsorbent such as coke dust (CD), cor...
