Technological firing appliances for flue gas generators and drying facilities

By some types of industrial and agricultural drying facilities TÜKI is generally using monoblock gas or oil burners.

Such thermogenerators operating with one or two compact burners are primarily operating in brick and tile industry and these facilities were manufactured already in the years of 70-ies. The flue gas of these burning appliances is mixed with secondary air in its internal chamber in order to generate the required temperature of flue gas/air mixture.

By a special version of this concept is a relatively small capacity design, where series manufactured furnace burners are used. The combustion process takes place with perpendicular flame axis to the air to be heated, insulating and protecting the part of the volume where combustion is going. Many of such facilities were used for fluorescent lamp technologies.

Similar solution is applied by combustion chamber of flue-gas generators with ceramic lining too. But by these mentioned facilities because of the given technical features much higher flue-gas/air mixture temperature can be reached (max. 1400 °C). Such flue-gas generators can be applied in cement industry for drying of clay, for firing of rotary drum furnaces for alumina production and for drying of sugar beet in sugar industry.

Ejector operated umbrella type burners were primary used for firing of agricultural drying facilities consisting of 250 kW capacity prefabricated module units in accordance with the required capacity demand and space requirements. These appliances can be used on natural gas, PB resp. on propane gas firing mounted both in the suction pressure duct of drying air.
