General information about the DN smoke exhauster: Unilateral absorption the Case spiral rotary Back the bent shovels the Number of shovels 16 Direction of rotation - right and left. Is defined from the engine. Purpose of the DN smoke exhauster: The DN smoke exhauster is intended for suction of combustion gases from fire chambers of the boiler installations or units equipped with effectively operating systems of a zoloulavlivaniye and also for suction of combustion gases from fire chambers of oil-gas boiler units. The smoke exhauster are calculated on a long operating mode indoors and in the open air in the conditions of a temperate climate. The maximum temperature of combustion gases on an entrance in the smoke exhauster is not above 200 °C. Temperature in flowing part of the smoke exhauster is not below -30 °C. DN smoke exhausters, general information
DN smoke exhausters (or fans of smoke removal of DN) are centrifugal tyagodutyevy cars of unilateral absorption. Are applied to absorption of gaseous products of combustion of fuel from fire chambers of boiler installations and units, oil-gas boiler units. Are established behind the boiler unit, for and in front of smoke exhausters compensators are installed. Differ from VDN fans in more dense walls of a snail that guarantees durability of cars. Shovels of DN smoke exhausters are built up by a firm alloy for protection against abrasive influence of particles of ashes. Productivity of different models of DN smoke exhausters from 5102 to 143000 m? / h. Are applied as separately, and in a complex with ventilating system.
General technical characteristics of DN smoke exhausters: the spiral rotary case, absorption unilateral, the number of shovels 16, the direction of rotation can be right or left and is defined from rotation of the engine. If to take a detached view of the DN smoke exhauster of the electric motor, then the left rotation of driving wheels - clockwise. Right rotation the return. Designations: Д - the smoke exhauster, N - shovels are recurved. Figures designate diameter of the driving wheel (decimeters).
