Main smoke pump DN-26,5õ2-0,62K with electric motor

Double-sided centrifugal smoke pump with back-bent sheet blades, designed for flue gas discharge from pulverised coal-fired steam stationary boilers at dry and wet ash collection and dustiness of the gas stream not more than 2 g/nm3, in gas cleaning systems of metallurgical plants and other industries at gas temperature up to 250 C. Smoke pump structurally consists of guide apparatuses necessary for regulating the parameters of operation, spiral casing, suction pockets, impeller, which serves to transfer energy to the flow from the drive motor and running gear. In the process of medium movement in the impeller, the flow is dynamically influenced by the leaf blades and is involved in rotational motion. As a result, the momentum of the transported medium changes and its potential and kinetic energy increases. The increase in flow energy is expressed as an increase in static and dynamic pressure.
