The multicyclone is a passive flue gas cleaning element, utilizing centrifugal forces to remove particles from the flue gas flow. The bottom of the multicyclone is a hopper under which is a rotary valve for evacuating accumulated dust into an ash screw. The rotary valve is operated by a heavy duty gearmotor. Multicyclones are installed between the hot water boiler and draft fan. Multicyclones are delivered insulated.
Working principle of a multicyclone
Multicyclones are used to separate volatile ash, sooth and other solids from the combustion products (exhaust) of the solid fuel firing systems. They are used for both manually and automatically stoked boilers. Their size is chosen depending on the amount of exhaust to be cleaned, boiler output and fuel moisture content. In the bottom of the multicyclone there is an ash collecting tank or a rotor valve under which deashing transporters are installed. Openings for the flue channels are cut on site. Multicyclones are delivered insulated.
It is necessary to install a multicyclone to catch solid particles in the flue gases leaving the boiler. The MT-500 multicyclone consists of six 1D-2D elements and cleans the exhaust gases to the level prescribed for pellet boilers. After the multicyclone, the dust content of the flue gases remains <300 mg / Nm3. The maximum permissible operating temperature is 250 ºC. The multicyclone MT-500 is connected directly to the boiler flue. The Karl Klein ENG 8-32 smoke extractor is attached directly to the multicyclone, the operation of which is controlled by the PV 500 pellet burner according to the vacuum in the furnace. All connections must be sealed with either a gasket or heat-resistant silicone mastic. The multicyclone cyclone MT-500 is maintenance-free. The fly ash accumulated in the cyclone must be removed as necessary. Dimensions and working principle shown in the figure.
