20T Coal-fired boiler pulse bag dust collector is a kind of equipment specially used to filter the particles in

the flue gas of coal boiler, its main functions and characteristics are as follows: processing

air volume: according to the boiler model, combustion mode and working condition, it can

reach tens of thousands of cubic meters per hour.
Filter area: from a few square meters to hundreds of square meters, directly affect the dust

removal effect.
20T Coal-fired boiler pulse bag dust collectorFiltration efficiency: usually more than 99.9%,

the highest can reach 99.99%, to ensure that most of the dust and harmful substances are

effectively removed.
Filter bag material: Commonly used materials include polyester fiber, polypropylene fiber,

glass fiber, etc., with high filtration energy and long service life.
Cleaning method: including mechanical vibration, pulse blowing, reverse blowing, etc., among

which pulse blowing cleaning method is widely used.
Matters needing attention
Flue gas temperature control: strictly control the fluctuation of flue gas temperature to prevent

damage to the filter bag.
Pre-coating work: Pre-coating work of filter bag before boiler ignition to prevent oil mist from

adhering to filter material
Bypass protection: Set the flue gas bypass pipe to protect the dust collector from damage

under abnormal conditions.
Application and maintenance
Widely used: coal-fired boiler dust collector is widely used in the flue gas purification treatment

of various coal-fired boilers.
Regular maintenance: It is necessary to regularly clean the filter bag and check the electric

field structure to ensure the normal operation and efficient dust removal of the dust collector.
In summary, the dust collector of coal-fired boiler is one of the key equipment of flue gas

purification treatment of coal-fired boiler, and its efficient and stable dust removal performance

is of great significance to protect the environment and meet the emission standards.
