Why Are Ceramic Multi - tube Dust Collectors Still the Preferred Choice for Biomass Boilers?

Although bag filters dominate modern air pollution control, in one application area, ceramic multi - tube dust collectors still perform excellently: biomass boilers with high humidity and high spark content.

At Haina, we have improved this classic technology into a precise pre - treatment solution. Our ceramic multi - tube dust collector (Patent No.: ZL2014 2 0336749.9) has a dual function:

Efficiently remove coarse particles (>5μm)
Act as a key spark arrester to protect downstream bag filters from being burned through
Our design is equipped with perlite insulation material in the inlet area to prevent dust re - entrainment and maintain thermal stability. For systems integrated with SCR denitrification devices, 100 - millimeter external aluminum silicate insulation material ensures a safe operating temperature and protects workers.
More than 9,800 units have been installed nationwide, and with the increasing demand from palm shell power plants in South America and rice husk facilities in Africa, Haina continuously proves that sometimes, the best innovation lies in perfecting basic technologies.

Professional Tip: Pair our ceramic dust collector with an online ash - cleaning bag filter for optimal performance in biomass operations with fluctuating loads.
