Filter bags for power plants, baghouse by baghouse.
Coal-fired boiler baghouses most often use PPS filter bags, because PPS resists the acid and moisture in flue gas up to 190 °C. P-84 is used where temperature runs higher, and fibreglass suits reverse-air designs. Biomass boilers bring sparks and sticky ash, and ash handling uses polyester.
Media by baghouse
| Baghouse | Conditions | Media to evaluate |
|---|---|---|
| Coal-fired boiler | Acidic, moist flue gas, 130–190 °C | PPS, or PPS/P-84 blend |
| Boiler, reverse-air design | Hot flue gas | Fibreglass with finish |
| Biomass boiler | Sparks, sticky ash, moisture | PPS with spark protection |
| Ash handling and silos | Ambient, abrasive ash | Polyester |
This is a starting point. The final choice depends on measured temperature, moisture, gas chemistry and the cleaning system.
Things that shorten bag life here
- Oxygen content matters for PPS: high O₂ at high temperature oxidises it.
- Boiler start-ups below the acid dew point can wet and blind bags; pre-coating helps.
What Masturlal supplies

Questions, answered.
Which filter bags are used in power plants?
It depends on the baghouse. See the table above: each location has a different temperature and dust, so different media.
Does Masturlal supply plants outside India?
Yes. About 30–35% of turnover is exports, mainly to the Middle East, Bangladesh and Southeast Asia, with installations in 40+ countries.
