TFBG Introduction
POWERMAX
Twin-Fire Fixed Bed Gasifier (TFBG), developed and researched
independently by POWERMAX, is a high-efficient biomass fixed bed
gasifier that combines the advantages of traditional Updraft Fixed Bed
Gasifier (UFBG) and Downdraft Fixed Bed Gasifier (DFBG) and improves the
disadvantages of the two gasifiers.
| COMPARISON | ADVANTAGES | DISADVANTAGES |
| Traditional Updraft Fixed Bed Gasifier(UFBG) | High thermal efficiency | Dirty gas with much tar |
| Traditional Downdraft Fixed Bed Gasifier(DFBG) | Low thermal efficiency Clean gas with little tar | Low thermal efficiency |
| Powermax Efficient Twin-Fire Fixed Bed Gasifier(TFBG) | High thermal efficiency clean gas with little tar |
Suitable Fuel:
Briquettes fuels like wood chip, rice husk block, straw block, coal, etc.

Benefit analysis
The biomass gasification
polygeneration technology can efficiently transforms the biomass into
electric energy or thermal energy and simultaneously produce the biomass
charcoal and the biomass wood vinegar. The electricity generated can be
directly connected to the grid with a price subsidy of 0.75 yuan/KWH;
Biochar can be used in production, barbecue charcoal and carbon base
fertilizer and other products; The biomass extract obtained by
purification of wood vinegar is widely used in pharmaceutical and food
industries or as leaf fertilizer.
