Introduction

Twin Fire Fixed Bed Gasifier

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.

Take 5MW Biomass Wood Pyrolysis Gasification Co-generation of Electricity, Carbon, Liquid and Thermal System As An Example for Benefit Analysis
