What are the problems with biomass fluidized bed gasifiers?
The issue of tar treatment: the tar produced during the gasification process can easily clog pipeline valves. Therefore, it is necessary to handle the tar produced during the gasification process properly.
Reply 1#: Standing in the East, based on an analysis of the advantages and disadvantages of existing household-type upward-flow biomass gasification furnaces, and addressing the common issues such as low content of combustible components in the generated gas, high levels of tar and dust, and low calorific value of the gas, a redesigned air supply system was developed, along with a steam-based circulation reaction system. Additionally, a small-scale purification device with a simple structure that is easy to use was designed to minimize tar and dust formation during the gas generation process.

I’m very interested and would love to hear it and discuss it with everyone.
Biomass has a low energy density, especially straw. The tar content is high, and the calorific value of the gasified gas i is also low (with air); the organic silicon content in the gas affects its usability.

Reply to 2# ycy4792328: It’s so mysterious; in biomass gasification, attention needs to be paid to the treatment of tar and alkaline compounds. 1. The high ash content in the gas results in a large amount of slag in the tar, making it impossible to use the tar. 2. The volume of tar-containing wastewater and the difficulty of treating it increase. 3. The high carbon content in the ash reduces the conversion efficiency.
Reply to 9# xueluwinner: In fact, one can refer to the process flow of gas stations when handling this matter. It still has similarities to the purification process at gas stations.

Studying~! I am focused on promoting biomass energy~ Please give me your guidance:):):):)
