A combustible producer gas composed of H₂, CO and CH₄ could be obtained by the thermal-chemical conversion of biomass. However, a large amount of particulate matters including tar generated causes the mal-function of turbines and engines or the fouling of pipelines. In this study, a wet scrubber using the soybean oil and bag filter were installed, and the removal efficiency was investigated. Hydrate limestone and wood char base activated carbon were pre-coated on the filter medium to prevent clogging of open pores. The removal efficiencies by the bag filter were 86 and 80% for the hydrated limestone and activated carbon coating, respectively. Overall, the collection when using a series of oil scrubbers and bag filters were 88%, while 83% for the filter coating material.

This study was conducted to develop a system that processes harmful gases and dust, which being generated in the production of micro-inorganic fabric. This can be obtained by melt spinning raw materials such as agalmatolite, fluorspar, limestone, silica under high temperature at $1500-1600^{\circ}C$ in a glass recuperator using a dry method by Cyclone Reactor or Envelope Type (ET) type Bag Filter. If the number of the members of Korea Glass Industry Association reaches up to 45, the damage of the harmful gas being generated in recuperator should not be small. In addition, research of existing facilities showed the most of harmful gas treatment facilities which adopt wet treatment or semi-dry treatment process. This was caused the problems for wastewater and the second pollutive materials. Moreover, in the dust collecting facility behind recuperator, it is also problematic that electric dust collector requires enormous initial investment. We have researched various methods to show both economic and efficient new processes for the preventive facilities of recuperator. As the result of the experiments, the removal efficiencies of HF and SOx were 99% and 87%, respectively. Although it was insignificant reaction, a pretty much interesting result that NOx showed an absorption reaction with $Ca(OH)_2$(removal efficiency was more than 25%) was obtained.
