Considering the disadvantage of the present home and aboard biomass gasifiers, a new design was conducted to improve the current conditions such as low combustion, high tar and dust, low heat value and so on. A suite of gasification was achieved to decrease tar, sulfur and dust during gasification process. The developing system provides a feasible strategy for improving and developing gasifier equipment. The improved gasifier equipment includes gas generator, high temperature pyrolysis apparatus, the first dust filter, the second dust filter, heat-cold exchange apparatus, washing apparatus, motive power apparatus, tar removal apparatus, and sulfur removal apparatus. The harmless combustible gases enter the gas container, and go through a dedicated pipeline, and then the gas was delivered to the house for coking, heating or generating electricity. Up to now, the improved gasifier equipment has been successfully applied to some communities in Qinghai and inner Mongolia of China. Implications of the improved gasifier equipment is improving human health, reducing fuel consumption, deforestation and global climate change. It was found cost-effective and renewable in nature and suitable for both urban and rural areas, especially in the Qinghai-Tibetan Plateau because of the anoxia. The study has applied the patent of the State Intellectual Property Office of the People's Republic of China (Patent number: 201020192115.2). The product has produced by Lanzhou MinSheng straw liquefied gas stove Co., LTD, Gansu, China.
Key words: Biomass gasification, improved design, gasifier equipment, renewable energy, Qinghai-Tibetan.
