Novel tar-free stove integral gasifier

Abstract

The invention relates to a novel tar-free stove integral gasifier, comprising an updraught gasifier body provided with a high temperature cracking burner and an annular tar cracking unit. The central portion of the updraught gasifier body is equipped with a blanker, the bottom of the updraught gasifier body is equipped with the annular tar cracking unit and a ventilation pipe II, and one side of the updraught gasifier body is equipped with an air inlet pipe. The annular tar cracking unit is communicated with the air inlet pipe, and is provided with a dried layer, a dolomite layer and a charcoal catalytic pyrolysis layer from top to bottom. The inner wall of a gas stove is arranged at the outboard of the high temperature cracking burner, a taper fire-resistant air distribution ring is arranged at the bottom of the high temperature cracking burner, and a trumpet-shaped air pipe is arranged at one side of the bottom of the high temperature cracking burner. The taper fire-resistant air distribution ring is provided with a stove core. An infrared screen and an exhaust pipe are arranged on the top of the stove core, and a fuel-air mixing chamber internally provided with a ventilation head is arranged vertically below the stove core. The ventilation head is communicated with the ventilation pipe II through a ventilation pipe I. According to the invention, the purpose of sustainable combustion by one charging and no discharge of tar can be achieved.

Description

technical field [0001] The invention relates to a gasification furnace, in particular to a novel tar-free gasification furnace integrated with stoves. Background technique [0002] At present, the energy of biomass comes from solar energy, which is an important renewable energy source. Its efficient application will play an important supplementary role in improving my country's energy structure and sustainable development. my country has a large variety of biomass energy, and the available resources are also quite rich. Taking straw as an example, there are 1 billion tons in the country, and 650 million tons can be used for energy purposes. At the same time, biomass gasification can reduce the greenhouse effect caused by fossil energy consumption, which is of great significance to the long-term development of human beings and the living environment in the future. Under the guidance of the country's strategy of building a resource-saving and environment-friendly society and...
