Biomass pyrolysis and gasification method

Abstract

The invention discloses a biomass pyrolysis and gasification method comprising the following steps of (1) carrying out pyrolysis transformation on a biomass raw material; (2) separating a solid-phase product from a gas-phase product; (3) cracking the gas-phase product generated after pyrolysis at the temperature of 800-950 DEG C; (4) lighting the gas and using the gas. In such a way, the biomass pyrolysis and gasification method has the advantages of wide raw material application range, little biomass ash generated in the transformation process, no primary energy with high cost, economical efficiency increment of energy utilization and the like so as to have wide market prospects on the aspect of popularization.

Description

technical field [0001] The invention relates to the field of energy, in particular to a biomass pyrolysis gasification method. Background technique [0002] Energy is the basis for the survival and development of modern society. The supply capacity of energy is closely related to the sustainable development of the national economy and is one of the foundations of national strategic security. China's current energy supply situation is grim, and the burden on environmental quality is heavy. Due to the dwindling reserves of fossil energy, large fluctuations in oil prices, concerns about energy security and global warming, the development of clean and renewable energy has become an urgent issue, and the new energy industry is showing high growth. According to the widely demonstrated industrial background and development overview of renewable energy, biomass gasification power generation represented by biomass energy, biomass hydrogen energy, and biomass green liquid fuel will b...

Problems solved by technology

[0006] 1. Burning coal, diesel, and natural gas consumes a lot of energy and is not conducive to environmental protection;

[0007] 2. The flue gas after combustion returns to the furnace through the waste heat utilization tube. The flue gas is not conducive to the full and uniform combustion of biomass, the heat generated is uneven, and the melting speed of the alloy ingot is slow, resulting in increased production costs;

[0008] 3. The temperature in the furnace cannot be accurately controlled;

[0009] 4. Biomass direct combustion will produce tar and other environmental pollution
