Embodiment 1

[0027] Example 1 Preparation of biomass energy blocks or granules

[0028] Taking straw as an example, the straw is compressed into energy blocks of a specified size by a compressor, or the additives described in Table 1 are added to the straw according to the formula in Table 2, mixed well, and compressed into energy blocks of a specified size by a compressor.

Embodiment 2

[0034] Example 2 Biomass Gasification Power Generation

[0035] Example 1 The energy block passes through the combustible gas combustion section with an oxygen-rich condition higher than 1.2 atmospheres and a temperature of 1100-1200°C, and falls to the biomass gasification section after instant drying and preheating;

[0036] In the biomass gasification section, the working conditions are isolated from air and at a temperature of 900-1000°C, the energy blocks or particles are gasified into combustible gas;

[0037] The combustible gas directly enters the combustible gas combustion section for combustion, and the combustible gas directly enters the combustible gas combustion section for combustion, so that the combustible gas combustion section reaches a temperature of 1100-1200°C;

[0038] The heat generated in the biomass gasification section heats the water into steam;

[0039] The steam drives the screw expander, and the screw expander directly drives the generator to gen...

Abstract

The present invention relates to the field of clean energy, in particular to a method for generating electricity by biomass gasification, which includes the following steps: compressing biomass materials into energy blocks or granules through a compressor; Oxygen-enriched at 1.2 atmospheres, the combustible gas combustion section with a temperature of 1100-1200°C is instantly dried and preheated and then falls to the biomass gasification section; in the biomass gasification section, the working condition is to isolate the air and the temperature is 900-1000°C Next, the energy blocks or particles are gasified into combustible gas; the combustible gas directly enters the combustible gas combustion section for combustion, making the combustible gas combustion section reach a temperature of 1100-1200°C; the biomass gasification section or / and combustible gas combustion The heat of the section heats the working medium; the working medium is sent to the power generation device to generate electric energy. The invention significantly improves the utilization rate of the calorific value of biomass combustion, reduces environmental pollution and obtains considerable economic benefits, and has good application prospects.

Description

technical field [0001] The invention relates to the field of clean energy, in particular to a method for biomass gasification power generation. Background technique [0002] Biomass mainly refers to lignocellulose (referred to as lignin) such as straws and trees other than grains and fruits in the process of agricultural and forestry production, scraps of agricultural products processing industry, agricultural and forestry wastes, and livestock manure and waste in the process of animal husbandry production. substances, etc. [0003] Biomass energy has always been an important energy source for human survival. It is the fourth largest energy source in the world's total energy consumption after coal, oil and natural gas, and occupies an important position in the entire energy system. my country is extremely rich in biomass energy. The annual output of crop straw in the country is about 600 million tons, and about 300 million tons can be used as fuel, which is equivalent to ab...
