Problems solved by technology

At present, the way of using biomass power generation is mainly direct combustion. This direct combustion method is similar to the traditional coal-fired power plant. Its minimum installed capacity is 24MW, and the demand for raw materials is huge. Within a certain collection and transportation radius It is unable to meet the power plant's demand for raw materials, and more importantly, direct combustion still brings great pollution to the environment

Embodiment Construction

[0016] As shown in Figure 1, using gasification technology, agricultural and forestry wastes, including waste straw, sawdust, straw, rice husk, bagasse, etc., are converted into combustible gases close to coal gas through gasification devices. The main components of these combustible gases are CO, h 2 、CH 4 , CO 2 etc., calorific value is 1250kcal / m 3 Left and right, containing a small amount of tar at the same time, these combustible gases are removed from dust and tar by the gas purification device, and then sent to the gas internal combustion engine or gas turbine for power generation. .

Abstract

The invention relates to a method for generation by a biomass. The method utilizes the gasification technology, which converts the forestry and agricultural residues comprising wasted straws, sawdust, haulms, rice husks, bagasse, etc. into the flammable gas approaching the coal gas; after the dust and the tar of the flammable gas is removed by a purifier, the flammable gas is conveyed in a gas internal combustion engine or a gas turbine for generation. The invention has strong raw material adaptability, can dispose the biomass raw material of different types, and has the advantages of large production intensity, high gas heat value, little tar content, high gasification efficiency, strong load adaptability, easy start and stop, large adjustable range, stable operation, extremely high flexibility in scale. Furthermore, the generation scale depends on the quantity of the raw material and the requirement of the power, and can be designed and matched according to the requirement of the user.

Description

technical field [0001] The invention is a method for utilizing biomass to generate electricity. Background technique [0002] With the continuous progress and development of society, the extensive use of conventional petrochemical energy has brought about increasingly serious energy crises and environmental pollution. How to find alternatives to conventional fossil energy and reduce the discharge of various harmful wastes is a very urgent problem to be solved today. Various biomasses (including agricultural and forestry wastes and industrial wastes) are clean and renewable energy sources, and using these biomasses to generate electricity is an effective way to solve the above-mentioned problems. At present, the way of using biomass power generation is mainly direct combustion. This direct combustion method is similar to the traditional coal-fired power plant. Its minimum installed capacity is 24MW, and the demand for raw materials is huge. Within a certain collection and tr...
