Brazil promotes biomass power generation


The Brazilian state government of Sao Paulo has announced plans to build a new biomass power plant, which is expected to open in 2023.

Biomass energy has the characteristics of green, low carbon, clean, renewable and so on. In recent years, it has been widely used in the fields of heat supply, power generation and transportation, among which power generation using sugarcane residue is one of them. Brazil is one of the world's largest producers of sugarcane and has been actively using it to generate electricity.

Brazil legislated in 2017 to approve the national Biofuel Policy, which aims to increase the use of biofuels, including sugarcane, throughout the country, improve energy security and reduce greenhouse gas emissions. In 2020, Brazil generated 2.26 billion kilowatt-hours of electricity from sugarcane, accounting for 82% of the country's total biomass energy generation. Brazil's sugarcane industry association believes the country's biomass power generation capacity will grow by more than 55 per cent by 2030.

Sugar cane produces a lot of solid residue when it is processed into products such as sucrose or ethanol, and is often used as fertilizer. The new plant in Sao Paulo state uses biodigesters to turn some of the organic matter in the solid residue into biogas, and in the process produces methane that can be used to generate electricity. Power plants can use the technology to generate electricity all year round -- the distilled residue is not easy to store and can be used to generate electricity during the harvest season; The solid residue can be stored and used without seasonal restrictions.

Sao Paulo state is Brazil's leading sugarcane producer, producing about 54% of the country's sugarcane. Biomass now accounts for 25 percent of the state's household electricity, according to a report by the Sao Paulo Research Foundation. Experts believe that if sugarcane residue can be used more efficiently in the power generation process, this proportion will be greatly increased.

The Sao Paulo state government has long been committed to promoting the use of biomass energy through a number of initiatives. In 2012, Sao Paulo state launched the Paulista Biogas Project, emphasizing the use of the local sugarcane industry to promote biogas and biomethanes. In 2017, the state passed legislation to inject biomethane into public natural gas transit pipelines, requiring at least 0.5 percent of biomethane to be added to the pipeline and increasing the proportion over time.

With the continued support of the government, the local research institute has published an interactive map of biogas, biomethanes and electricity in Sao Paulo State, providing clear data for policy makers and investors to better develop and utilize biomass energy.

The generator set control module adopts the microprocessor-based

The generation principle of biomass synthesis gas: biomass raw materials enter the reactor of the gasification furnace, after being heated and dried, and then as the temperature rises, its volatile matter is precipitated and pyrolyzed (cracked) at high temperature. The pyrolyzed gas and production The substance undergoes a combustion reaction with the supplied air in the oxidation zone to produce CO2 and water vapor. The heat generated by combustion is used to maintain drying, pyrolysis and endothermic reactions in the lower reduction zone. The gas produced after combustion passes down the reduction zone and reacts with the high-temperature carbon layer (C+CO2=2CO, C+HO2=H2+CO) to generate biomass synthesis gas containing CO, H2, CH4, CmHn, etc. It is drawn from the bottom, and is sent out for use after the purification system removes impurities such as tar. The ash is discharged from the lower part of the gasifier. The generator set control module adopts the microprocessor-based generator set control technology, which has many functions such as automatic data recording, automatic operation, automatic control, automatic protection, etc., and has good reliability and stable performance. The operating parameters of the unit are displayed by a large-screen LCD, which displays large and accurate data.


which is convenient for transportation and installation

Biomass gasifier is composed of furnace body system, dust removal system, cooling system, tar purification system, tar separation system, Roots blower, electrical control system, etc. The syngas generator set is mainly composed of a gas engine, a three-phase AC synchronous engine, a control cabinet, a common chassis and a gas source link part. The KX series biomass synthesis gas power generation system adopts modular design, which is convenient for transportation and installation. The KX series biomass gasifier is a downdraft, fluidized bed biomass gasifier independently designed and developed for the needs of biomass synthesis gas power generation. This series of biomass gasifier uses PLC intelligent system control The system fully realizes long-term fully automatic work. And the dry purification technology used in the gasifier avoids secondary water pollution to the natural environment. Moreover, the raw materials are highly adaptable, requiring the size of the biomass raw materials to be ≤30mm and the moisture content ≤20%. Pass various biomass raw materials through the gasifier for drying, cracking, oxidation and reduction to produce biomass synthesis gas, and then the biomass synthesis gas is cooled, dusted, and cooled to remove tar and impurities in the gas, and the processed high-quality , The pure biomass synthesis gas is transported to the synthesis gas generator set for power generation. In this way, while realizing the conversion of low-value biomass energy from solid to gaseous, it greatly improves the utilization efficiency of solid biomass energy. Biomass gasification is the process of converting solid biomass (wood chips, branches, organic household waste, agricultural and forestry waste, etc.) into combustible biomass synthesis gas. By controlling the reaction process, carbon, hydrogen, and oxygen are chemically reacted. It is synthesized into combustible components such as carbon monoxide, hydrogen and methane, and most of the energy in biomass raw materials is transferred to biomass synthesis gas. This is the gasification process of biomass gasifier.
