Biomass power generation---selling electricity through partition walls, solving the predicament of biomass power generation industry


Entering 2022, the introduction of a series of policies by the energy authorities has further clarified the policy direction of promoting the nearby transaction of distributed power generation, which is of great significance for non-water renewable energy.
Wind power, photovoltaics and biomass power generation are the troika of non-water renewable energy sources. However, unlike wind power and photovoltaics, biomass power generation has the characteristics of distributed energy in essence.
Wind power and photovoltaics have entered the era of large investment and large bases, and a large power grid is needed to support power transmission and distribution. Biomass power generation is subject to fuel restrictions, and the installed capacity of 50,000 units is considered a super project.
Although the installed scale of power generation after biotechnology is not large, the quality of power generation is very high. The safety, stability and sustainability of its power supply are far from comparable to wind power and photovoltaics, and are completely comparable to coal-fired power generation.
Under the environment of dual control of energy consumption and reduction of coal power production capacity, the demand for high-quality green power by production enterprises is increasing, and biomass power generation can completely replace coal power to meet production needs to a certain extent.
The biggest problem that currently plagues biomass power generation is that fuel costs remain high, subsidies are not in place, and it is impossible to achieve stable profitability by relying on the existing power generation system.
In line with the requirements of the market-oriented reform of coal-fired electricity prices, there is no upper limit on the electricity price of high-energy-consuming enterprises. Assuming that electricity sales through partition walls are fully liberalized, biomass power generation can be obtained without relying on subsidies at all.
Most of my country's biomass cogeneration projects are located in industrial parks, and production enterprises basically have huge demand for electricity and heat loads. With the release of electricity sales through partition walls, the economy of biomass power generation will be greatly improved.
The biomass power generation project sells electricity to enterprises in the park, and the buying and selling price is not lower than the subsidized electricity price of 0.75, or even higher, and the electricity price settlement is very timely, and there is no subsidy in place.
At present, my country's biomass power generation is transforming to cogeneration, supplementing the lack of cash flow through heat and steam supply. But this is far from enough. Only by opening up the partition wall to sell electricity as soon as possible can we truly break through the industrial predicament.
Some experts predict that the sale of electricity through distributed energy partitions will be released in the past two years. By then, biomass power generation will surely become the core of power supply and heating in an industrial park, let us look forward to it together.

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.
