Biomass power generation, the most stable renewable energy source for heat and electricity


There is a view in the power industry that no electricity can have both: the triangle of cheapness, greenness and stability. This impossible triangle theory continues to this day and still has a big market.
For example, coal-fired power generation is cheap, stable and reliable, but the intensity of carbon dioxide emissions is very high; although hydropower, wind power and photovoltaics are environmentally friendly, their power generation is unstable due to seasonal and natural factors.
However, agricultural and forestry biomass power generation is different from the above-mentioned types of electricity, and can completely subvert the impossible triangular theory of cheapness, environmental protection and stability. Compared with wind power and photovoltaics, it is more efficient and stable renewable energy.
Power generation efficiency far exceeds that of wind power and photovoltaics:
In 2020, the grid-connected wind power generation will be 466.5 billion kWh, and the grid-connected solar power will be 260.5 billion kWh. At that time, the total installed capacity of wind power was 281 million kilowatts, and the total installed capacity of photovoltaic power generation was 253 million kilowatts.
The installed capacity of biomass power generation is 13.3 million kilowatts, and the power generation capacity is 57 billion kilowatt hours. The installed capacity of wind power is 21 times that of biomass power generation, and the installed capacity of photovoltaic power generation is 19 times. The power generation is 8 times and 4.5 times respectively.
It should be pointed out that biomass power generation follows the route of determining electricity by heat, and more than 40% of the energy is used for heating. If the biomass power plant generates all the electricity, the power generation efficiency is higher.
According to relevant data, for wind power, photovoltaic and biomass power generation with the same installed capacity, if only power generation is considered without heat supply, biomass power generation will be about 5 times that of wind power and about 8 times that of photovoltaics.
The only renewable heat source in the world
my country is promoting clean energy power to replace coal power, and renewable energy power generation can replace part of coal power power, but when it comes to residential central heating and industrial production heat load, wind power and photovoltaics are powerless.
Biomass energy is the only renewable heat source in the world. In the future, biomass power generation will be the mainstream of heat-based electricity generation and cogeneration. Biomass thermal power will fill the heat gap after coal power has been de-capacity.
Especially in small and medium-sized towns and industrial parks, biomass clean heating and biomass cogeneration projects have become the core main force of energy supply, and become the energy guarantee for residential heating and industrial production.
my country has enough biomass fuel to support the construction of thousands of biomass power plants, and biomass power generation is also the only industry that can process agricultural and forestry wastes on a large scale, and it is the most stable renewable energy source for heating and power supply.

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.

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.
