Biomass Pyrolysis Plant

Types of biomass pyrolysis waste

Biomass pyrolysis, usually refers to biomass is heated to cause molecular decomposition to produce coke, condensable liquid, and gas products in an oxygen-free or low-oxygen environment.

Item	Description
Agricultural wastes	Crop straw, rice husk, bagasse
Forestry waste ‌	Branches, leaves, sawdust
Urban organic waste	Kitchen waste, yard waste, feces
Industrial organic waste	Food processing waste, wood processing waste

Biomass pyrolysis process

Dry: The moisture content of biomass raw materials is usually between 20%-40%. Through the roller dryer, the moisture content reduces to 8%-10%.

Pretreatment: Raw materials such as wood chips and rice husks have small particle sizes and can be used directly after screening. The raw materials of the straw need to be crushed by the hammer crusher.

Pyrolysis: Biomass pyrolysis technology can be divided into three types according to different pyrolysis conditions. Slow pyrolysis, conventional pyrolysis, and fast pyrolysis. Slow pyrolysis is mainly used for charcoal, and the biomass can be pyrolyzed for a long time at a very low heating rate and temperature below 400℃, and the maximum coke yield can be 35%.Conventional pyrolysis is putting the biomass raw material into the conventional pyrolysis device, and pyrolysis at 380℃~450℃ and a low heating rate. It can produce 20%~25% biochar by weight of raw material and 10%~20% oil by weight. Rapid pyrolysis is putting finely ground biomass raw materials into a rapid pyrolysis device, and the biomass is pyrolyzed under atmospheric pressure and ultra-high heating rate, and the bio-oil can generally reach 40% to 60% of the weight of the raw material.

Carbon ash separation: The carbon ash produced during pyrolysis needs to be separated from the oil for subsequent treatment and utilization.

Cooling collection of oil: The oil produced by rapid pyrolysis has the characteristics of high density, acidity, high moisture content, and low calorific value. It needs to be cooled and collected to be stored and transported. Biomass pyrolysis equipment.

biomass pyrolysis equipment

Hammer crushers

Hammer crushers impact and squeeze the material with high-speed rotating hammer heads, which could turn bulk material into small particles and improve treatment efficiency. It is suitable for the treatment of various biomass raw materials, including wood, agricultural waste, domestic waste, etc. The hammer crusher has a simple structure. Maintenance and operation are easier, it is suitable for large-scale production.

Biomass pyrolysis reator

The reactor is a kind of equipment for the pyrolysis of biomass raw materials such as wood, straw, and agricultural waste at high temperatures, mainly producing gas, liquid, and solid products.Fluidized bed furnace: Pyrolysis by fluidized bed technology, suitable for large-scale production. Fixed bed furnace: Pyrolysis is performed in a fixed bed, which is suitable for laboratory and small-scale production. Other types: such as rotating cone reactors, moving bed reactors, etc., it is suitable for the specific needs of the production. ‌

Cyclone separator

It is used for gas-solid separation. And adapt to biomass pyrolysis systems. In particular, it plays a key role in the development and utilization of biomass energy. The main function of a biomass pyrolysis cyclone separator is to separate charcoal powder from biomass pyrolysis gas to improve the quality of oil.

Condenser

It is a core part of the cooling system to quickly condense the condensable volatiles into liquid.it is usually adapted to Water-cooled or air-cooled to quickly cool the vapor below room temperature by circulating water or cold air so that volatile condensation into liquid ‌.

Drying roller

The heating system heats the air to a certain temperature to make biomass material quickly evaporate. The air circulation system sends the heated air into the drying room, makes full contact with the biomass material, and takes the water away‌. The air after drying filtered by a dust system to remove dust and other impurities from it. Then let out to the outdoors, thereby drying the biomass feedstock.

Reliable Biomass Pyrolysis Machine of AGICO Group

the biomass pyrolysis technology could react in an anaerobic or low-oxygen environment. Biomass is decomposed by high-temperature heating to produce gas, liquid, and solid. This product could be used to generate power, heat, and produce pyrolysis oil and fuel. It has high energy conversion efficiency.

During pyrolysis, the biomass equipment does not produce harmful gas and is environmentally friendly. In addition, Biomass resources are rich and renewable, which is conducive to the sustainable development of energy ‌.

The biomass pyrolysis technology could reduce energy costs and improve economic efficiency. Through the continuous pyrolysis production process, the biomass with low energy density that is difficult to process by conventional methods can be converted into gas, liquid, and solid products with high energy density. It reduces the volume of biomass and is convenient for storage and transportation
