biomass gasification advantages and disadvantages

1.What is biomass ?
A variety of species are formed by photosynthesis using the atmosphere, water, land, etc.; thus, biomass is a general term for all living organic stuff that can grow. Plants, animals, and bacteria all make up biomass.

The term “biomass” broadly refers to all plants, microbes, and animals that consume them, as well as the waste products they create, such as crops, agricultural residues, wood, and animal dung.

Narrow definition: The term “biomass” refers primarily to the agricultural and forestry production processes, which also include the production of food, fruit straw, trees, and other lignocellulose (also known as lignin), offal, agricultural and forestry waste, and materials used in the production of livestock, such as manure and waste.

2. What is biomass gasification?
The process of pyrolyzing, oxidizing, and reductively reforming biomass polymers with the aid of air part (or oxygen), water vapor, and finally into combustible gases such as carbon monoxide, hydrogen, and low molecular hydrocarbons is known as biomass gasification.

advantages：
1.High level of automation：
For up to 20 hours, the biomass gasification system can run unattended. The system has excellent stability, one-button start and stop, high safety, and integrated and interlocked components. To make supervision easier, the 5G remote smart energy management system can remotely manage the energy system. The biomass gasification system typically runs with just one person on duty, with a light workload that is acceptable for long-term use. High safety, emergency shutdown that shuts down automatically, waiting for engineers to save you.

2. Long service life:
With a 20-year design life, the biomass gasification system has more than 30% stainless steel components. The motors utilized in the Haiqi biomass gasification system are all top-tier Chinese manufacturers, while the electrical appliances are all well-known European brands. The entire Haiqi biomass gasification system is constructed of modular steel structures, which lowers the cost of civil engineering and increases service life. The generator sets are all top-of-the-line household models that can generate electricity for 8000 hours per year.

3.The energy utilization rate of the system is high, and by-products turn waste into treasure: Heat energy from cooling water is used by Haiqi manufacturers’ biomass gasification system to dry raw materials. Hot water or water vapor is created using the generator set’s heat energy. There is no wasted energy in the entire biomass gasification system because it is recycled to raise the system’s overall effectiveness. To boost the added value of products, secondary purification techniques including biochar, wood tar, and wood vinegar can be applied.

4.The system design is more compact: 
Equipment installation is simplified by the modular architecture of the biomass gasification system produced by Haiqi. The site use space is improved by the higher system space utilization rate. The area is orderly and spotless, and there are no scents or contaminants on the ground. Reduce the expenditure in the biomass gasification system and the energy consumption of unnecessary supporting equipment.

disadvantages：

The investment scale is larger than that of domestic counterparts

Other biomass gasification system suppliers in China:

Low cost and minimal investment are the benefits.

1. Inadequate configuration: insufficient automation, need for extra labor, and inability to implement real-time monitoring of the biomass gasification system

2. Short service life: use regular carbon steel, avoid prolonged use, and avoid taking any precautions against high temperatures, corrosive gas, corrosive liquid, and oxidizing gas.

3. Inadequate after-sales support: The cost of the biomass gasification system is inexpensive, and the after-sales support is nonexistent.
4. Outdated system design: Continuing the old system design, it requires a lot of civil engineering, takes up a lot of space, has a lot of auxiliary equipment, and uses a lot of energy.

5. Poor economic returns: The biomass gasification system requires more time to maintain than it does to operate, and the economy is weak. It cannot operate steadily and constantly if there are extended periods of downtime, and the economy suffers.

Biomass gasification related case introduction
Docking a biomass gasifier with a steam boiler: The client has a 6-ton steam boiler in a food business. It responds to the call for environmental preservation and combines the circumstances of various local agricultural and forestry biofuels to completely examine domestic biogas production because there is no centralized gas supply pipeline network in the area. The Haiqi biomass gasifier was chosen for the equipment scenario in order to co-generate gas and charcoal, and the biomass gas was used to power the boiler. The equipment expenditure can be recovered in a month, but the daily cost of energy-saving fuel exceeds 30,000 yuan.

Project to generate 100 KW of electricity from gasification of wood chips in Congo: Wood chip crushers, pyrolysis gasifiers, gas purification systems, systems for generating electricity using internal combustion engines, control systems, water cooling systems, etc. are all provided by Haiqi. 100-150 kg/h of wood chips are added to the furnace each hour, and 100 kw/h of electricity is produced. The Haiqi gasification power station is utilized to supply electricity to the customer’s factory area, thereby resolving the issue of the lack of power supply in this location.

Russia 200KW Biomass Gasification Power Station: The governments of Russia and the Netherlands have invested in this project, which also includes investments in wood pellet manufacturing facilities. A portion of the pellets produced are used in the biomass gasification power plant in Haiqi, and the electricity produced powers the factory’s machinery.

Butt mesh bag dryer and charcoal gas cogeneration project using rice husks: In order to create synthesis gas, which serves as the dryer’s heat source, the customer utilizes rice husk to gasify in the Haiqi gasifier. The gasified rice husk charcoal is then used by the customer. supplied to manufacturers of activated carbon.

This project is located in a university that is developing a new energy school, and as a result, its heating boiler uses biomass energy. The biomass gasification furnace from Haiqi was ultimately chosen for heating after numerous examinations and comparisons. There is a 10-ton hot water boiler used, and the area is around 140,000 square meters. Customers can purchase a set of HQ3000 fixed-bed gasifiers from our company, which can simultaneously earn them more than 300 yuan and save them more than 1 million dollars in heating expenditures each year. A ton of biochar costs between 1000 and 1200 yuan to sell.

Cow dung pyrolysis gasification case: Traditionally, animal manure is treated primarily by anaerobic fermentation, which yields biogas. However, the biogas leftover and biogas slurry generated by this method cannot be properly disposed of and will result in secondary pollution. Utilization In addition to producing gas from cow dung, our biomass gasifier can also produce biochar. This plant can produce 3 tons of biomass and 15,000 m3 of gas per day from processing 50 tons of cow dung with an 80% moisture content each day. The entire pyrolysis gasification system, including the material charcoal, has no secondary pollution.

Canadian biomass gasifier docking drum dryer project: Haiqi supplied both the gasifier and the dryer, and the customer is operating the pellet production line. The customer used wood chips as the gasifier’s raw material, and the gasifier produced combustible gas as a heat source for the dryer. Dry the wood chips. The dryer is 1.8m*18m in size and has a calorific value of 1.2 million kcal. The gasifier’s model number is HQ-LX2000. Customers save 3.5 million yuan annually compared to fuel and gas consumption.
