Gasification of biomass

The BPS PROJECT CZ offers gasifiers with smallest performance starting on 25 kWe up to 2,200 kWe power applications. Technology has a great advantage in cost savings by replacing expensive conventional fuels with cheap and locally available biomass. So you can successfully replace diesel, LPG, natural gas and other non-renewable resources.

By working with one of the technology leaders, who works in the gasification of more than 25 years, we can provide more than 900 functional references worldwide, including Europe and the USA. All production and research are certified according to ISO 9001, ISO 14001 and 18001 OHAS. Gasification unit and all its parts have CE certificates, which are ready for installation and operation in the European Union and adapted to local conditions.

The BPS PROJECT CZ due to membership in VAE CONTROLS GROUP provides extra guarantee of fast installation, commissioning and providing service works. Our team of over 400 engineers are ready to implement your project and ensure its long-term operation. 

Gasification of biomass 

Biomass gasification can be described as the process of converting solid carbon-based fuels (wood chips, agricultural residues, etc..) in flammable gas mixtures, often called called "syngas." Gasification is carried out for a limited supply of air at temperatures between 700 and 1200˚ Celsius. The basic advantage is the high conversion efficiency and lower quality fuel gas that can be effectively used to produce electricity and heat. The entire process is completely ecological and environmentally friendly, modern technology can solve all potential pollution associated with the use of biomass.

In the context of electricity and heat production technologies using local renewable resources, helping to reduce global warming and in terms of the economy, due to its state-guaranteed feed-in tariffs interesting investment.

 In gasification units can be easily used all wood-based materials, as well as the waste generated from agricultural production (corn cobs, dung, pressed grass, poultry dung). 

 

Basic technological process

- Preparation = drying, crushing, raw material dosage

- Gasification = chemical fuel conversion process

- Cooling and gas cleaning = getting rid of undesirable substances and residues solids

- Burning gas in a cogeneration unit = production of electricity and heat

Key parameters are humidity and size of each part of the biomass. The basic assumption is the raw material moisture up to 20% and the maximum size of individual parts 15 to 75 mm.

Pre-drying materials designed to gasify and its transport to the gasification reactor is ensured through rotary dryers and associated conveyors, including a small lift delivering prepared ingredients directly into the gasifier. Biomass is automatically dosed into the reactor at desired intervals.

Gasifier itself is a chemical reactor, which hosts various complex physical and chemical processes that are essential to the drying, pyrolysis, combustion and reduction.

The gasification reactor is designed in such way that the air is dosed in a controlled manner, resulting in partial oxidation of biomass to gas, this way the process differs significantly from the actual combustion. One kg of biomass is converted to 2.5-3.0 Nm3 gas with a calorific value between 1000-1300 Kcal Nm3.

The gas coming from the reactor has a temperature of around 450˚ degrees Celsius and higher. For subsequent processes is crucial that the hot gas is almost free from tar, residual substances are safely absorbed and cleaned in a patented, multiple-degree filter system.

The level of gas purity then reaches completely safe values ​​needed for the smooth operation of cogeneration units and eliminating damage and accumulation of dirt. Cogeneration units offer manufacturers like JENBACHER, SCHMITT-ENERTEC, Cummins, GUASCOR and other renowned companies.
