Artykuł Flue gas treatment system in Bydgoszcz pochodzi z serwisu Qenergy Sp. z.o.o..

Feather gasification installation at the facility of Indykpol S.A. is the only operating installation of this type in the world. It is a pioneering system, which proved its effectiveness over years of work, successfully replacing the coal-fired boiler room, thus contributing to the reduction of gas emissions to the atmosphere. Feathers are a serious problem for many poultry slaughterhouses, as its utilization is relatively expensive and requires engagement of third parties (transport, utilization). The installation allows for reduction of costs associated with the current utilization of nuisance waste. What distinguishes this installation is the possibility of managing waste at the place of its origin and production of fully renewable thermal energy. The installation in Olsztyn uses the latest technical and technological solutions available on the market.

Utilization of Indykpol S.A. waste

The main objective of the project was the construction of a gasification system for slaughter waste, namely feathers, formed in the process of slaughter and processing of poultry. Until the new system was started, said waste was collected for a fee by specialized external companies. Solving the problem of waste internally within the company allowed avoiding an increase in prices for disposal. Now post-slaughter waste is the input fuel for the installation, and the main product is steam heat, covering 70% of the plant needs (the remaining 30% of the demand is covered by a newly installed gas boiler). In addition, the feather gasification installation replaced the coal-fired boiler room (old coal boilers were out of service), what significantly contributed to the reduction of harmful gas emissions to the atmosphere. The installation we built is fully automated. This makes it easy to control the process and quickly affect the quality of the gas produced. The installation in Olsztyn utilizes 10,000 tons of feathers a year, generating 3.5 MW thermal energy.

As members of the consortium, we provided all the required components and performed all the assembly work necessary to assemble and run “4.8 MW alternative fuel heating plant in Skarżysko-Kamienna” according to the construction and execution project received. The heating plant was connected to the existing heating network of the city of Skarżysko-Kamienna, replacing 4.9 MW of thermal energy (the carrier of which is hot domestic water) previously produced from hard coal by energy generated from the so-called alternative fuel, i.e. waste of the code 19 12 10. The new heat plant was built on the premises of the existing heating plant of Skarżysko-Kamienna at 11 listopada St.. The design of the heating plant takes advantage of gasification technology. Hot exhaust gases obtained after burning the gas generated during gasification of the fuel are the heat carrier that is collected by the waste water boiler.

Our tasks included:

• Construction of a reception hall, unloading and transporting fuel to the gasification chamber.
• Delivery and assembly and commissioning of the gasification chamber with the fuel dispensing system, service platforms, fans, fittings and auxiliary equipment.Dostarczenie oraz montaż i uruchomienie komory spalania wraz z palnikiem stabilizującym na gaz ziemny, układem wirowego wlotu gazu oraz powietrza, odpowiednimi wentylatorami, podestami obsługowymi, armaturą i urządzeniami pomocniczymi.

We have analysed the cost-effectiveness of building a biomass installation for the production of combined electricity and heat as well as a construction project for this investment. An important element of the study was the analysis of the renewable energy market, because its price is the basic revenue element of the undertaking. In the study, we presented a solution for high-efficiency cogeneration with an electric power of 800 kW and thermal power of 4000 kW at the Zakład Drzwny Napiwoda plant. The fuel in the installation is biomass-derived mainly from wood processed in the sawmill and from forest management. Electricity is used for the own sawmill’s needs, and the surplus is sold to the network. Thermal energy is used in its entirety for the technological processes of the plant, while in the heating season its part is sold to local municipal customers.

Energy from alternative fuel

Gasifying systems for alternative fuel

Waste code 19 12 10

Many years of research on the conversion of organic waste into energy allowed the construction of the reactor QM12 for gasification of solid fuel. Tests on the systems confirmed that the whole process, including the combustible gas formed, causes very low emissions. Resulting in a small amount of gas to meet all the requirements thermal treatment plants by the European Union. It is possible to expand the gasification system, so that the end product of the system was not a gas, but electricity and heat. The whole process of gasification is controlled, operated and registered by an automation system.

QM12 reactor may be adapted to different types of waste treatment, such as:

• municipal
• medical
• pharmaceutical
• tanning
• industrial (railway sleepers, tires)
• food
• animal (bone meal)

What happens in the gasifying chamber…

Gasification is a process that converts carbonaceous materials, such as biomass, wood, various types of waste including municipal and industrial waste, coal, petroleum, petroleum coke, into a calorific gas consisting mainly of carbon monoxide, hydrogen and methane under high temperatures. There are three main stages that might be designated in the gasifier:

• Drying: The emitted water vapor reacts during gasification of coal, converting it into carbon monoxide and hydrogen.
• Pyrolysis: at temperatures of 250-750 ° C there proceeds  the process of thermal cracking (pyrolysis) to the gas containing CO, H2, CH4 and CO2, water vapor and fumes aromatics(benzene, toluene, xylenes, etc.) to tar, oil, charcoal and minerals.
• Gasification: In this phase, which requires temperatures above 750 ° C, runs a number of endothermic reactions with oxygen deficit and partly with water vapor, CO2 and even with that liquid and solid materials pyrolysis transformed mainly into carbon monoxide and hydrogen, and partly even methane.

The efficiency of the process determined by the ratio of chemical energy produced synthesis gas for chemical energy raw material. In practice, this efficiency reaches up to 98%, depending on the technology used, raw material moisture and plant size.

After gasification, the gas is burned in the combustion chamber and is directed to a waste heat boiler where there is hot water or steam. The chilled gas is directed to a filter system where it is treated until its parameters reach the level stated in the regulations. The quality of exhaust emissions will be subject to continuous measurement.

The temperature of the gasification process lies in the range of 400-850 ° C. The temperature in the combustion chamber reaches a level above 900 ° C and must guarantee that the residing time of flue gas at temperatures above 850 ° C for 2 seconds.

Gasification is a process that converts carbonaceous materials, such as biomass, wood, various types of waste including municipal and industrial waste, coal, petroleum, petroleum coke, into a calorific gas consisting mainly of carbon monoxide, hydrogen and methane under high temperatures.

The process is based on a chain of reactions between the carbon in the fuel and the supplied oxidizer: oxygen (from the air), steam, hydrogen or carbon dioxide. The gasification process takes place in the temperatures between 400 and 850 °C. The final product of the process is combustible gas. The gas is called producer gas or syngas (or wood gas when fuelled by wood) and may be more efficiently converted into energy (both thermal and electric) than would be possible by direct combustion of the fuel. Also, corrosive ash elements such as chloride and potassium may by refined out by the gasification process, allowing high temperature combustion of the gas from otherwise problematic fuels.

Our gasification systems separate the gasifying process from combustion of the produced gas by using a separate gasifying and combustion chamber. Therefore, the whole process is divided into two major elements:

1. Devolatilization of the organic substances under high temperature, often above 1000 °C and then transformation of remaining organic carbon at app. 800 °C into a mixture of carbon monoxide, carbon dioxide and hydrogen. This takes place in the presence of air and steam.
2. Combustion of this gas in a separate combustion chamber under fully controlled conditions with the possibility of multilevel gas and flue gas treatment.

Separating the gasification and combustion process allows for much better control of the whole process, which in turn enables technological changes to improve and fine-tune the whole system.
