Summary

Summary: 
A Polish SME, being a private engineering company, has developed burners for co-firing grinded biomass dust with a coal dust or a brown coal dust in a power boiler. The burner can be mounted as a new unit or in existing coal dust swirl burners being modernized. The partners for commercial agreement with technical assistance are sought.

Description

Description: 

A Polish SME, being a private engineering company has developed burners for co-firing grinded biomass dust with a coal dust or a brown coal dust in a power boiler. The low-emission swirl burners are provided for existing or new pulverized coal-fired boiler (PC boilers) with coal swirl burners where biomass firing is expected. The burner can be mounted as a new unit or in existing coal dust swirl burners being modernized.
The technology allows reducing environmental nuisance of power generation being low emission technology of fuel firing. It facilitates reducing CO2 from exhaust fumes of PC boilers by their modernization and replacing either part or whole amount of coal with biomass.
The biomass dust burners are mounted on boiler’s combustion chamber walls in the coal-fired burners and start-up burners zone.
Energy acquired from biomass combustion replaces energy derived from coal burning, improving the C02 emission balance to the environment.
The burner provides generation of renewable energy at lower investment costs and limited modifications of power generating plants especially with partial using of existing coal dust swirl burners. The low-emission swirl burner for co-firing biomass with coal dust is fed with biomass dust and coal dust and combustion air. Both: biomass dust and coal dust are delivered to the burner by pneumatic transport.
Thermal capacity adjustment of the burner is accomplished outside the burner by fuel (coal and biomass) and combustion air flow adjustment supplied to the burner.
The burner is designed for steam or water boilers with capacity over 40 MWt.
Burners used in the technology are company’s original solution and are protected by patent.
Basic requirement for applying offered burners is proper preparation of biomass by its pulverization and drying. Therefore complex company’s offer includes delivery and burners’ mounting including preparation system (drying, grinding), storage and biomass dust transportation to the burners.
The company is interested in introducing its burners to heating plants and combined heat and power plants or industrial plant on the basis of a commercial agreement with technical assistance.

Advantages & innovations

Cooperation plus value: 
Innovation aspects & Main advantages Innovative construction of developed burners allows for: - generation of renewable energy in steam boilers and water boilers at lower investment costs - reducing the environmental impact of excessive CO2 emission - safe firing of biomass in large power boilers - possibility of applying burners firing biomass dust in existing power boilers by its modernization - safe co-firing biomass dust with other fuels in one unit

Stage of development

Cooperation stage dev stage: 
Available for demonstration

Partner sought

Cooperation area: 
The company seeks industry partner for application of the technology in Combined Heat and Power (CHP) plant, Heat Plant (HP) plant or industrial plant. They are open for further product development but are looking for a company able to implement it and adjust for the local conditions.
