Summary

A Polish SME, being a private engineering company  has developed burners for biomass dust firing. The technology enables low emissions for fuel firing, leading to a reduction in environmental impact associated with power generation. 
Biomass dust burners are mounted on boiler’s combustion chamber walls in the coalfired burners and startup burners zone.
The partners for commercial agreement with technical assistance are sought.

Description

A Polish SME, being a private engineering company has developed burners for biomass dust firing. 

The technology enables low emissions for fuel firing, leading to a reduction in environmental impact associated with power generation.It facilitates the reduction of CO2 from exhaust fumes of PC boilers (Pulverized Coal boilers) by their modernization and replacing either part or whole amount of coal with biomass.

The burners developed enable firing biomass directly in boilers or co-firing biomass with different fuel supplied to the boiler with different burners. Burners are fed with biomass dust and cold or hot combustion air.

Biomass dust burners are mounted on boiler’s combustion chamber walls in the coal-fired burners and start-up burners zone.

Thermal capacity adjustment of the burner is accomplished outside the burner by fuel and combustion air flow adjustment supplied to the burner.

The company offers burners for firing pulverized biomass mixture with low dust concentration, from 0,3 to 0,8 kg of dust in kg of transport air and with high dust concentration over 4 kg in kg of transport air supplied to the burner by pneumatic system.

The burners are designed for steam or water boilers with a capacity of over 5 MWt.

They offer biomass swirl burners with wide range of capacity from about 1000 kWt to 20 Mwt.

The burners used in the technology are the company’s original solution and are protected by a patent.

A basic requirement for applying the 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 and Innovations

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

- advantage conditions of fuel ignition

Stage Of Development

Available for demonstration

Requested partner

The company seeks industry partner for aplication 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.
