Resumen:
Un instituto de investigación polaco especializado en tecnologías avanzadas de producción de energía, y especialmente tecnologías de combustión, ha desarrollado una tobera de aire para plantas en las que se utilizan calderas de lecho fluidizado de alta potencia alimentadas con carbón. La función de las toberas es dispersar el aire uniformemente en la sección transversal del fondo de la cámara del horno, lo que aumenta la eficacia en la combustión y reduce los niveles de emisión de óxidos de nitrógeno y carbono. Se buscan socios industriales con el fin de establecer acuerdos de cooperación o comercialización con asistencia técnica: adaptación a necesidades específicas, ingeniería y consultoría técnica.

Details

Tittle:
Innovative air nozzle for use in power plants.
Summary:
A Polish research institute from the field of advanced power technologies developed an air nozzle for use in power units with high-power coal-fired fluidised bed boilers used in power plants (for hard coal and lignite). The Polish institute seeks industrial partners for a technical co-operation or a commercial agreement with technical assistance such as: adaptation to specific needs, engineering and technical consultancy.
Description:
Polish Research institute offering the expertise and know-how in advanced energy technologies and clean industrial technologies and, in particular, the combustion technology, developed an air nozzle for use in power plants.
The primary air nozzle developed by the Institute is an inseparable part of the air distributor of a fluidised bed circulation power boiler for solid fuels. The role of the air nozzles is to provide unified air dispersion in the cross-section of the bottom part of the furnace chamber resulting in high combustion effectiveness and low levels of nitrogen oxides and carbon oxides emissions.
The device ensures maximum abrasibility of the bed material and long-term operation without sinters and blocking the air holes.
The basic challenge when designing air nozzles is to be able to form a shape that provides optimal protection against back flow of the bed material into the compressed air boxes with a simultaneous low drop in pressure. The new nozzle geometry efficiently integrates two opposing requirements for these devices: low drop in pressure, which made it possible to reduce the internal load of an electrical power unit, and high resistance to the back flow of the bed material, which enables the unit to work without the need of having costly operational downtime.

The proposed solution is intended for power plants using fluidised bed boilers in the heat and electricity production process.

The Polish institute seeks industrial partners for a Technical co-operation or a Commercial agreement with Technical assistance such as: adaptation to specific needs, engineering and technical consultancy.
Advantages and Innovations:
The most innovative feature of the nozzle, is the optimal shape.The innovative nature of this solution consists in combining the advantages of nozzles with high and low pressure drops, i.e. providing an effective barrier against the back flow of loose materials into the compressed air boxes of fluidised bed boilers, while retaining a relative low drop in the nozzle pressure.
This provides following advantages:
- significantly reduce the back flow of inert material, which causes expensive power unit downtime,
- reduce power plant's internal load thanks to an insignificant drop in pressure, and
- evenly distribute oxygen in the cross-section of the boiler furnace chamber.
