Spray Nozzles for APC in Power Plants is the Hot Topic Hour on Thursday,
January 14, 2010
Spray nozzles are utilized in a wide range of applications in power plants to
help minimize emissions of pollutants. Among the applications are: control of
SO2 by FGDs, NOx control with aqueous ammonia and SNCR in-furnace, SO3 control
additives, mercury control with activated carbon or other chemical additives and
even growing applications for the combustion of mixtures of fossil and biomass
fuels.
With the need to continue reducing emissions, spray nozzle design and location
has been under increased scrutiny as a lower cost way to improve the performance
of existing and new APC equipment. Nozzles are available in a wide variety of
materials, flow rates and capabilities to handle every material from water to
powdered solids. Proper selection and location of the spray nozzles can improve
the efficiency of the removal of the specific pollutant. Abrasion and corrosion
resistance, plugging or clogging, self cleaning, efficiency and maintenance
requirements are also considerations in the selection of a spray nozzle and the
material distribution manifolds. Parameters used for the design and selection of
the nozzle and location of nozzles in a duct, vessel or combustion zone can
include: total flow rate, number of spray levels, number of nozzles, spray
direction, spray angle, reaction constants, droplet size and its spectrum. At
the last Hot Topic Hour on this subject in November 2007, several experts
discussed the improvements that have been made to nozzles and the way that they
are located and used up to that point.
The following speakers will build on that by describing the advances that have
been made in the last two years, presenting their experience with some of the
technologies described then and discussing new technology or nozzles under
development.
Presenters are:
Mike Bruno, Applications Engineering Manager at BETE Fog Nozzle, Inc. a leading
designer and manufacturer of spray nozzles for pollution control systems and
general industry. Mike will present two case studies highlighting recent
examples where BETE has used their integrated engineering design, development,
testing and manufacturing resources to meet our customer's specialized need for
pollution-control process improvements. Each example will demonstrate a unique
method of using our current technologies, coupled with our extensive experience,
to deliver successful solutions for today's pollution control problems.
Mughis Naqvi P.Eng., Sales & Marketing Manager, Environmental Division, Lechler,
Inc. a leading worldwide supplier of injection spray nozzle systems for gas
cooling/humidification systems as well as Air Pollution Control for NOx and SOx
removal. His presentation will discuss various areas in air pollution control
where spray nozzles play a key role. He will discuss the types of spray nozzles
used in SDA's and CFB scrubbers as well as SCR and SNCRs. A quick overview of
spray nozzle designs and fundamentals will also be presented.
