A
feed
water heater is an equipment utilized to preheat boiler feed
water in a power plant. Preheating has many advantages such as
improved thermodynamic efficiency of the system. The function of feed
water heaters is to capture internal energy spent from steam and
utilize that energy to preheat condensate feed water. It reduces
plant operating costs. It also aids to avoid thermal shock to the
boiler metal when the feedwater is introduced back into the steam
cycle.
The
overall market for feedwater heater is segmented on the basis of
technology, application and geography. There are two main types of
feed water heaters such as low pressure heater and high pressure
heater. Low pressure feedwater heater and high pressure feedwater
heater are used as per the cycle optimization requirements. High
pressure feedwater heatersare placedbetween the boiler feedwater pump
and the boiler. Low pressure feedwater heaters between the main
condensing pumps and the boiler feedwater pumps. It consist of a
U-Tube bundle heat exchanger mounted in a tube sheet and surrounded
by a steam shell. Feed water heaters are used in various power plants
such as gas powered power plant, boiler steam powered power plant and
nuclear powered power plant. North America and Europe constitute
major chunk of global market for feed water heater. Countries such as
the U.S, Canada, Russia, Germany, France, U.K and Italy have
substantial market share of feed water heaters. Asia Pacific, Latin
America and Middle East have ample share of global feed water heater
market. China and India are the fastest growing markets for feed
water heaters across the globe.
One
of the primary drivers of growth for feed water heater market is the
rising global demand for power and energy. World population is
increasing day by day and power demand is increasing simultaneously.
Increased construction and industrial activities across the globe
have further boosted the demand for power. Feed water heaters demand
is increasing with increase in power generation activities. The
number of nuclear power plants has increased since last decade.
Countries such as India and China have boosted the number of nuclear
power plants. Increasing number of nuclear power plants is also
boosting the demand for feedwater heaters. The demand for feed water
heaters in existing and upcoming nuclear power stations is bound to
increase.However, negative public opinion regarding the development
of nuclear power plants may hamper the growth of feed water heaters
market. There is a stark shift towards renewable energy sources for
power generation such nuclear power plants. All these factors predict
a good growth trajectory for feed water heater market over the
forecast period.
Some
of the major players in the market include BWX Technologies Inc.,
Westinghouse Electric Company LLC, KNM Group Berhad,Thermal
Engineering International (USA) Inc., SPX Heat Transfer Inc., Foster
Wheeler AG, Balcke-Dur GmbH and Alstom Power SA among others.
