Slide 22


Slide 23

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 Supercritical Boilers

Supercritical pressure boiler has no drum and heat absorbing surface being, in effect, one continuous tube, in which

the water & steam generated in the furnace water walls passes through only once hence called ‘Once through

Supercritical pressure boilers’ The water in boiler is pressurized by Boiler Feed Pump, sensible heat is added in feed

heaters, economizer and furnace tubes, until water attains saturation temperature and flashes instantaneously to dry

saturated steam and super heating commences.

Slide 24

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 The Concept The mass

flow rate thru’ all heat transfer circuits from Eco. inlet to SH outlet is kept same except at low loads wherein

recirculation is resorted to protect the water wall system

Slide 25

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 Increased mass flow

through spiral waterwall tubing, or improved heat transfer through rifled vertical wall tubing. No fixed evaporator

end point No thick wall components Features Once Through Boiler Flow Diagram Evaporator Water separator

Slide 33

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 Features of Once

Through Steam Generator To ensure adequate mass flow rates through water wall, spirally wound water wall tubes are

used. Start-up and low load system up to 30-40% BMCR required. Feed water quality requirements are very stringent.

Can be designed for both sub-critical and super-critical pressures. Ideally suited for sliding pressure operation due to

the absence of thick walled components.

Evaporator system : Formed by a number of parallel tubes Tubes spirally wound around the furnace to reduce number

of tubes and to increase the mass flow rate thru’ the tubes Small tube diameter Arrangement ensures high mass

velocity thru the tubes

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 Vertical Furnace Wall

Design Vertical tube furnace walls will provide all the operational benefits of the currently popular spiral design while

significantly reducing the cost and construction time for the furnace and providing some reduction in pressure drop.

Slide 44

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 Vertical Wall Design -

Advantages The tubes are self supporting. Transition headers at spiral/vertical interface are avoided. Ash hopper

tubing geometry simplified Corners are easier to form Reduced pressure drop, auxiliary power

Slide 45

Enhancing Capacity – Empowering Nation Presentation on Supercritical Boilers 28 August 2012 Spiral Vs. Vertical Wall

Comparison Spiral Furnace System Applicable for all size units Benefits from averaging of lateral heat absorption

variation (each tube forms a part of each furnace wall) Simplified inlet header arrangement Large number of operating

units Use of smooth bore tubing throughout entire furnace wall system One material utilized throughout entire

waterwall system No individual tube orifices – Less maintenance & pluggage potential Vertical Furnace Wall System

Limited to larger capacity units. Less complicated windbox openings Traditional furnace water wall support system

Elimination of intermediate furnace wall transition header Less welding in the lower furnace wall system Easier to

identify and repair tubes leaks Lower water wall system pressure drop thereby reducing required feed pump power
