Process design aspects, such as
• Steam parameters
• Excess air ratio
• Flue gas outlet temperature
mainly define the efficiency of the boiler plant.
Mechanical design aspects, such as
• Vertically or horizontally arranged convective heating surfaces
• Bottom or top suspended boiler
• Overall plant size
mainly define the plant layout.

Horizontal Vertical
Boiler Concept 3 vertical radiation passes, convective heating surfaces in a
arranged horizontally in 4th pass.
4 vertical passes. The 1st pass as empty radiation pass, 2nd radiation pass evtl. with
platen heating surfaces. Convective heating surfaces in 3rd and 4th vertical passes.
Area required Approx. 20-30% more of boiler length. Additional space required for sootblowers in terms of distances
between two boilers and overall plant width.
Overall height 3 radiation passes allow for lower boiler height.
The vertical concept increases the height of the building.
Extraction of ash About 6 or more hoppers + rotary locks or double flaps and a collecting sifting conveyor.
The minor amount of ash is carried over to the FGC system downstream
of the boiler.
Heating surface cleaning
Pneumatic rappers with frequent operation. Low energy
consumption.
Steam sootblowers with high efficiency. Operation once per shift. Steam consumption slight negative impact on rated power output of
turbine/generator.
Horizontal versus Vertical convective Pass

17
Bottom Supported Top Suspended
Steel Structure Separate steel structure for boiler house required.
Top suspended boiler allows for integrated steel structure for boiler
house.
Grate suspension
For small units bottom suspension of grate and boiler is appropriate since
there is only little compensation required.
Also very large grates can be bottom suspended due to high loads.
Top suspended boiler allows for top suspended grate
->no difference in thermal expansion -> no compensation required. -> Good excess under grate.
Waste Feeder Large units rather use standing waste feeder due to high loads of
waste in the chute.
SBENG´s standard layout with top
suspension of feeder, grate and boiler for plants from 35 MW
up to 110 MW.
Furnace Adiabatic combustion chambers can be bottom suspended due to
high loads of refractory.
