Our mission is to engineer the EMPIRE Water Tube Boiler to meet the exacting
demands of the mills' latest requirements. |
| |
|
The need for a USER and ENVIRONMENTAL friendly
Steam Boiler for firing BIOMASS Fuel cannot be
overemphasized. Traditional methods |
|
of boiler sizing and evaluation is no longer
valid. |
|
|
Latest Research & Development in Palm oil Milling technology has
shown that changes in the FFB Sterilisation Process, higher electrical power
demand, stringent environmental emission standards and the use of empty bunch
fibre (EFB) as fuel require new method in Boiler Evaluation. A shortage of
manpower demands more automation in Fuel Feeding, Automatic Boiler Control and
Continuous Ash Discharge. |

"Atlas" vertical boilers are designed and
constructed to the latest |
|
ASME
Code. All "Atlas" vertical boilers are approved
by the
|
|
Department of Occupational Safety and Health and
each unit
|
|
undergoes rigorous inspection during the
fabrication stage of the |
|
boiler. The inspection is carried out by an
approved Third Party
|
|
|
Inspection
company. |

The "Combi"
design is a composite construction that combines
the |
|
best
features associated with both fire tube and
water tube boilers. |
|
It
comprises of a water tube furnace of "Membrane
Wall" construction |
|
and a
shell and tube section that provides convective
heating |
|
surface. The former ensures gas tightness,
increased heat exchange
|
|
|
efficiency
and minimum refractory work, the latter provides large
water volume and steam |
|
release area. |
|
|
|
Fuel |
The boilers are designed to fire various types of Biomass fuel
and can be supplemented with fossil fuel. The nature of fuel and
degree of mechanization will determine the type of fuel feeding
system |

Design and construction |
|
The
boiler is an all welded horizontal three pass,
wet back fire tube |
|
design, to the requirements of B.S.2790, 1989,
supplied as a |
|
packaged and supplied as a package unit with
burner and ancillary |
|
equipment fitted before dispatch. |
|
1. Large Thermal Storage
Large water content in boiler to maintain constant pressure of
boiler. Large steam / water surface to give low escape
velocity & hence to ensure drier steam.
2. Lower Tube Metal Temperature
The completely water-cooled combustion chamber increase the
proportion of radiant heating surface, lowering the gas
temperature into the convection tubes and increasing boiler's
overall fuel to steam efficiency. Combustion chamber acts as
primary heating surface as well.
3. Concentric furnace designed. Better hot water circulation
4. Accessibility
Boilers are fitted with a 420 mm X 320 mm manhole welded into
the top of the top of the shell and two head-holes in the bottom
of the shell where access is possible.
5. Less sensitive to poor feed water quality
Research and tests shown that due to lower metal temperature the
boiler is more suitable for use with feed-water of poorer
quality.
6. Minimum refractory at Burner quarl hence reduces incidence of
refractory works.
7. Third pass plain tubes fully expanded
Second pass plain tubes expanded at one end & welded at
combustion chamber end with "J" prep.
8. Quality & proven burner is employed to do the duty.
It is "user friendly" and easy for maintenance.
9. Water level controls and alarms are fitted as follow:-
Dual control arranged to cut out the burner and give alarm at
first low water level and also to control the feed water pump.
Single control arranged to lockout the burner and alarm at
second low water level.
