RAPE SEED OIL BOILER,
NEW PRODUCT
The R Series year-round maximum condensing
boiler can now burn RAPE SEED OIL. Its proven
rotating cup burner gives instantaneous controlled
combustion with the boiler. Traditional components
(high-pressure pump, ignition spark and special
filters) requiring maintenance are eliminated.
The RAPE SEED OIL is kept like fuel oil in
an external or bunded vessel, then piped to
a pre-heat tank within the R Series boiler,
from which it passes to the burner. The RAPE
SEED OIL, a naturally grown fuel, burns with
the same maximum condensing efficiency as light
oil and natural gas.
The R Series year-round maximum condensing
boiler has two distinct heat exchangers, the
first of developed quality steel design and
the second of high-grade plastic design. The
flue gases leave the first heat exchanger at
temperatures below 90°C, and are then extracted
from the second condensing heat exchanger at
temperatures always below 50°C. For combustion
air entry temperatures below 30°C, efficiencies
are obtained which always exceed 92% up to
99%. These conditions apply throughout the
year in the United Kingdom
Fresh air is drawn either from a balanced flue
or conventional chimney inlet. It enters a
polypropylene condensing exchanger where it
is pre-warmed by the out-going flue gases.
The pre-heated fresh air is passed on to modulating
rape seed oil burner, where the air is burnt
with the oil in the combustion chamber. The
products of combustion are passed through the
main heat exchanger, then through the condensing
exchanger being cooled down by the incoming
fresh air and then leave the boiler at temperatures
between 15°C and 45°C. The R Series
year round maximum condensing boiler is most
efficient in mid-winter when the heat energy
requirement is at its maximum. |

PETCARE, LEEDS
Two 174kW ATLANTIC KDB
high powered high efficiency combination boilers were
installed in 2004 at the state of the art PETCARE,
Tingley, Leeds alongside Junction 28 on the M62. The
powerful combination boilers served both space heating
and two types of hot water supply - one for animals and one for staff and customers.
The combination boilers cover a range from 58kW to 232kW and develop up to over
4200 litres of 60 degrees Centigrade water in one hour.
Geoff Morgan of RODNEY ENVIRONMENTAL CONSULTANTS, Liverpool, who specified the
boilers says - Combis are very common on small output installations, but not
so common on large output jobs, A large part of the boiler power can be applied
to the hot
water without the need to install external exchangers and pipework - for a designer
this is a big plus, It is a minimal controls installation and, after several
years' experience, I can say that it is a reliable system." |

WRITTLE COLLEGE, ESSEX
Writtle College in Essex has recently installed Atlantics
R-series boiler as
part of their "green classroom" concept. A new 640m2 glasshouse, will
be used for teaching and for research and considers a variety of environmental
factors including the re-use of water, boiler efficiency and the type of fuel
used.
Writtle College is set in its own 220 hectare
estate with landscaped gardens, glasshouses,
equine units, an animal unit and a farm. These
practical facilities
act as a ‘green classroom’ to support the teaching. The courses include
a range of full and part-time degrees and postgraduate programmes. Subjects available
include horticulture and landscaping, design, floristry, business management,
conservation and environment, agriculture, animal and equine, leisure and tourism
and sport. The horticulture degree programme is the largest in the UK. The degrees
are validated by the University of Essex.
The glasshouse has five separate environment
controlled zones and the decision was taken to
install an efficient oil boiler that had the
flexibility to burn
either fossil fuel or a range of biofuel alternatives. This will provide an opportunity
to test the suitability of different heating fuels from both a practical and
financial perspective. The chosen boiler was Atlantic Boiler’s R Series
300kW condensing boiler. The boiler will burn carbon-neutral rape-seed oil, biodiesel
and used frying oil as well as conventional diesel oil. The R Series boiler,
placed in a series of carefully monitored installations since 2001, won the coveted
H & V award for technical innovation in 2005. The Installer is Hortimax Limited
of Elloughton, East Yorkshire. |

2007:
BUCKINGHAM PALACE, LONDON
Atlantic Boilers have reduced
the heating plant distribution costs for the first two
satellite
plant rooms at Buckingham Palace, London. The whole project,
which will take place over four summers, uses Atlantic
RS Turboflow plate heat exchangers which greatly increase
economic heat transfer. As a result the Palace's annual
energy bill will reduced by up to 8%. The installation
will also allow the consideration of carbon-neutral fuels.
Ron Harper, Deputy Property Manager, Buckingham Palace
has planned a progressive phased conversion programme
for the six satellite plant rooms at the Palace. Mr Harper
states "The movs will not only substantially cut
distribution energy costs, but will also allow the selection
of the most innovative replacement condensing boilers
for the central plant."
Large medium temperature hot water systems create large
distribution heat losses. With boiler flow temperatures
of 105ęC to 120ęC, and return temperatures from 90ęC
to 110ęC, these heat losses can amount to 15% of the
total boiler power required.
The need for these higher temperatures in the past is
reflected in the use of traditional shell and tube exchangers.
These exchangers convert the medium temperatures into
80ęC or lower space heating and 60ęC domestic hot water.
The latest Atlantic RS Turboflow plate heat exchangers
greatly increase economic heat transfer. This allows
the boiler flow temperature to reduce to 85ęC maximum
for space heating and 65ęC for domestic hot water. |

2007:
ROYAL DEVONSHIRE HOSPITAL,
BUXTON
The University of Derby have chosen to
restore the Royal Devonshire Hospital in Buxton.
The University plan contains an overall requirement
of sustainability and to that end the boilers
originally commisioned by Atlantic in 1988, were
in such good condition 17 years later that they
were retained and re-furbished using only new
controls.
In the development, English Heritage insisted
on as much use as possible of the existing fabric
within the Hospital, formerly the horse stables
of the Duke of Derbyshire. The requirements state
that not only should the Building be given a
new lease of life, but it should extend to the
local community and its economy. Existing routes
in the old masonry were used as much as possible
and, also, new cabling was installed to reduce
damage to the original fabric. Mechanical cooling
was limited to some, not all, TI-rich rooms -
most other spaces remained naturally ventilated.
Backed by substantial grants from the Heritage
Lottery Fund and other sources of finance, the
University resolved to turn the Building into
a Centre of Excellence for food, tourism and
learning.
The Atlantic boilers, originally commissioned
in 1988, were re-furbished by ACM ATLANTIC (associate
company of ATLANTIC BOILERS) and were among the
first generation of ATLANTIC high efficiency
and condensing boilers installed and commissioned
between 1982 and 1989. The boilers now serve
contemporary radiators and a large underfloor
heating system. |

2007:
BUSBY HALL,
NORTH YORKSHIRE
Grade II Listed Busby Hall
benefits from new oil condensing boilers despite buildings
restrictions. Atlantic Boilers have installed two oil
condensing boilers
in a Grade II* listed building in North Yorkshire. Two
R22/150 (range 95.3kW to 153kW) R Series Oil Condensing
Boilers were selected for Busby Hall, near Stokesley,
for the owner, Mr David Marwood, by Heating Design Services
Consulting Engineers, of York.
The boilers were chosen to fit within the restrictions
of an important listed building and this included off-loading
and positioning by Atlantic Boilers within the restricted
boiler space, plus the use of balanced flues to avoid
impingement on the building structure. The complete space
heating and domestic hot water system was carried out
by Jaydee Heating Ltd of Morley and Dundee.
With all the concern over energy conservation, it should
now be the case that all boilers specified today are
at least 92% efficient. ATLANTIC's range of condensing
boilers (rated from 7kW to 535kW) use outside air for
combustion air. As a result the whole annual space heating
energy (and any other energy requirement) will be met
by a boiler efficiency of greater than 92% and up to
99%. This will save up to 40% over conventional modern
boilers, and up to 20% over conventional condensing boilers.
Any additional boiler costs will be offset by savings
in fuel over a period of just 18 months to two years.
After that time, the savings go on and on. In addition,
the R Series condensing boilers flue gas temperatures
are ALWAYS below 50ęC and so low cost plastic flues can
make major savings. |

2007:
KENT COMMUNITY HOSPITAL, GRAVESHAM
Harrogate based OPERON
have selected ATLANTIC BOILERS to provide boilerplant
at the new Community Hospital in Gravesend. The three
535kW boilers enabled the installers, IEI Limited of
Southern Cross, Basingstoke to offer year-round condensing
with speedy changeover between gas and light oil, even
though the boilerhouse pipework operates at constant
temperature.
With all the concern over energy conservation, it should now be the case that
all boilers specified today are at least 92%GCV efficient throughout the year,
regardless of heating water return temperature. The R Series condensing boilers
supplied by Atlantic (with outputs from 10kW to 630kW) use outside air for combustion.
As a result the flue gases always leave the boiler at temperatures below the
dew point. This means the boiler efficiency will always be above 92% GCV and
frequently up to 99.5% GCV in mid-winter. |

2007:
HIGH PEAK COMMUNITY HOUSING,
BUXTON
Two 153kW ATLANTIC R Series New Generation Gas
Condensing Boilers were installed at Milton Court elderly
persons block (60 flats), Buxton in late 2006. Similar
boilers were fitted in the Marion Court and Alma Square
blocks.
The three ATLANTIC boiler systems provide weather compensated
radiator heating and fast recovery domestic hot water.
All the year-round condensing boilers have Technaflon
high-grade
rigid and flexible plastic flues which are
guaranteed for 20 years.
Mike Walters, who manages gas contracts for High Peak
Community Housing, selected the boilerplant. Mike says
' the 24/7 heating and domestic hot water energy demand
will be substantially reduced by the ATLANTIC R Series
Boiler. Also we have the possibility of simply changing
to a renewable fuel (as rape seed oil) in the future. |

2007:
LEWISHAM POLICE STATION,
LONDON
London based Rosser & Russell
have commisioned Atlantic Boilers to provide boilerplant
at the new Police
Station at Lewisham. The selection of the three 540kW
condensing boilers enable the mechanical and electrical
contractors to offer year-round deep condensing with
speedy changeover to either gas or light oil, even though
the boilerhouse pipework operates at constant temperature.
With all the concern over energy conservation, it should
now be the case that all boilers specified today are
at least 92% GCV efficient throughout the year, regardless
of heating water return temperature. The R Series condensing
boilers supplied by Atlantic Boilers (with outputs of
from 10kW to 540kW.) use outside
air for combustion. As a result the flue gases always
leave the boiler at temperatures below the dew point.
This means the boiler efficiency will always be above
92% GCV and frequently up to 99.5% GCV in mid-winter.
This type of condensing is termed “deep condensing” and
with the new generation condensing boiler it always takes
place for all types of energy supply. A significant feature
of this boiler is that it easily adapts to the different
fuels available. It is therefore suitable for dual fuel
firing and change of fuel in the future. An additional
advantage came from the smaller condensing flues with
were easily routed through the 5-storey building.
Chris Burton of Rosser & Russell said “The
cost benefit makes this option viable. Any additional
boiler costs will be offset by savings in fuel over a
period of just 18 months to two years. After that time,
the savings go on and on. In addition, the R Series condensing
boilers flue gas temperatures are always below 50ęC and
so low cost plastic flues can make major savings.” |
