A visit to the Municipal
Technical
Institute Building in Belfast was made by Group Members Mike Barber and Frank Ferris in September to find out whether earlier comments made that a steam engine was still operating in the building providing power, were right. What they found was astounding The original 15hp - 100psi. reciprocating horizontal steam engine has been in daily use driving the two very large centrifugal fans This steam engine powered plenum ventilation system could well be unique. The Heritage Group should send a challenge to find out whether there are any other original steam engines still in daily use. |
The survival of this steam engine is due
to the dedication of the Plant Engineer for the
building, who has organised the regular
maintenance and kept
all
the services plant in excellent working order.
The plenum ventilation system has several other interesting features, some of which could be the only surviving examples from this Edwardian time period. Disk humidifiers / washers, belt driven from the steam engine. Waste steam feed water pre-heater. Branch duct air re-heaters fed from a one-pipe heating circuit. Branch duct volume control dampers. |

The
Christmas Lecture for the Heritage Group was arranged as a
joint
meeting with dinner at the Rumford Club. They invited group
members
to join them at their St Stevens Club, Queen Anne’s Gate London for
their
December meeting. Two after dinner speakers gave presentations. The
first
was given by Dr Frank James of the Royal Institution who
gave
a talk on Humphrey Davy and his assistant Michael Faraday who then went
on
to become the eminent Engineer and distinguished Lecturer at the Royal
Institution. The second talk was given by group Vice-chairman Paul
Yunnie who talked about the life and exploits of Benjamin
Thompson, Count Rumford. A very enjoyable evening was had
by all the attending Group Members.
The
AGM and Group Committee meeting was held in the preceding
afternoon.

The Group has been told of an old
Methodist Church circa. 1830 in Truro Cornwall a Grade 2 listed
building which is due to be refurbished. The existing ventilation
system in the Church is
provided by a venturi sited in the roof above high level gas
chandeliers.
The resultant stack effect forms the passive ventilation. The fresh air
entry route into the building is
through
low level air bricks and
window
openings. The Consultant Jerry Kent
(contact
01271 - 323765) would like to put
the
original system back into
commission
and therefore would welcome comments from anyone who can
confirm
whether it is safe and
satisfactory.
