The average number of grains of Sulphur (other than sulphuretted
hydrogen) in 100 cubic feet of gas was
for the whole year ended 31st March, 1911, 277.
This is a satisfactory average being rather less than that of 1909
(29.5 grains) although slightly higher than that of 1910 (24.0 grains).
The monthly averages (Table I.) vary between a minimum of 24.0
(September, 1910) and 30.6 grains (February, 1911) while the weekly
averages (see Sulphur curve, Table III.) shew a minimum of 207
(March, 1911) and a maximum of 34.8 grains (February, 1911).
Sulphur.
Pressure.
The pressure has not been excessive at any time during the
year ended 31st March, 1911. In Table I. it will
be observed that with an average for the whole
year of 2.8 inches, the minima and maxima monthly averages were
2.7 and 3.1 respectively.
Sulphuretted
Hydrogen.
At no time have I found this impurity in the gas during the
Past year.
Proposed New
Burner and
Calorific Tests.
In my last Annual Report, for the year ended 31st March, 1910,
I called attention to the Gas Companies (Standard
Burner) Bill, in which the Wandsworth and Putney
Gas Company and the Brentford Gas Company proposed to join,
having presented a report on the same to the Council, dated 31st
December, 1909. In that report I stated that there seemed to be
no valid objection to the adoption of the proposed new Standard
Burner (the Metropolitan Argand Burner No. 2) by the Wandsworth
and Putney Gas Company. At the same time I strongly urged
the institution of Calorific Power Tests, for information, with a
view to the ultimate adoption of a Calorific Power Standard.
Eventually, however, the Wandsworth and Putney Gas Company
withdrew from the Bill in March, 1910, and, to my regret, the matter
dropped.
Since that date the Brentford Gas Company having adopted
a new Burner, very similar to but not identical with the Metropolitan
Argand No. 2, successfully upheld in the High Court, in
proceedings taken by the Chiswick Urban District Council, their
right to use the same for the testing of their gas.
