INTRODUCE DUVANOV METHOD IN BRICKWORKS -- Berlin, Taegliche Rundschau,
6 Mar 51
As the result of experiments carried out by the Zehdenick I and Milden-
werk II brickworks, a rapid-firing process for the production of bricks
has been adopted by brickworks in Brandenburg and Mecklenburg.
The process, the Duvanov method devised by Pavel Duvanov of the USSR,
is to be introduced in all brickyards of the German Democratic Republic.
At the Zehdenick plant, the characteristic method used in the Duvanov
process for arranging the base for stacking the bricks was modified so that
three bases are drawn together and a slit, four bricks high, runs the en-
tire length of the burning channel. Above this base the bricks are stacked
with air spaces between them so that only 270 bricks per cubic meter are
stacked compared with the 325 bricks formerly stacked in the same area --
a reduction of 17 percent. The uniform distribution of coal throughout
the firing some was made possible by using a rotary feed method and by
reducing the stoking time from 60 to 15-20 minutes.
These improvements made it possible for the fire advance (the
which the fire advances in 24 hours) to increase by 55 percent.
quently, production of the kiln has risen from 170,000 to 240,000 bricks
per week. The complete firing period of the kiln has been reduced from 12
to 7.8 days. Coal consumption has been cut from 330 to 275 kilograms per
1,000 bricks, a saving of 16.7 percent.
The new method has been introduced with even greater success in the was mad

15 minutes. A considerable acceleration of the firing schedule raised the
weekly production from 172,000 to 253,000 bricks, with a coal saving of
17 percent. The Mildenwerk II plant was obliged to operate a second shift
of the furnace crew to be able to keep up with the rapid-firing schedule.

At the Hecklingen Brickworks it was pointed out by activist Sgraja,
who introduced the Duvanov method in that plant, that the precedents
established by certain brickworks in the various Laender must lead to
the adoption of the new rapid-firing process by all brickyards of the
Gurman Democratic Republic. He stated that Hecklingen had been able to
up its firing schedule by 84 percent and that this figure was to be raised
to 120 percent. A further reduction of costs is to be effected by the use
of locomotive cinders, coke lust, and other waste fuels.
In line with the Ger-an Democratic Republic's system of industrial
competitions, Mildenwerk iI has challenged Zebdenick I to compete for
increased production and saving of fuel by application of the rapid-
firing process. Other competitions have been entered into between Branden-
burg and Mecklenburg plants.
TO PRODUCE PORTLAND CEMENT -- Berlin, Taegliche Rundschau, 12 Jun 51
The cement works at Rummelsberg is turning out hydroment, a cement-
type binding agent made of lime and ash waste obtained at the nearby
Klingenburg power plant.
Production of Portland cement is to begin in the near future at the
rate of 80 tons per day, and this output is to be doubled by the end of
1951.
