This is Pressac's Document G2b, a translation of Document G2a.
A reproduction of G2a is available at:


"Before charging the two hearths with coke, the two furnace dampers
and the main rotary damper in the chimney must be open.

"The fire can now be lit and maintained, being sure to open both
secondary openings to the right and left of the cinder removal doors
(of the coke furnace).

"Once the cremation chamber (muffle) has been brought to a good red
heat (approximately 800 (deg) C), the corpses can be introduced one
after another in the cremation chambers.

"Now the pulsed air blower situated to the side of the furnace should
be switched on and run for about 20 minutes, ensuring that the two
cremation chambers do not receive too much or too little fresh air.

"Regulation of the fresh air is by means of a rotary valve in the sir
duct.  In addition, the air intakes, to the right and left of the
chamber doors, should be half open.

"As soon as the remains of the corpses have fallen from the chamotte
grid to the ash collection channel below, they should be pulled
forward towards the ash removal door, using the scraper.  Here they
can be left for a further 20 minutes to be fully consumed, then the
ashes should be placed in the container and set aside to cool.

"In the meantime, further corpses can be introduced one after the
other into the chambers.

"The two coke furnaces must be fed with fuel from time to time.

"Every evening, the furnace fire bars must be cleaned of clinker and
the cinders removed.

"In addition, care must be taken that at the end of operations, as
soon as the furnace, having burnt everything is empty and no coals
remain, that the air valves, doors and damper are closed, so that
the furnace does not cool.

"After each incineration, the temperature rises in the furnace.  For
this reason, care must be taken that the internal temperature does
not rise above 1000 (deg) C (white heat).

"This increase in temperature can be avoided by introducing
additional fresh air." (Pressac, 136)
