Improvements in the Manufacture of Peat Fuel.
I GUSTAFOA ANGEL of Jonkoping in the Kingdom of Sweden, Married
Woman do hereby declare the nature of this invention to be as follows:-
By the methods hitherto in use for producing from peat a fuel approaching
coal in solidity and value the peat has been heated either in kilns or retorts without
admission of air so that it is charred and the generated products of distillation
have been in various ways recovered separately to be added to the peat fuel either
as an adhesive or to increase the value of the fuel as such,
According to my invention on the contrary the turf is heated in closed chambers,
retorts, kilns or the like without outlets for the gases and there undergoes charring
at a comparatively low temperature so that after the end of the charring all the
usual products of distillation are found again in the finished fuel.
The peat to be used must have been freed from the greatest portion of its water.
Such peat is introduced into suitable apparatus, which are then shut up and warmed
from outside in any suitable manner to a temperature in the charring room varying
between 50 and 400° centigrade during a time of 1 to 6 hours according to the
quality of the peat.
may
The charring being ended the apparatus is either left to cool slowly or it be
quickly cooled in any suitable manner or the finished fuel still warm may be raked
out and cooled.
The fuel produced according to my invention is more or less glossy, hard and
clean to the touch and is nearly equal to coal not only in appearance but in warming
power.

Improvements in the Manufacture of Peat Fuel.
I, GUSTAFOA ANGEL, of Jonkoping, in the Kingdom of Sweden, Manufacturess,
do hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
By the methods hitherto in use for producing from peat a fuel approaching coal
in solidity and value, the peat has been heated either in kilns or retorts without
admission of air so that it is charred and the generated products of distillation
have been in various ways recovered separately to be added to the peat fuel either
as an adhesive or to increase the value of the fuel as such.
According to my invention on the contrary the turf is heated in closed chambers,
retorts, kilns or the like without outlets for the gases and there undergoes charring
at a comparatively low temperature so that after the end of the charring all the
usual products of distillation are found again in the finished fuel.
The peat to be used must have been freed from the greatest portion of its water.
Such peat is introduced into suitable apparatus, which are then shut up and warmed
from outside in any suitable manner to a temperature in the charring room varying
between 50 and 400° centigrade during a time of 1 to 6 hours according to the
quality of the peat.
The charring being ended, the apparatus is either left to cool slowly or it may

..
The fuel produced according to my invention is more or less glossy, hard, and
clean to the touch and is nearly equal to coal not only in appearance but also in
warming power.
"
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
:-
..
"
In improvements in the manufacture of peat fuel charring the turf or peat
previously freed from the greatest portion of its moisture in closed chambers and
heating the same from outside and so preventing the escape of gases.or other
*products, substantially as described.
