10 tie Editor Of tks Haraiiaa Gasstfs;
SIR.-we have read with much interest the letter
which appeared in your impression Of the Esd August
under the signature &C. F. H." on the subject Of
a. Fuel on PlAntatOn,' and as sole prOpriet0rs Of
Head and SshsuiOths patent for burning vegetable
substances in steam boilers, to whish your
POndcnt especially refers. We think few words on
the subject may not &c unin,srssng your readers
The original invention was 6rsi publiely exhibited
At Vienna in 1873. and especially adapted for
burning straw in portable and axed steam engines.
which were intended for use in Russia. Hungary.
Roumania and other countries where coal is not in-
dgenOus and wood is scarce and in some parts not
be obtained.
Ttsse engines enabled the farmers and small manu-.
factursrs to use steam power generated from fael
which cost them almos, nothing. AID which was al
ways at hand, and to such an extent has this boon
been appreciated that nearly 400 engines Of different
sizes have been manufactured on this patent since
1873 and an average saving of from 81 los Cd to
- Os Cd per diem has been effected by their use.
Besides being used for burning straw these furnaces
have been successfully employed for burning reeds.
maine stalks. aud brush wood and many engines
built this patent are work in Egypt, using no.
thing but cotton stalks fuel. producing great
economy where coal is 81 per ton.
In all the patent furnaces constructed to burn the
above named vegetable products the theoretical prn
eple adopted has been TO hold the matter be burn
Cd in suspension in the furuance allowing TO aoa
lightly the burning ashes. thus permitting sud-
Gent space for the circulation of the air necessary
for free eembu stion the tune the half barn.
fuel is always stirred up and kept in motion by the
injection Of thin layer Of fresh fuel whsh is forced
continuously toto the furnance by Of the ap-
paratus which is worked by the engine.
We fear to take up too much of your valuable
space with general description Of the mechanical
arrangement Of the apparatus, and have therefore
enclosed you pamphlet describing the invention,
and containing accounts Of various scientific trials
and experiments which have taken place with il in
EuglAnd and abroad, fros which you can extract
whatever you think will to interesting to your
readers.
Oar patent has been successfully tested with
cane trash in Egypt in the presence Of his Highness
the khediVe by one Of our partners, and we enclose
drawing Of design for adapting the patent to the
furnaces Of the large boilers Of the factories to His
Highness.
In this apparatus the cane trash, which is first
partially dried in the SUM- is placed in an inclined
iron trough, one end Of which is fixed to the frame
carrying the two tOOthed rollers which is attached TO
the east iron furnanee front. The cane trash falls
by its own gravity to the rollers which deliver it 70
4
dead plate Immediately under the furnance mouth
This serves distribution for the fuel before 1t
reaches the crate bars, which are also inclined and
with wider air spaces than for al or wood me-
ch 'nieal priker acting the whole CRATE at the
same time is sometimes employed for keeping the air
spaces free from sicious deposits
When good fire has been made up 10 the crate a
thin stream Of fresh trash is continuously in
jeeted into the furnace by means Of the rollers
which may either be turned by hand or steam power
aud the uneonsumed fuel gradually forces the half
burnt and burnt trash towards the cad of the
furnace where the greatest amount of combustion
takes place.
One great advantage Of this apparatus is that in
stead Of throwing the fuel to the top Of the fire.
as has hitherto been the CUSTOM in which case all
vegetable substances act a sort of damper our
patent arrangement forces the fresh cane trash into
the centre Of the coolest part of the burning mass
thus supplying the fire with fuel without checking
the evolution Of the gases produced by combustion in
the middle and and Of the furnanee at the same time
the whole mass is kept III 4 state of slight and eou-
tinual motion which is necessary to the proper
combustion of vegetable substances as the jerking
movement Of farmers pitehfOrk is to the proper
preparation of a manure heap.
We hope you will pardon the length Of our letter
and If any Of your readers would ike further in.
formation upon the combustion of vegetable sub
stances and cane trash aud will send US drawings of
their boilers shall be happy to adapt our inven-
ton to their special requirements.
Yours obediently
RASsoNEs. SINS HEAD.
I'VE would add that we have received In connec-
iion with tue above letter number of catalogues,
aud also plans in which the apparatus is fully illus
rated, all of We shall be happy to exhibit to any
who feel interest 10 this subject. Ed
