India has many no of renewable energy resources. In that Biomass Gasifier plays a major role as an alternate energy
source. But it facing lot of practical problems on operation due to shortage of manpower and also several problems may
happen in these gasifiers. To overcome the above problems we go for automatic control systems in this gasifier. Therefore we
can neglect the human efforts, errors and operators of the gasifier won’t get affected by the out coming gases from the
gasifiers due to this automation. The gasifier itself works according to the program which we have given. Automation is done
in the miscellaneous function, fuel feeding system and all biomass gasifier control system by using PLC (Programmable Logic
Controller). And then we develop the ladder logic program for sequence of operation in gasifier control system. In this system
the ladder logic function is programmed by using INDRALOGIC software and the hardware component of PLC is Rexroth
Bosch product.
Keywords: Programmable logic controller (PLC), Biomass gasifier, Indralogic.

2. Que é un caligrama?
O caligrama é un poema, frase ou palabra cuio
propósito é formar unha figura acerca do que
trata o poema. A isto podémoslle chamar
(poesía visual).
3. Características
● Caracterízase porque a imaxe creada polas palabras
expresa visualmente o que a palabra di.
● Nun poema, neste, maniféstase o tema presentado
polo texto do poema.
● Os caligramas úsanse principalmente para divertir ao
lector e facerlle ver que é o que quere transmitir o
poema a partir da imaxe creada.
4. Cando/Onde nace o caligrama?
Na modernidade deuse coas Vanguardias de
principios do siglo XX e máis concretamente co
cubismo literario e os posteriores Creacionismo e
Ultraísmo; O poeta cubista francés, Guillaume
Apollinaire, foi un famoso creador de caligramas. O
poeta creacionista chileno Vicente Huidobro xa
había incluído o seu primer caligrama, “ Triángulo
armónico”, no seu libro Cancións na noite (1913).
Con Apollinaire os caligramas póñense de moda
nas primeiras décadas do siglo XX.
5. O caligrama en España.
A literatura hispánica conta con interesantes
autores de caligramas; entre outros, os españois
Guillermo de Torre, Juan Larrea y Gerardo Diego.
6. O caligrama noutras culturas
As grafías árabes
serven neste caligrama
antigo para formar a
imaxe do paxaro
bebendo da fonte.
¿Non recorda a
Apollinaire e a súa
“Pomba apuñalada e o
surtidor”?
