1. STATIC / FLUID BED DRIERS: |
|
Conventional
drier models used for drying applications of various edible
and non edible materials. The drier can effect moisture removal
upto 20 to 30 % composition in the parent material. These
are predominantly low temperature models , the temperature
varying from 100 to 200 Deg C. The size of the drier is finalized
based on the physical moisture to be removed based on the
throughput requirement. The type of the drier will depend
upon the drying needs. The options will be either static bed
or fluid bed applications , either on batch mode or on line
mode. The throughput range can vary from about 100 Kg/hr to
about 1000 Kg/hr. The material selection will be based on
temperature criteria and application requirements. The system
will be complete with dust separation units.

FLUID BED REACTORS: |
|
Reactors are process vessels
used in the application areas such activation of various materials
ranging from carbon , alumina , silica etc. These are effectively
high temperature models , the temperature varying from 800
to 1200 Deg C. The size of the reactors will depend upon the
throughput requirement. The reactors will be on line continuous
mode operation. The reacting medium can be either steam or
flue gas. The method of generating the medium can be process
steam boilers or external combustion units. The throughput
can vary from about 25 Kg/hr to about 250 Kg/hr. The material
selection will be based on temperature criteria and application
requirements. The system will comprise of dust separation
units , exhaust heat recovery systems as the case may be.

3. BAGASSE DRIERS:
|
|
Bagasse
driers have been developed as a special application drier
to remove moisture from raw bagasse from about 50% to about
40% . The drier shall comprise a flake separation unit , a
bagasse drier fluid bed unit which acts as a conveyor also.
The heat for drying is taken from exhaust flue gas from boiler
or low pressure steam.

MICRO & MINI STEAM TURBINES:
|
|
The
process industry requires both power for running and process
steam for heating or drying applications. It has a general
practice to design combined heat and power plants (CHP Plants)
to meet the demands. The CHP plants normally comprise of a
process boiler and a back pressure turbines. There are industries
where process steam alone is generated at a standard 10 bar
pressure and used for process needs after suitable pressure
reduction. The above options have not been a optimal heat
utilization method as a lot of heat goes unutilized. The best
option is to consider micro or mini steam turbines to effectively
carry out the above needs. The micro turbines vary in rating
from about 50 KWe to about 300 KWe. The inlet conditions can
be upto 32 bar and 350 Deg C with the exhaust at about 2 to
5 bar thus meeting the small process needs while generating
useful power in parallel.
The micro turbine is ideally suitable in distilleries, chemical
and small process industries. The mini turbines come in the
range of 1000 to 2500 KWe rating. Since a commercially viable
condensing turbine with or without extractions was not made
earlier, the current designs fulfills the slot successfully.
The inlet pressure conditions can vary upto 63 bar and 480
Deg C, The extractions can suit process needs. While steam
heat is optimally used the cost of installation is also controlled
to meet the economic viability of the industries.

SOLAR POWER BASED COMPONENTS: |
|
Solar
power is a clean source of energy available from day memorial
but effective utilization of solar power was not specialized
till date. However in the last few years the world has seen
an explosive growth in the above area. The application is
very wide and include but not limited to:
|
 |
Solar water heaters |
|
Solar
lighting systems (garden / street lights) |
|
Solar
water pumping systems |
|
Solar
power plants using PV cells |
|
Solar
power based traffic booths / bus shelters / advertisement
boards etc |
|
Solar incubators |
|
Solar
