POWER

M/s Vaswani Industries Limited has installed an 11.5 MW capacity power plant in addition to the Sponge Iron and Steel Division.

We utilize flue gas, and form steam from our 03 Waste heat recovery boilers (WHRB), in the form of renewable energy from 100 TPD sponge iron kilns. We have also installed an AFBC boiler in which a maximum amount of dolochar (By Product of DRI production) is used as fuel. The Electricity Generated in the captive power plant is used by the steel Melting shop (SMS). This process of utilizing waste heat to generate into electricity is extremely beneficial for the environment.

SPONGE IRON

Sponge iron is also known as Direct Reduced Iron (DRI), is the product of reducing iron oxide in the form of iron ore into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Sponge iron is used in the iron and steel industry as a substitute for scrap in induction and electrical arc furnaces.

Process
Sponge iron making is a process in which iron ore lumps (5mm-18mm size) are tumbled with a ‘select’ grade of coal & dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished product bunkers prior to dispatch. The process entails a direct reduction of the iron ore (i.e. removal of oxygen from the ore) in solid state to metalize the ore at a ‘critical’ temperature to make this possible.

The basic reduction reactions in a coal based DRI process is as follows:-
C+ O2 = CO2
CO2 +C = 2CO
3Fe2O3 + CO = 2Fe3O4 + CO2
Fe3O4 + CO = 3FeO + CO2
FeO + CO = Fe + CO2

We are manufacturing DRI in following Specifications:

Parameters/Material	DR Clo	Pellet
Fe(m)	82(+-) 1	80 (+-) 1
Carbon	0.15	0.15
Sulfur	0.035	0.035
Size	0-20 mm	3-20 mm
-1(mm)	‹20%	-
