2.3 CUPOLA
FURNACES
The Council had
evolved cost effective scrubbing technology for air pollution
control in cupola furnaces having melting capacity less than 3 T/hr.
in 1994. This technology after through evaluation was approved by
the Punjab Pollution Control Board. This technology has so far been
replicated in more than 500 units in the State. The demonstration
units had also been setup in the States of J&K, Haryana, Jharkhand &
Bihar with funding from SIDBI, MoEF and DST, Govt. of India.
Salient Features:
v
No ID Fan required to run the APCD as thermal draft of
flue gasses overcomes the pressure drop.
v
Workers not exposed to CO emissions on the Charging
Platform.
v
Initial investment: Rs. 125000-150000
v
Negligible operation and maintenance cost.
v
SPM levels after APCD was found to be 210-275 mg/Nm3
against prescribed standards of 450 mg/Nm3
v
No water pollution as the scrubbing effluent is
totally recalculated.
v
Technology replicated in 550 units
Further the Council
has indigenously designed Energy Efficient Cupola Furnace (Divided
Blast Furnace). Demonstration units of these furnaces integrated
with APCD have been setup in the states of Punjab, Haryana and
Karnataka. These units have reported economic gain of Rs. 5-10 lacs
per annum on account of reduction in fuel (hard coke) consumption,
lime stone and energy besides control of pollution. The payback is
only 6 months.
Case Study:
Energy Efficient Cupola
Furnace integrated with APCD.
