Eco-Friendly Cokeless Cuploa
Introduction
NML has developed an environment friendly Cokeless Cupola using either low sulphur light diesel oil (LDO) or natural gas LPG which not only reduces emission level of the suspended particulate matters 9SPM) but also the sulphur dioxide within Central Pollution Control Board's stipulated limit of 150 mg/m3 and 350 mg/m3 respectively. In addition it gives liquid metal worth of making high value spharodized gray (S.G.) cast irons.
Major Raw Material
Pig iron, Fuel (LDO or Natural gas or LPG) and flux for slag making
Major Plant Equipment
The furnace is similar to coke fired cupolas except that there is a water cooled grate over which ceramic balls are placed to take the load of charge and provide porosity for flue to go up and melt to flow done. Liquid or gas burners are fixed below the grate to impart necessary heat to melt the metal & slag.
