Mini Blast Furnace with Air-Pollution Control Device:-
A Mini Blast Furnace with Air Pollution Control Device is a basic coke fired furnace for secondary re-cycling , which is being used from decades worldwide due to low capital and recurring cost, easy to install and operate. It produces low antimony lead (soft lead ) at low temperature.
Mini Blast Furnace is brick lined structure with fire brick oven. Raw material along with fuel (coke) is fed into furnace manually and air is supplied by the F.D. Fan. Temperature of the furnace is achieved at desired level, after specific time molten metal starts flowing in the pit . After that slag is separated and molten metal is poured into moulds for the final shape of the product. This process is continued up to the desired time. Whatever the flue gases generated during the operation are sucked through metallic hood and flow to air pollution control device for treatment. The flue gases which are toxic in nature and need appropriate and adequate air pollution control system for their treatment.
