Higher percentage of Chloride will result in corrosion inside bag filter

We suggest fuels like ground nut shell to be co-fired with fuel containing lesser potassium & chloride for better filter bag life Note: Bag filter is designed for above mentioned input parameters, bag filter guarantee will be null & void for any change in above input parameters.
