Oil Gas Coal - N/A, N/A, N/A
1st Call performs precision blasting with smaller charges. By using smaller charges this lowers the possibility of damage from over-pressure. The amount of slag removed per shot will depend on the makeup of the ash. Blasters start out with small charges and increase the size of the charge as required to remove the slag safely.The principal areas serviced are the main firebox (walls, burners, and pendants), generating banks, economizers, back passes, and convection passes. 1st Call is also capable of using explosives in other areas where ash may build-up such as; silos, service vents and ash hoppers.
