Previous posts systematically described the process and modifications necessary to substitute compressed air in place of steam to atomize liquid wastes in a hazardous waste incinerator. Subsequent posts quantified the economic ramifications of these changes. Continue reading “Air vs. Steam Atomization Part 11 – Project Justification” »

Previous posts discussed incineration, atomization, stack losses and plant air production. From previous discussion, atomizing approximately 210 lb/min of liquid waste would require approximately 70 lb/min of atomization gas, which corresponds to 4200 lb/hr of steam or 933 cfm (70 lb/min / 0.075 lb/ft3) of atomizing air.
