# Destruction & Removal Efficieny (DRE) Formula & Calculator

## Hazardous Emission Rate to Air Calculation

Win - Mass feed rate of a particular POHC(kg/h)
Wout - Mass emission rate of the same POHC(kg/h)

Destruction & removal efficieny (DRE) calculator - formula & step by step calculation to measure the amount of hazardous constituents that may be emitted to the air from an operating incinerator. The mass feed rate of a particular POHC Win in lb/h, mass emission rate of the same POHC Wout in lb/h & POHC is principal organic hazardous contaminant are the required elements to perform DRE calculation in evironmental engineering.
