Description:The removal of fine particulates from flue gas at elevated temperature is a difficult challenge. Solid waste incinera- tors, for example, can emit more than 0.2 lb/M-BTU of fuel fired. Many of these incinerators have little or no heat recovery and discharge high temperature flue gas to the atmosphere. Collection of the so-called respirable dusts, consisting of particles below about 10 microns is quite difficult in these applications.
The core separator is an innovative, high-efficiency dust collector, which can separate very fine particles. It has the ability to overcome some major limitations inherent in conventional mechanical collectors, namely turbulence and particle reentrainment. It provides high collection efficiency with simple and reliable operation. Proof-of-prin- ciple of the core separator has been demonstated with flow models at ambient temperature. However, a broader Phase I feasibility analysis is needed to demonstrate that the same performance is attainable at high temperature. The feasibil- ity analysis is divided into two areas: (1) construction of a hot model, and (2) experimental testing and data analysis. A prototypical unit is envisioned for Phase II.
