PARAMETRIC LIMITS OF EFFICIENT USE OF A CENTRIFUGAL WATER ATOMIZER IN CONTACT WASTE-GAS HEAT-UTILIZATION UNITS
The relation for the limiting temperature of water heating in a contact gas–droplet-type apparatus with a centrifugal atomizer has been determined experimentally in relation to the conditions of utilization of heat of power plant wastegases. Investigations were carried out in the range of excess water pressures in front of the atomizer 0.2–0.6 MPa and of the volume fraction of steam in the vapor–gas mixture at the inlet of the apparatus from 0.02 to 0.45. The possibility of using the obtained dependence for calculating the limiting values of the vapor–gas fl ow parameters that limit the range of effi cient operation of the contact apparatus with steam condensation and in the absence of
heated liquid droplet evaporation is shown.
