Elements of Two-Phase Flow in Fossil Boilers

  • Chapter
Two-Phase Flow Heat Exchangers

Part of the book series: NATO ASI Series ((NSSE,volume 143))

Abstract

This chapter is concerned with the key elements of steam-water two-phase flow in fossil-fired steam generators or boilers. Particular emphasis is placed upon the evaluation of large, coal-fired, high-pressure steam generators which are prevalent in electric utility power stations. This provides the framework for the common elements with unique characteristics of other steam generating systems treated as additions or exceptions. The boiler circuitry, furnace absorption, and general circulation evaluation are first reviewed. Then the key limiting criteria are addressed including instabilities, heat transfer with particular reference to critical heat flux, steam/water separation, and boiler drum. Factors affecting other boiler designs are then outlined.
