Coal-Fired Industrial Boiler Inspection Guide

The prac- tical steam-output limit of boilers equipped with mechanical stokers is about 400,000 Ib/h (although many engineers limit the application of stokers to somewhat lower steam capacities). Within their capacity range, mechanical stokers are well suited for the production of steam or hot water.
