Coal Fired Industry Boiler Enamel Air-preheater

Investigations on the Ash Deposit Formation of Tubular Air

A study was undertaken of the air preheater ash deposit in a 140 MW coal-fired traveling-grate boiler. Several ash samples were collected in the selected regions of the air preheater along with samples of the feed coal. The ash samples were examined using combination of ash X-ray fluorescence (XRF) and X-ray diffraction (XRD) analysis to determine the chemistry and mineralogy.

Coal-Fired Industrial Boiler Inspection Guide

Tangential or corner-fired pulverized-coal-fired boilers tend to pro- duce less NO than wall-fired units. s The particulate emission rate is a function of the coal ash content and the firing method. Pulverized-coal-fired boilers emit between 70 and 85 percent of the ash in the coal as fly ash.

Challenging Efficiency Limitations for Coal-Fired Power

Promoting boiler efficiency: This is accomplished primarily by reducing the amount of excess air and increasing the use of the flue gas heat. The designed efficiency for bituminous coal-fired boilers has reached ~95%. This can be limited by the burn-off rate and coal type, and especially by the sulfur content.
