Plugging Firetubes - The National Board of Boiler and

through the boiler. A plugged tube reduces the cross sectional area of the flow path. The reduction in area reduces the flow through the boiler and increases the pressure drop across the boiler. The increase in pressure reduces the air output of the blower (forced draft or induced draft).

About » Babcock & Wilcox

When Stephen Wilcox first avowed that "there must be a better way" to safely generate power, he and George Babcock responded with the design for the first inherently safe water-tube boiler, and the company was born. This challenge to continuously improve endures today.

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler heat exchanger effectiveness is specific boiler thermal efficiency, which is converted to heat energy from the fire side to the water side. In addition, thermal efficiency is seriously affected by soot formation/scale formation on the boiler tubes. 3.5.3.6.3 Indirect and direct boiler efficiency
