1.1 Bituminous And Subbituminous Coal Combustion

The boiler and furnace are contained in the same shell in a Scotch or shell boiler. Vertical firetube boilers are typically small singlepass units in which the firetubes come straight up from the water-cooled combustion chamber located at the bottom of the unit. A firebox boiler is constructed with an internal steel-encased, water-jacketed firebox.

Water for the Boiler | Spirax Sarco

Water-tube boiler plant. Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate.

Boiler Feedwater - an overview | ScienceDirect Topics

Boiler feedwater is then treated in the deaerator to remove dissolved gases (mainly oxygen and carbon dioxide) as these dissolved gases would otherwise cause corrosion in the boiler systems, and a final chemical treatment agent is applied to further remove oxygen after the deaeration (BETZ, 1991). From: Handbook of Process Integration (PI), 2013.

Boilers

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Finding the Root Cause of Boiler Tube Failures

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water
