Boiler Heating Surface Area in Sq-Ft Vs. Gross Output BTUH

The boilers estimated max feed rate can then be ballparked via: Max Feed Rate (Lbs.) = Input BTUH/12,300 This might come in handy for the case where an older stoker boilers sq-ft of heating surface is known or can be measured, and where no other information is known for it.

Heat Transfer Surface Fouling in Boilers

Fouling in boilers is dependent on the type of boiler design and the fuel being fired. The main factor that leads to fouling in a coal fired boiler is the increase in percentage of the low melting constituents. Fouling in boiler heat transfer area is different from slagging. Even though both effects heat transfer, fouling happens in the convection heat transfer surface in the boiler and

Total System Efficiency with Condensing Boilers

Condensing boilers also promote heat transfer with a larger heating surface area compared to traditional, non-condensing boilers. Consequently, the ability to use alternative materials for the exhaust stack is permissible, although it is highly recommended to use a UL Listed, Category IV venting material designed for use with condensing boilers.

Determining Boiler Capacity from Heating Surface Area

I was once told that there is an equivalence between boiler capacity (steaming rate) and the heat exchange surface area. Does anyone know the relationship? I am talking about an older (1972 vintage) D-style watertube steam boiler with a design pressure of 250 psig. The nameplate states that the surface area is 3089 sq ft.
