corrosion and erosion due to lack of heat transfer
A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler. The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler. They serve a two fold purpose here in that they capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler. And they also help keep the refractory cool (relatively speaking) This prevents spalling of the refractory.
Boiler can be classified as below
boilers which are used in ships called as marine boliers.
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.

The term "once-through boiler" refers to a special type of water-tube boiler composed oftubes, in which water is input at the bottom, and steam is produced from the top.
Spalling: To break into fragments or small pieces."Spalling can be described as the breaking of layers or pieces of concrete from the surface of a structural element when it is exposed to the high and rapidly rising temperatures"
Common causes of foundation spalling in buildings include water infiltration, freeze-thaw cycles, poor construction practices, and chemical reactions. Solutions for foundation spalling may include proper drainage systems, waterproofing, repairing cracks, using quality materials, and regular maintenance.

Hi. No, these are not the same thing. A Combi-boiler can be a type of condensing boiler that does not need a tank and just heats the water on demand. A combi boiler can be of a condenisng type - in other words there are combi boilers that are condensing boilers. However, there are many types of condensing boiler that do have a holding tank, so not all condensing boilers are combi-boilers. By the way, if you are looking into a combi boiler, make sure that your installer has factored in your likely hot water usage and that this type of system will supply you what you need even at peak times.
The DOE heating capacity MBH oil fired heating boiler refers to the heating capacity of the boiler. The DOE is one of the best boilers in the market.
