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.

What is afbc boiler?
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.
How boilers are classified?
A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and process application. A high pressure steam boiler can be named as Power Boiler, in which design and construction rule following to rules of ASME Boiler and Pressure Vessel Code Section I - Power Boiler.
What is the difference between a condensing central heating boiler and a combination boiler?
A combination boiler can use one of two different fuels to heat the water. Common combinations include natural gas/propane and oil, or wood and oil combinations. A condensing boiler uses a secondary heat exchanger to condense water vapour (steam) in the products of combustion down to water. Here's what that means: When any hydrocarbon (gas, propane, oil, even wood) burns, it gives off at least two "products of combustion. The carbon combines with oxygen to create CO2, carbon dioxide. The hydrogen combines with oxygen to create water vapour, or steam. (If combustion is "incomplete," there will be other trace products as well.) It's the water vapour or steam we're concerned with here. To boil 1 pound of water requires 960 BTUs of heat. Conversely, if you condense steam down into 1 pound of water, you will recover 960 BTUs. The fuel is burned in the "primary heat exchanger," where of course it releases a tremendous amount of heat into the water we're warming up. Then the "products of combustion" are drawn by a fan into the "secondary heat exchanger." When the water vapour or steam component of the products of combustion hits the relatively cool walls of this second heat exchanger, they condense down into liquid water. As they do, they release heat into the boiler water through the walls of the secondary exchanger. The liquid water then goes down a drain. Obviously, the boiler water has to be cooler than the steam component of the products of combustion in order for the heat to travel into it. So we make sure that this water is what's coming back to the boiler from the heating system. Again, for this method to work well, it's best applied in a "radiant in-floor" type heating system, where we don't heat the boiler water up to as high a temperature in the first place. --The HVAC Veteran
Is a water heater install considered a capital improvement?
Never in a million years as it does NOT add value to the property and the typical life span of a tank type heater is 12- 15 years. Now if you had installed a new boiler which increases the value and the boiler has a tank next to it that makes hot water then your accountant can do some creative accounting
What is the meaning of once through 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.
What is a simple vertical boiler?
A simple vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation.
How many type of turbine cold startup?

Is a condensing boiler the same as a combination boiler?
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.

What is drum boiler?
A drumless boiler is obviously a boiler without a drum. The steam is fed into a header, then into a turbine for making electricity. Quality control of the water used is of extreme importance. Since there is no water level in a drum to maintain, feedwater must be constant with no interruption of any kind. With a drum type, water feed can be interrupted for a very short time. Not so with a drumless type.

Can you use rainwater in your little yell steam machine?
you could,but u would have to clean it more often beause with any boiler type system ,be it a house boiler , an industrial boiler or your little steam machine when water is boiled out it is pure with no impurities.the impurities stay behind because they are heavier which leaves u with build up that will cake to the walls of ur machine and eventuelly lead to clogging or poor efficiency. so u could but its not recommended

What type boilers did the first USS Fulton have?
As far as I can find out the First USS fulton,(Demologos) had a copper boiler located in the port side hull. The boiler was 22' long by 14' dia.
What are combi boilers?
Combi boilers are designed to accomplish both space and water heating with a single appliance. Like a tankless water heater, a combi boiler provides hot water on demand. It can also seamlessly switch between water heating and space heating to provide the best possible experience.
