Boiler - an overview | ScienceDirect Topics

A two-drum boiler bank was very typical in early boilers and is still used in smaller, low-pressure boilers. In small biomass BFB boilers one can often find a boiler bank (i.e., an evaporative heat transfer surface). To keep the steamwater mixture flowing, the tubes are often inclined 515 degrees from horizontal.

Water Levels in Steam Boilers | Spirax Sarco

In horizontal shell boilers, the water level rises with increasing load (due to the presence of more steam being below the water level in the boiler). As it does so, the water surface area (steam release area) will decrease because, as the water level is above the centre line of the boiler, the sides of the containing shell converge.

Chapter 14 - Boiler System Failures | SUEZ

An embrittlement detector may be used to determine whether or not a boiler water has embrittling tendencies. The device, illustrated in Figure 14-4, was developed by the United States Bureau of Mines. If boiler water possesses embrittling characteristics, steps must be taken to protect the boiler from embrittlement-related failure.

Boiler Types and Classifications - Wiki - odesie by Tech Transfer

A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater. Because of its similarities in many ways to a steam boiler, the term ''hot water boiler'' is used. Hotwater boilers that have temperatures above 250° Fahrenheit or pressures higher than 160 psig are called ''high temperature hot water boilers''.

Back to Basics: Venting for Gas-Fired Boilers | 2003-06-04

Jun 04, 2003 · A Category I vent system works by allowing heated flue products to rise vertically, so the vent pipe must rise vertically from the boiler vent connection as soon as possible. You should also limit the length of the horizontal flue pipe. All horizontal runs of vent pipe must rise 1/4 inch per foot of run to maintain proper draft in the vent. Any

Why do boilers in thermal power plants are vertical but not

Apr 23, 2018 · Boiler aka Tubes expands on heating and thus vertical Boilers give easier option/space for vertical expansion. Whereas it would require more space and rather more difficult in case of horizontal boilers. Also it helps in natural re-circulation in case of small sub-critical boilers. Steam Locomotives are no more used, are outdated and so no comparison.

Overall Efficiency

Efficiency within a model group will tend to vary by the size (capacity) of the unit. Some products, like furnaces, may also be affected by installation orientation (horizontal, upflow, or downflow) or even by the nozzle used in installation, as is the case with boilers and oil furnaces.

Why does a boiler drum always horizontal and not vertical

Feb 07, 2019 · Boiler shells are designed to function in either direction. The fact is, that a horizontal tube boiler tends to be slower to react and more efficient depending on the number of passes the gasses make through the shell. A vertical tube boiler tends to respond fairly quickly while being fairly inefficient. It all depends on application.

Boiler-Venting Considerations - Heating Help

When you remove the boiler venting and leave the existing water heater or pool heater in the old chimney, it is referred to as an orphan. This is where the Seven Times Rule comes into the play, which is: The flow area of the largest common vent or stack shall not exceed seven times the area of the smallest draft hood outlet.
