water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Steam Piping Best Practices | CleanBoiler.org

This steam trap is therefore acting mostly as a "steam cooler" wasting steam from the Steam Main. Note the nice insulation job however; this is probably keeping the problem from being much worse. Condensate should always be drained from the BOTTOM of the steam line in low sections of pipe and at changes in direction, such as a 90 Degree turn.

How to Calculate Boiler Steam Flows | Hunker

Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.

Steam Boilers – Accuracy Matters - WCP Online

Apr 17, 2014 · Boiler feedwater (FW) for industrial boilers is a combination of pretreatment make-up and condensate return (CR), (FW = CR+MU). In boilers, not all water escapes as steam. In many applications, only part of the steam exits through the process. This unused steam returns to the boiler as condensate —referred to as condensate return.

Barry Dooley, in Heat Recovery Steam Generator Technology, 2017. 15.2.1.2 All-volatile treatment (oxidizing) [1]. All-volatile treatment (oxidizing), or AVT(O), has emerged since the 1990s as the much preferred treatment for feedwater systems that only contain all-ferrous materials (copper alloys can be present in the condenser). In these cases, a reducing agent should not be used during any

Is Your Steam Quality Worse Than You Think? | TLV - A

Steam often still contains moisture because of two reasons: Virtually all boilers produce steam with a certain amount of condensate in it unless additional superheating is performed. This is in part because steam dryness can decrease due to sudden fluctuations in load, causing some of the boiler water to get entrained within the flow of steam.

A method and apparatus effectively bypasses flue gas through or around selected boiler convection heat transfer tube banks within a new or existing boiler flue. Heat transfer tubes are removed, or omitted in the design of a new boiler flue, forming one or more voids at one or more locations within the tube banks. A bypass flue or conduit is formed within each void, for example using steel
