Design and sizing of Natural Gas line to burner of steam boiler

The boilers are actually rated in steam output such as 10 ton of steam per hour. This is equivilent to about 6,500,000 kcal/hr. Now often I notice that such size boilers are equipped with a 10,000,000 kcal/hr burner. Why is this and should the gas lines be designed according to the boiler rating or the burner rating? Thanks again.

Boiler Systems: Strive for steam quality - Plant Services

Aug 22, 2012 · The primary mechanism for impurities in steam is water droplets getting carried over with the steam from the boiler. For scrubbing steam coming out of a boiler, there are a number of separation/mechanical scrubbing strategies to achieve 99.0% to 99.95% steam purity, explains Vasudevan. Boiler system design is crucial

The Interactions Between Steam Piping and Boiler Outlet

Interactions between steam piping and boiler outlet headers are not always fully considered in the original design or retrofit of these fossil plant components. This is surprising since they form an inte- gral path for steam flow from the boiler to the turbine, and the components are seldom separated or iso- lated by a full anchor on the piping.

Nov 19, 2013 · Water-tube boilers may vary in design; however, their basic principles of operation are the same. This type of boiler consists of two drums, a series of water tubes, a feedwater inlet line, and a combustion gas outlet stack. These tubes are connected to a steam drum and a mud drum. The water is heated and steam is produced in the upper drum.

Jun 24, 2014 · One outlet may have been enough in the old days because the boiler was much larger, had wider sections and a more generous steam chest. A boiler of the same rating nowadays, however, may need two or three outlets to dry the steam and balance the water line.

This has to be right to get dry steam. The early boiler manufacturers used large steam chests and large openings to produce dry steam. Modern boiler manufacturers use the piping around the boiler to dry out the steam. Undersized pipes create higher outlet velocities, which can carry water out of the boiler as wet steam.
