Read Morepassivate, or protect the metal surfaces in the boiler, and hydrazine is used as a passivating agent as well as an oxygen scavenger. Hydrazine decomposes in the boiler water at 400-600 F (250-1500 psia): 3N 2H 4 = 4NH 3 + N 2 (3-23) Feed rates of about 5
Read Moreheating boilers' efficiency is no less 85% due to the efficient design of the boiler and furnace; solid fuel boilers have a large volume of the combustion chamber to reduce the frequency of loading in manual mode; high speed of flue gases and heat agent of the heating boilers;
Read MoreA steam boiler has an interface of steam and water in the steam drum, which is where the water is finally evaporating due to the heat input, usually oil-fired burners. When a water tube fails due to any of a variety of reasons, it causes the water in the boiler to expand out of the opening into the furnace area that is only a few psi above atmospheric pressure.
Read More20/11/2009 · There are many reasons for furnace seal breakage. In a coal fired boiler, a large clinker falling into the bottom hopper can lead to a furnace seal breakage. The large clinker fall results in an appreciable volume of steam production from the water trough of the bottom hopper which pushes out the water from the seal area.

Read MoreAsh from the boiler is collected in a hopper directly below the furnace, whence it is removed by high pressure water jets and discharged, via sluiceways, into ash crushers. The crushed ash falls into ash tanks, and is then projected by water-jet pumps supplied by HP sluice pumps through discharge pipelines to ash pits, where it is allowed to settle.
Read MoreWater could be used as the sealing medium in the trough, but it has some drawbacks. At the furnace temperature of 1500 -1600 F., much steam would be generated, which would permeate throughout the boiler complex. Also, the large water loss would require
Read MoreCleaning medium – the substance used to clean soot or ash buildup on boiler tubes. The cleaning medium may be saturated steam, superheated steam, compressed air, water or a combination of these. Saturated steam is the most widely used medium because: Boiler-generated steam avoids the cost and maintenance of a compressor.
