2015-9-14 · In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers.
Operation of Fire Tube Boiler - INDIA BEST BOILERS
A firetube boiler is a type of boiler in which hot gases pass from a fire through one or (many) moretubes running through a sealed container of water.The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.

2019-5-24 · Feed Water Treatment to Avoid Corrosion - Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems; Maximum Flow Velocities in Water Systems - Water velocities in pipes and tubes should not exceed certain limits; Steam Boiler Rating and Feed Water Temperature - Boiler output and feed water
Our oil/gas fired boilers can be divided into DHS series angle tube boiler,SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above.
If hydrazine (N 2 H 4) is not used, sodium sulphate (Na 2 SO 4) can be used instead, and the excess should be 30 60 ppm.. In cases where other kinds of oxygen binding agents are used, it is recommended that an excess of oxygen binding agents can be measured and indicates that no oxygen has been dissolved in the boiler water.
Effect of Water Quality on the Performance of Boiler in
Based on the results obtained it could be concluded that the performance of the boiler is low and it is not working in conformity with the design. The boiler failures observed were partly due to the poor boiler feed water quality, which, was traced to very deplorable condition of the water feed into the boiler. References
