the chart on page 3. As water is heated inside a boiler the lime scale forms deposits on the inner walls of the copper tubes and waterways. This accumulation of lime reduces water flow through a boiler; a critical aspect of a boiler's operation and performance. The following reasons for removing this lime scale build upGet Price
Difference Between Fire Tube Boiler and Water Tube Boiler . Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.

Answer (1 of 4): Philip Miller's q: where does come the first water that feeds the boiler's tube in a thermal power electric? A: First of all you have to consider that boiler's tubes are not clean enough for allowing the steam to touch turbine blades immediately. Therefore the first steam is comGet Price
The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).The make-up water is usually natural water either in its raw state, or treated by some process before use.Get Price

ULTRAMARINESM HP BWT Program • Drew Marine pioneered the "modified phosphate-pH treatment" – Utilizes disodium orthophosphate and caustic so that no "free caustic" is generated in the boiler water – Sodium to phosphate ratio is approximately 2.75:1 and provides margin of safety for good control of the program – Went into effect in the marine industry in the 1960's …Get Price
Aug 19, 2019 · Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor. The water may need filtering to operate most effectively.Get Price
On 13th October 1936, the water-tube boiler W1 made its last journey: from Darlington Works to Doncaster Works to be rebuilt with a conventional fire-tube boiler. Out of the 1,888 days since it was built, No. 10000 spent 1,105 days in Darlington Works.Get Price

Feb 19, 2015 · The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. Here are a few key differences between the twoGet Price
Oil and gas water tube boiler vs fire tube boiler. The ZBG wns series oil and gas boilers are fire tube boilers, and the szs series oil and gas boilers are water tube boilers. There are differences in the structure and performance between the two boilers. KefidGet Price
Feb 24, 2012 · As the water and steam both are in same vessel a fire tube boiler cannot produce steam at very high pressure..

Mar 16, 2017 · Water tube boilers have better efficiency ratings and generally drive lower fuel costs. They do cost more up front, however, and cleaning the unit can be difficult because of its design. Fire tube boilers, on the other hand, are relatively less expensive, smaller in size and easier to clean though they have pressure limitations.Get Price
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. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica Get Price
The heat from the hot gases transfers through the walls of the tubes and heats the water. In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes, heating the water and then out the boiler vent.Get Price
Deposits do not form on boiler tube walls at a uniform rate over time. Immediately after a chemical cleaning, the boiler tubes create a protective film of magnetite that limits further corrosion of the base metal. This quickly adds 3 to 5 or so grams/ft.2 of deposits to the boiler. Over time, new deposits collect on top of this protective layer.Get Price
pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate. As the temperature difference between two working media is small, economizer needs a very large heat exchange surface.Get Price
