2020-7-20 · gases and water flows inside the tubes. These boilers have a higher heating surface area and are often used to generate steam at very high pressure, temperature and output capacities like in the application of electricity generation in power plants . In the fire-tube boiler, water/steam is present in the shell side and fuel/hot flue gases
1.DZL series water and fire tube boiler use a lot of new technologies, for example, thread smoke tube, wing flue, arch-tube plate,self fixture, return water injection, etc. They can not only eliminate the disadvantages of drum deformation,tube sheet crack, water cooling wall burst but also can save energy and be more efficient.
For example addition of caster oil (which spreads on the surface of water and therefore) neutralises the surface tension reduction. (ii) The removal of foaming agent (oil) from boiler water. Traces of oils are generally introduced in boiler feed water through the lubri- cating materials used for pumps etc. Oils can be removed by the addition of

2019-7-1 · A two pass water-tube boiler is used as waste heat recovery boiler (WHRB).In this boiler we install economizer for efficiency improvement. Waste heat recovery economizer uses waste flue gases for steam production which has wide range of variations in parameters. By
Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.

Szs Gas Fired Water Tube Steam Boiler. water tube boiler,biomass boiler, gas boiler,oil boiler . 2020-8-12 · A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.
(1) Boiler corrosion: The oxygen is dissolved in water. When following feed water into the boiler, the dissolved water will react with the metal of furnace and/or tubes immediately under the high-temperature catalysis. Especially, the corrosion caused by dissolved oxygen is corrosive pitting, causing tube perforation and then rupture.
A water tube boiler comprises a furnace having a burner and a vertical flue gas stack located to one side of the furnace. A convection tube assembly is arranged in the stack for the recovery of heat from flue gases passing through the flue gas stack.
