material used in water tube boiler

Condensing steam material used in water tube boiler is the use of high-efficiency flue gas condensing waste heat recovery device to absorb the sensible heat in the tail of the boiler and latent heat released by steam condensation in order to improve the thermal efficiency of the boiler.

If you know the rated working pressure of the hot water material used in water tube boiler, how to determine the setting pressure range of the safety valve? If a hot water boiler knows its rated working pressure, then it is possible to determine the setting pressure range of the safety valve, which is 1.1 times the working pressure on the lower limit of the pressure value, but not less than the working pressure plus 0.07MPa. In the upper limit of the pressure range, it is 1.2 times the working pressure, but not less than the working pressure plus 0.1 MPA.

Fire tube hot water material used in water tube boiler operate

Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessel of the boiler. As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them. As a result steam is generated in the water and naturally comes up and is stored upon the water in the same vessel of fire tube boiler. This steam is then taken out from the steam outlet for utilizing for required purpose. The water is fed into the boiler through the feed water inlet.

Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water material used in water tube boiler of 2.1MW.

BRIEF HISTORY OF WATER-TUBE BOILERS [1] -

2007-9-18 · The first successful user of water-tube boilers, however, was James Rumsey, an American inventor, celebrated for his early experiments in steam navigation, and it is he who may be truly classed as the originator of the water-tube boiler. In 1788 he patented, in England, several forms of boilers, some of which were of the water-tube type.
