Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.

Studies on the Failure of Economizer Tubes Involving Aci

Failure of economizer tube of a high pressure boiler of a dual purpose power/water cogeneration plant was reported [8]. The failure was observed in the form of rupturing of one tube and a corrosion activity was confined to weld or surrounding area. The front side (A) and back side Studies on the Failure of Economizer Tubes Involving

Industrial High Pressure Boiler-ZBG Boil

High-pressure boiler means a boiler operating at a steam or other vapor pressure of over 9.8MPa. It is generally used in power plant, our high pressure boilers used for power generation have capacities of 4 to 400 tonnes/hr of superheated steam with a pressure up to 13.7MPa and a temperature of about 540℃.

High Pressure Boilers | Powertherm | Manufacturer | Wate

High pressure boilers (Powertherm) are mostly water tube boilers in which water is on the tube side while flue gases flow across the tubes thereby transferring heat from flue gases to water using cross flow heat transfer.

A Review of the Common Causes of Boiler Failure in th

Failure is initiated at the surface in a high stress area. A weld undercut, corrosion pit or other defect, usually at the toe of the weld, could cause the high stress.

Failure analysis of the wall tubes of a water-tube boile

Since these machines operate at high temperature, at high pressure, and in abrasive environments, boiler tubes often suffer from a variety of failure mechanisms, such as overheating , , pitting corrosion , , creep , erosion , thermal fatigue , corrosion fatigue , and stress corrosion cracking (SCC) .

Pressure vessel - Wikiped

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Pressure vessels can be dangerous, and fatal accidents have occurred in the history of their development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering
