high presser boiler hematite & magnetite lear is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

Magnetite forrnation by the reduction of hematite with iron under hydrothermal conditions Ar-lN Mnrrnnws Department of Geology, Hebrew Uniuersity Jerusalem, Israel Abstract The formation of magnetite by the reduction of hematite with iron in the presence of aqueous solution at 350-570"C, 1-2 kbar pressure, takes place by two reactions: (l) the
Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH.

how to convert magnetite to hematite on boiler tubes. 2016-06-14 Published by: Cindy 0 . As a 70 years experience of boiler manufacturer, ZG provide various type of energy-saving boilers, like gas fired boiler,oil fired boiler, biomass fired boiler, CFB boiler, industrial autoclave, as well as chain grate boiler for customers to chose.
Pre-boiler and Boiler Corrosion Control | GE Water Learn how pre-boiler and boiler corrosion are some of the main causes of reduced … sulfite decomposes in high-pressure boilers to form … hematite: magnetite: magnetite drive – angelfire.com The so-called “Magnetite Drive” General description. … hematite and magnetite, depending on the operational pressure of the boiler.
Measuring Internal Oxide Scale in Boiler Tubes Background: The very high temperatures found inside steam boilers (in excess of 1500 °F (800 °C) can cause the formation of a specific type of hard, brittle iron oxide called magnetite on the inside and outside surfaces of steel boiler tubing.
Another important effect of pH modification is the impact on magnetite stability. In high-pressure condensates or boiler feed water section, even at alkaline pH, working out of optimal pH range will affect the magnetite stability, resulting in higher iron concentration in boiler feed water.
