WNS series horizontal internal combustion boiler 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.
1. 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.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. 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.
4. 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.
Flotation method for non-ferrous metal variable ores . Dec 30, 1997· The present invention concerns a method of separating variable ores containing copper, lead, zinc and the like as the refining material for non-ferrous metals and gangue minerals such as pyrite, quartz, feld spar and the like from dug out ores and, particularly, it relates to a flotation method.
The processes in non-ferrous metallurgy are often very exothermic. For example, in the smelting of sulfur-containing primary raw materials or in the thermal processing of highly organic residues, hot process gases are produced. The worst solution would be simply to destroy the energy contained in it by a simple exhaust gas cooling.
NON-FERROUS METALS PLANT was founded in 1950. Three years later were put into operation the repair-mechanical, instrumental, metal-boiler, cast iron, electrical power facilities of the work. December 18, 1954 the first brass bar was casted in induction furnace. January 15, 1955 on 1000-ton hydraulic press was pressed first brass rods.
Handbook of Non-Ferrous Metal Powders: Technologies and Applications, Second Edition, provides information on the manufacture and use of powders of non-ferrous metals that has taken place for many years in the area previously known as Soviet Russia.It presents the huge amount of knowledge and experience that has built up over the last fifty years.
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.Metallurgy encompasses both the science and the technology of metals. That is, the way in which science is applied to the production of metals, and the engineering of metal components used
Melt Cover for Non-Ferrous Metallurgy . Carbonaceous materials are typically used as melt covers over pure copper, brass and bronze or other copper alloys, to prevent oxidation of the melt and to deter formation of oxide slag. While various materials can be used, high purity materials provide a high level of protection with a minimum amount of
