valves for steam boiler of sulphuric acid plant - Bing 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.
2019-10-19 · Sulfuric Acid Recovery Plant. Back to top. High Concentration of Sulfuric Acid. Because of the acidity of the vapors from the high concentrated boiling sulphuric acid, it is necessary to scrub the vapors. On their way out through the horizontal boiler the acid flows through baffles that separate the horizontal boiler body into
The new Sulphuric Acid Valve joins the growing range of AVT products, already recognised for "class busting" performance in Hydrochloric Acid and other corrosive media. Advanced Valve Technologies (AVT) is the world leader in applying reinforced composite technologies to valves and related products.

Valve & Automation provide solutions to this tough industry where most valves do not last more than a few weeks on abrasive slurries. Machinery and plant must be capable of dealing with media with a high amount of solids, abrasive material, corrosive chemicals as well as high velocities.
In addition to our engineering capabilities, we maintain a large resource of highly skilled bricklayers, craftsmen and field laborers experienced in acid plant and other severe service lining applications. THORPE has been involved in acid plant linings since 1954. We began with maintenance work and secured our first new acid plant project in 1960.
Sulphuric Acid production based on Sulphur combustion is an exothermic reaction generating a considerable amount of heat which can be recovered of heat which can be recovered as high-pressure steam which can be converted into electricity.
Velan supplies the chemicals industry with valves for polymers such as polyethylene, k-resins, vinyl chloride, monomer, catalysts, crystals, and many other applications. Valves in sophisticated materials such as titanium, monel, and hastelloy are supplied for corrosive acids, aromatic anhydride, sulphuric acid, ethylene dichloride, and others.

Some examples of possible revamps for sulphuric acid plants For the purpose of this paper the term sulphuric acid plants shall include the wet gas cleaning section of metallurgical acid plants as this plant area is of utmost importance for the downstream drying, converter and absorption section and has direct impact on plant performance
The steam generated by the boiler is used for melting sulphur and driving the main air blower. The steam can also be used for power generation. Features of waste heat recovery boiler on sulphuric acid plant. Both fire-tube and water-tube constructions possible; fire-tube boilers can be offered in both flexible and fixed tube-sheet design
A primary objective in designing a boiler is to provide for the greatest possible efficiency in absorption of heat. Other objectives are production of pure steam and safe, reliable operation. Boilers in acid plants are waste heat boilers cooling gases from sulphur furnaces, regeneration furnaces and between catalyst beds. Types of Boilers
CEAMAG is dealing in Sulphuric Acid projects through the partnership with Daniel LEFORT, one of the most experienced Experts having numerous references in design, full engineering, procurement of key equipment and catalysts, and eventually managed the Commissioning of recent plants at …
1/2/2017· In the case of the IPL Mount Isa sulphuric acid plant, 2014 presented some very serious challenges associated with maintaining the site’s 16 year old No. 1 Waste Heat Boiler (WHB1). WHB1 is a horizontal tubesheet boiler with 859 tubes, 70mm diameter x 9000mm long. The boiler shell is 3410mm ID and 45mm thick. Process gas from the sulphur
1/5/2012· Solubility in weak sulphuric acid is typical for most spent acid from refinery and nitration processes. If the dust and ash solids are not soluble in weak acid, electrostatic mist precipitators are required. The SO2 bearing gas is then dried by contact with 93 to 96% H2SO4 in a packed bed acid tower or drying tower.
