Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

sulfuric acid waste heat boiler plants - LinkedIn SlideSha

Jul 13, 2015· Email address:zgboiler123@gmail.com Sulfuric acid waste heat boiler plants In the manufacture of sulfuric acid by the contact process,raw sulfur is burned in a combustor with air. The resulting gases containing SO2,N2,O2 at about 1800-1900 F and at a pressure of about 2 psig enter a waste heat boiler and the gas is cooled to about 750-800 F.The

1,650 TPD Sulfuric Acid Plant for - Used Process Plan

Used 1,650 TPD Sulfuric Acid Plant built in 1966. Sulfur is first melted in the sulfur day tank. The molten sulfur is pumped to a buffer pit, and then to sulfur burner. A waste heat boiler (#1) recovers the heat from the sulfur burner to generate sulfur dioxide. The SO2 proceeds to …

Waste Heat Boilers | Optimus | Chanute Manufacturi

For high-capacity sulfuric acid plants, in particular, Optimus offers a system with two boilers operating in parallel with a common steam drum to accomodate very high heat duty and steam production requirements. Optimus unfired waste heat boilers recover valuable BTU’s from hot process gas.

Hydrogen formation in sulfuric acid plants a

Irrespective of a leak occurring in an economizer, waste heat boiler or acid cooler, ultimately the water will enter the absorption tower, eventually resulting in circumstances where the acid strength can’t be controlled anymore, hence the sub-system of the intermediate absorption tower is the area of the highest potential for hydrogen formation.

Rapid waste heat boiler retubing at IPL Mount I

Feb 01, 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.

Waste Heat Boiler In Production Of Sulfuric Acid - Stude

May 21, 2012· Waste Heat Boiler In Production Of Sulfuric Acid - posted in Student: Hi, I'm asked to design a waste heat boiler which produces steam uses the heat of reaction of sulfur burning in a sulfuric acid plant of 50ton/day for my final year project. I need help from you guys.. Any link/idea is admirable. Advance thanks to you guys.. > this WHB reduces the temp.of So2 gas to around 250c from

Waste Heat Boiler - an overview | ScienceDirect Topi

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
