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.

How to "inject" steam? - Equipment - ADI Foru

User rating: 5/5 Jun 14, 2019· These stills are still in operation. One is at the Bell of Dayton Distillery in Dayton OH. The injection boiler that I built for them has 72 square ft of internal heat exchange surface area.

Hot Water Boiler Chemical Guide - ChemWor

Price: $0.99 Implementing the nitrite boiler chemical is very simple. Simply charge the system with 800 to 1,500 ppm of sodium nitrite. Blends of sodium nitrite with a “P Indicator” chemical make it even easier. Simply add the product until the boiler water turns light pink. A nitrite test kit or strips will still work with a “P Indicator” boiler chemical.

Examine the results shown on the examples. If the dissolved oxygen concentration varies from 0.01 ppm to 1.0 ppm in the feedwater, to maintain the 30 ppm boiler water residual, the daily dosage demand increases by almost 500% and the reaction demand increases from 3.9% of the dosage to 80%.
