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.
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. My injection boilers were open systems utilizing water column to build pressure so no ASME rating or …
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%.

May 05, 2015· Boiler Chemistry Control and Treatment of Feed Water By: Swapan Basu , Posted on: May 5, 2015 It is essential to make sure the efficient boiler start up and commissioning with the help developing suitable means and workable approach to meet the various chemistry limits set for boiler especially for once through supercritical boilers where
For safe and efficient operation, the quality of feedwater, steam, and condensate in boiler plants must be controlled and maintained in the most favorable conditions. For reclamation drain from makeup water desalination systems and condensate desalination systems, and equipment washing wastewater in thermal power stations, as well as acidic or alkaline wastewater from desalinated water production …
User rating: 5/5 So let’s cut to the chase. Please don’t let your customers inject chemicals in any form into the boiler feed receiver. At the very least they’ll create the following issues: 1. Solid or powdered chemicals injected into the boiler feed receiver won’t fully dissolve. There’s just not enough mixing.
chemical feed pump is wired to the boiler water feed pump. Every time the boiler calls for feedwater, small amounts of a concentrated mixture of chemical are added while the feedwater pump runs. If the boiler water feed pump does not run, chemical is not added. This system will provide constant chemical treatment levels 24 hours per day.
First, determine the pressure rating required for injection the chemical into the system. Also, if you are injecting the product into the feed water line or feed water tank, make sure to use an injection quill to disperse the chemical near the center of the line or tank.
File Size: 63KB Boiler Water Treatment Chemical Guidelines—Part Il continued Because of the associated corrosion problems, chelants are not the preferred treatment choice. However, if the system dictates the use of chelating agents, it can feed under "starvation" conditions, i.e., no free residual in the boiler. Based on the trace level of hardness in the boiler
