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.

Summary: The following article is a part of the National Board Technical Series. This article was originally published in the October 1989 National Board BULLETIN. (3 printed pages)
While any lagging project requires planning and preparation, when working on large air-pollution equipment projects or boiler conversions, each step must be considered in order to meet construction schedules. Following are some key areas of consideration. Preliminary Preparations
Apr 17, 2017· How to Start a Boiler. Home boilers heat fluid, in most cases water, to provide warmth during the cold months. During warm months, boilers are turned off to save fuel and electricity. Prep your boiler for startup when cold weather comes by
File Size: 1MB Hartford Steam Boiler Heating Boiler Start-up Checklist − The safety and safety relief valve should be tested for freedom of operation. This is of primary importance. The boiler must not be fired if the safety and safety relief valves are inoperative or otherwise defective. These valves should be tested once a quarter while in service.
The actual project area for crane placement was very tight. Nooter Rigging Engineer Jeff Rapert had to take into consideration the 90-foot length of the new waste heat boiler, its eight-foot diameter and the weight — 225 tons. A major challenge included the unit having to reside vertically in the middle of a support structure.
the Boiler Operator. This is a pressure control which senses the steam pressure and turns the boiler on and off accordingly. This control must be operationally tested. Adjust the pressure setting on the control to a pressure less than the boiler pressure (as shown on …
Boiler - Fundamentals Steam production and steam uses Steam purity and steam quality Types of boilers Basic boiler principles Basic boiler calculations. Steam Production and Therefore the boiler water will contain more solids than the feedwater This Concentrating effect …
