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.

In-Situ Zirconia Oxygen Analyzer (HART Communication) <ZKMA, ZKMB, ZFK8> In-situ oxygen analysis requires no gas sampling device Ideal for combustion control in industrial boilers and furnaces
Common Chemicals Used in Boiler Water Treatment Boiler water treatment is the conditioning and treatment of boiler feed water with the purpose of meeting three objectives. In order for boiler water treatment to be maintained, there must be a continuous heat exchange, protection for high-quality steam, and corrosion protection.
Our oxygen sensors cover a measurement range from 1 ppb up to 45 ppm dissolved oxygen, and even measure ultra-low oxygen traces down to 0.5 ppmv O 2 in gases. Compared to other methods, optical O 2 sensors do not consume the analyte during measurements, which is an important advantage when measuring in low oxygen environments. All of our oxygen sensors come pre-calibrated, and with a …
A significant portion of the NOx from stationary sources can be attributed to residential, commercial, and industrial sources, including industrial boilers. In industrial boilers, NOx is primarily formed in two ways; thermal NOx and fuel NOx: Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the
An electronic sensor is inserted into the boiler flue, near the boiler, ahead of any dampers or other sources of air leakage into the boiler or flue. The sensor is connected to a control panel that measures oxygen and sends a signal to a control damper on the burner air supply. From the Hays Cleveland OXY-MIZER™ data sheet:
In-Situ Zirconia Oxygen Sensor has been designed to measure excess oxygen in a wide variety of combustion processes. It is an outstanding unit for monitoring oxygen concentrations in combustion gas of large or small boilers, industrial furnaces and combus tion processes or for the control of low percent oxygen combustion.
The new oxygen sensor’s greatest initial potential is with industrial boilers, which have a market size of approximately 50,000 units.The total number of new boilers of all sizes registered annually by the National Board of Boiler and Pressure Vessel Inspectors
Combustion control in domestic boilers using an oxygen sensor G. Conte – M. Cesaretti – D. Scaradozzi Dipartimento di Ingegneria Informatica, Gestionale e dell’Automazione “M. Panti”
The oxygen sensor is inserted into the boiler flue to monitor the oxygen level, enabling complete control over the boilers oxygen to fuel ratio. Here is an example of a combustion process using SST’s zirconium dioxide oxygen analyser , the OXY-Flex as a feedback signal into the controller system.
There are numerous technologies capable of measuring oxygen with each providing certain advantages and disadvantages. Understanding how a sensor works is the first step in selecting what’s best for your particular application. In general there are three sensor technologies that make up most of the industrial oxygen transmitter / analyzer market.
