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.
The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water

Flue gas stratification in the boiler exit duct may require an off-center position for the oxygen probe or the use of multiple probes. To support an optimal combustion control strategy an in situ oxygen analyzer — a probe inserted directly into the flue gas duct without the need for a sampling system — should be used.
System gas boilers; Heat only gas boilers . Combination (combi) boilers. This is the most popular type of units for domestic hot water production and gas central heating. It is easily installed and is regarded to be the most highly reliable appliance. The unit supplies water …

Location: Newman Lane, GU34 2QJ Alton Hampshire, United Kingdom The two designations in the table are automatic control and positioning control. Positioning control is generally not equipped with continuous flue gas oxygen measurement. The more efficient control is automatic control.Automatic control (or continuous automatic control) continually monitors oxygen content and combustion air flow is trimmed to maintain required oxygen limits, sometimes
Measuring the flue gas parameters of the burner (CO, O 2, and temperature, etc.). The flue gas measurement for a heating system helps to establish the pollutants released with the flue gas (e.g. carbon monoxide CO or carbon dioxide CO 2) and the heating energy lost with the warm flue gas.In some countries, flue gas measurement is a legal requirement.
Control of Boiler Operation using PLC – SCADA K. Gowri Shankar Abstract––This paper outlines the various stages of operation involved in the conversion of a manually operated boiler towards a fully automated boiler. Over the years the demand for high quality, greater efficiency and automated machines has increased in this globalised world.

File Size: 296KB Automatic Water Feed Christopher: We also have a Weil-McLain steam boiler for 1 pipe steam. When we had it installed, the technician did include an automatic water feed. It's a good feature to have. During the middle of the winter, I drain out the dirty water about every 1-2 weeks and then add water with the automatic water feed.
Location: Newman Lane, GU34 2QJ Alton Hampshire, United Kingdom Overview Brief Introduction: SZS series oil and gas fired boiler is a packaged water tube boiler with double drums and D-type layout. It has lots of advantages such as sufficient burning, no pollution in the emission, convenient operation, easy installation etc.
