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.
File Size: 2MB BOIL-OUT PROCEDURE STEAM BOILERS PREFACE The internal surfaces of a newly installed boiler may be contaminated with oil, grease or other protective coatings used in the manufacturing process. Such coatings must be removed since they reduce the heat transfer rate and could result in tube rupture from overheating.
Marine Boiler Safety Valve: Boilers are high pressure and temperature system used for generating steam to drive turbines. If due to any cause operation control system malfunctions and operating pressure goes above the safe limits of the material of construction it can be a catastrophic result.
Boiler operators and technicians should pay close attention to three key safety devices to protect personnel, equipment, and the facility: Safety valves. The safety valve is the most important safety device in a boiler or domestic hot-water system. It is designed to relieve internal pressure if a range of failures occur within the system.
Boiler Protection To protect the boiler against flue gas condensation and thermal shock, a mixing device should be used to control the load on the boiler. If the temperature of the boiler is below the condensation temperature or the return water temperature suddenly cools down, the mixing device can back off, allowing the boiler loop to come up
Steam Boiler Functions & Terms. Shell: Consists of one or more steel plates bent into a cylindrical form and welded together.The shell ends are closed with end plates; Grate/ Bed: it is a platform in the furnace upon which fuel is burnt.It can be a Simple Grate for combustion of solid Fuel or a Nozzle Bed for Fluidized Bed Combustion.; Furnace: it is the chamber formed by the space above the
STEAM SAFETY Steam has many applications. It can heat, do work, sterilize and move over long distances. Industrial applications where steam is often used include power, heating/cooling, tires, paper, food and beverage, wood products, pharmaceutical, refining and chemical. Steam is water that has been boiled into a vapor.
This check is an important safety issue because a deaerator can rupture from oxygen corrosion damage. The catastrophic failure of an operating deaerator is the most common source of a fatal steam explosion inside a boiler house. More info.

Aug 27, 2019· Boiler Inspection The purpose of a boiler inspection is to provide assurance of equipment integrity to minimize safety issues with operating a pressure vessel. A minimal frequency is established by law and the Insurance Company that is covering customer liability in case of any operational failures. It has a useful secondary function of acting as an early warning of potential problems and
Superheated steam is steam at a temperature higher than the saturation temperature corresponding to pressure. For example, a boiler may operate at 415 psig (pounds per square inch gauge). The corresponding saturation temperature for this pressure is 483°F, and this will be the temperature of the water in the boiler and the steam in the drum.
Additional measures for boiler safety compliance Boiler licence, manual and log • Obtain a boiler licence if the local law requires it. • Keep manufacturers’ safety manual for all equipment accessible and handy. • Keep and maintain a service log for each boiler. • Boilers should be serviced by licensed companies/individuals.
