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: 438KB A properly prepared energy balance sheet analysis of a system or an entire plant is an excellent way to present your energy survey results to management. Terms such as combustion efficiency, boiler efficiency, and plant efficiency should be included in the energy survey and the losses, but these terms can be confusing.
STEP 1: COMPLETE A JOB SURVEY FORM Certain key information is required for each boiler replacement job in order to calculate the heat loss, select the proper boiler and determine the selling price. Figure 1 is a Job Survey Form (part of a Weil-McLain Boiler Replacement Worksheet) to aid in recording the required information.
File Size: 707KB Jan 30, 2013· A complete boiler survey allows us to check out if any build-up of deposits has taken place, and deformations or wastage of plate work, piping or any of the various parts, which may compromise the sale working order of the unit. The survey should include research as to cause of any anomalies found and also their correction.
Nov 03, 2014· BOILER SURVEY Introduction Boilers are inspected to maintain the regulatory requirement. Regular internal and external examination during such survey constitutes the preventive maintenance schedule the boiler goes through to have a safe working condition. Interval: Boilers require to be surveyed at 2-year intervals until they are 8 years old, thereafter they become due for survey …
Steam Distribution System Drip Leg(s) Form Our steam system audit starts at the generation point, the boiler(s). We perform combustion efficiency testing, analyze skin radiation and blow down losses, then calculate the boiler’s overall efficiency.
The Boiler and Refractory Infrared Survey distinctly locates the radiant piping to prevent cutting or drilling through the pipes during repair and remodeling projects. Boiler and Refractory Infrared Surveys are also used to locate leaks and other malfunctions in buried steam or hot water lines.
Apr 18, 2019· Boiler Survey on ship is an important task to be carried as per the classification society requirements. A lot of planning and work force utilization is needed. Let’s peek in to as how to plan this and tips to do this efficiently. Requirement of Boiler Survey On Ship. The reason is simple.
boiler riser INSTALLATION SURVEY – STEAM 2. C. Gravity Return Systems 1. Figure 1 shows how a gravity system works. The 28 inch dimension for the back-up of water in the returns allows for a system steam pressure loss of ½ psig. Make sure to add additional height allowance if the system pressure
In this series let us discuss about the inspection or survey carried out in the marine boiler at regular interval, along with the scope of inspection. The inspection on the marine boiler parts are carried out starting from the Furnace, Economizer, Boiler Mountings and finally on boiler superheaters.
Preparation for survey: Shut down the boiler and gradually cold down. All steam valves tight shut; Carry out bottom blow down properly; When the boiler pressure in near to ATM pressure , open the boiler vent valve , sight glass drain cock , salinometer cock to prevent the …
