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.
Cited by: 11 The main flaw in measuring fuel-to-steam efficiency is that it’s only relevant when a boiler is working at maximum capacity. Obviously, most boilers aren’t running at maximum capacity 24/7, and so the fuel-to-steam measurement doesn’t take into account the specific service operations.
The ASME Boiler and Pressure Vessel Code Section I establishes the requirements for steam drum water level measurement in fired steam drums. The primary focus of these requirements is safe boiler operation. Maintenance, performance, and other specific application issues are not addressed.
Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas. The typical package boiler is a water tube boiler or flue and smoke tube boiler with a capacity of 5 to 20 t/h (average steam generation capacity). The most widely used fuels are heavy oil, light oil, and gas.
The actual differences between the measurements vary with fuel type, ambient moisture content and boiler heat rates, but generally for a coal fuel a difference between 0.2 and 0.7% is realistic. The graph below (Fig 2.) shows actual differences between the wet …
The details of how the differences in terms of the fuel-air mixture can be best set vary according to the boiler manufacturer, type of fuel and control plan. Some burners control the quantity of air which is taken into the boiler, others the quantity of fuel and still more allow the setting of both parameters.
Level measurement in steam boilers is a criticalmeasurement for plant operators in theprocess industry. Device failure, which results in a safety-oriented shutdownof thesteam boiler, is a verycostlyaffair. For this reason, Endress+Hauser recommends the 2oo3 architectureif instrument availability is a top priority. Please refer to the information
Measurement of CO 2 in Flue Gases 6515 Series DS/6515–EN Rev. C 2 Fuel Economy and CO 2 Measurements Cost of fuel is a major item in the budget of all concerned with the operation of industrial boiler plant. If combustion is inefficient, fuel is wasted and money spent needlessly. Many industrial concerns have proved that significant savings
Location: 2 West Market Street, Suite 500, West Chester, PA 19382, United States Effects of fuel preparation equipment on boiler performance. Fuel preparation equipment readies the fuel for combustion and can have a significant impact on emissions. The preparation equipment includes the crushers, pulverizers and drying systems on coal-fired units; fuel oil heaters and pumps on oil-fired units; refuse handling, mixing or drying equipment on refuse-fired boilers; or fuel
For sensitive systems such as power boiler oxygen measurement, technological advances offer the opportunity to more accurately control the combustion environment, leading to lower fuel usage and
Many boiler measurements can be challenging because of the physical design of the process, fuel variability and other issues, but proven technologies exist to deliver desired business results. An experienced combustion process control engineer can help plant owners and operators resolve root cause measurement issues.
2.0 Fuel Analysis Procedures and Methods The EPA boiler and process heater test program is requesting fuel variability data for fuel-based HAPs. The fuel analyses requested include: mercury, chlorine, fluorine, and metals (antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, manganese, nickel, phosphorus, and selenium) for any
