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.
Standard 189.1-2011, Standard for the Design of High-Performance Green Buildings Standard 189.1-2014, Standard for the Design of High-Performance Green Buildings With more than 57,000 members from over 132 nations, ASHRAE is a diverse organization dedicated to advancing the arts and sciences of heating, ventilation, air conditioning and
Apr 18, 2014· NBBPVI 264 Criteria for Registration of Boilers, Pressure Vessels, and Pressure Retaining Items presents a uniform criteria for a manufacturer’s registration of its certification that a given boiler has been manufactured to an acceptable standard. ASHRAE: This society provides many resources related to the design and performance assessment of
This standard applies to gas and oil-fired steam and hot water Packaged Boilers, as defined in Section 3, that have an Input Rating equal to or greater than 300,000 Btu/h, that are: 2.1.1 A steam boiler designed to operate at or below a steam pressure of 15 psig; or
complies with standard 90.1. Project Summary The Twin Rivers Elementary/Intermediate School will house 800 students of the Mckeesport Area School District. It is a two story building of 30,000 sq. ft. The Mechanical system is designed to save 30% of energy when compared to ASHRAE standard …
A poorly maintained steam boiler system will cost more to operate in the long run and could ultimately fail altogether. Why Do Steam Boilers Fail? In a steam boiler system, the two primary causes of failure are: 1. Departure from Nucleate Boiling (DNB) is caused by deposition (scaling) causing localized overheating of heat transfer surfaces.
File Size: 1MB ASHRAE: Major HVAC Systems & Equipment Below is a comprehensive list of all the major HVAC system types and related equipment The System Types include: Air Distribution Cooling Heat Rejection Cooling Pump Heating Heating Pump Control Miscellaneous Equipment Details:
the ASHRAE Standard 124, Liu, et al., 8. conducted laboratory evaluations of the performance of heating boilers combined with indirect tanks for DHW. The energy factor (EF) was found to range 0.45 to 0.50 and a linear relationship was found between the output capacity of the boiler and the EF with de-creasing EF with increasing size.
Standard Scope AHRI closely follows ASHRAE's Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings. Standard 90.1 provides minimum requirements for the design of energy efficient buildings. The first edition of ASHRAE Standard 90.1 was published in 1975 and revisions were approved in 1980, 1989, 1999.
OUTSIDE DISTRIBUTION SYSTEMS DESIGN MANUAL . Vol 1 ST EAM BOILERS 4 . 2.4 Life Cycle cost analysis . 2.4.1 The DOE requires that agencies must estimate the life -cycle costs and energy consumption of a building and compare it to the minimum criteria set forth in the applicable baseline ASHRAE or IECC standard.
