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.
Rheem's Prestige High Efficiency Liquid Propane Combi Boiler Rheem's Prestige High Efficiency Liquid Propane Combi Boiler provides an efficient, continuous supply of domestic hot water used for faucets, showers, washing machines, etc.) and provides hydronic space heating for residential applications such radiant floors, baseboards, hydronic air handlers, etc.
Jan 29, 2005· "When the bolier pressure reaches 1 bar, the boiler stops working, i.e. both the hot water and central heating are lost. At the moment, when the pressure drops off, I have to open a valve to re-increase the pressure. I have been told that the boiler operates at about 1.2bar, so I …
Pressure: 14, 12, 10, 8, 16 bar. The RL is a horizontal fire-tube with three passes reverse flame steam boiler. The combustion chamber is completely cooled by …
How often should I need to top up the pressure in the heating system? When the heating system is cool, the pressure should be between 1 and 1.5 bar on the pressure gauge (the indicator needle would usually be in the green section). If pressure is below 0.5 bar (down in the red section), water has been lost from the system and must be replaced.
All referenced page numbers are from the 2007 ASME Boiler & Pressure Vessel Code. Formula. To determine the maximum allowable working pressure of a boiler drum during different operating conditions you can use the formula contained within ASME Boiler & Pressure Vessel Code PG-27 Cylindrical Components Under Internal Pressure page 10.
A boiler in which water is heated for the purpose of supplying hot water at pressures of not more than 160 psi and temperatures not to exceed 250° F. Hot Water Supply Boiler A low pressure hot water heating boiler with a volume of more than 120 gallons, or a heat input of more than 200,000 BTU per hour, or an operating temperature of more than
2.1 Water-Tube Boilers ( Drum Type) - The feed water, boiler water and condensate, for water-tube boilers shall cotiply with the requirements given in Table 1. NOTE -In case of recovery boilers operating at low boiler pressures of I.5 to 2.0
Oct 02, 2015· This is normally between 1 and 2.5mb depending on model of boiler but normally around 1.5mb is the average. Manufacturers min working pressures are based on the meter only giving 19mb, the drop on the pipework being 1mb and the drop inside the case being 1-2.5mb. so a boiler with a 1.5mb drop inside the case will have a min working pressure of
Eric's graph indicates "gauge pressure". When you use the steam tables, you have to add "atmospheric pressure" (Patm) to "gauge pressure" (Pg) to get "absolute pressure" or P. Adding 1 bar at sea level is about right. 1 bar = 0.987 atmosphere = 29.53 inches of mercury
