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: 108KB This involves sampling the flow at multiple points and under varying flow rates using a single-point Pitot tube. Using this technique, the true nature of the flow profile can be determined, and a reliable air flow measurement (typically, accurate to about 2 percent with good repeatability) can be obtained where it is needed on the boiler.
Nov 05, 2015· However, although you may think that getting the boiler with the maximum flow rate will be the best option, you could actually be wasting your money & time if the mains water supply to your house is less than the boiler can handle – for example, you could buy a boiler with a flow rate of 12 litres per minute but your mains pressure only
Size Boiler Feed. Before you begin! If condensate return temperature is 200°F or above (at sea level) check available NPSH to avoid potential cavitation problems. Pump Flow Rate. Each pump on a boiler feed unit is sized based on the total load of boilers fed by specific pump feeds at one time.
the boiler is constructed for either low pressure steam or high pressure steam to 150 psi. 1. Gas Flow Heat transfer design of the Model WLF boiler provides four pass flow to ensure maximum heated gas travel and heat transfer. Refractory lined steel exhaust ports are incorporated for heated gas flow direction from the
if boiler is turned off – Domestic Hot Water Prioritization (DHWP) – Low Water Flow Indication – Outdoor Reset – Includes Sensor – Contacts on Any Failure – Inlet & Outlet Water Temperature Sensors – F or C Display – Boiler Set Point – Night Setback – Lead Lag up to 8 boilers
File Size: 2MB We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
Apr 12, 2020· boiler basics and types of boilers, water tube boiler and fire tube boiler. what is a boiler and its types, smoke tube boiler and water tube boiler. advantages and disadvantages of it. wet back design , dry back design.
File Size: 1MB the boiler has a burner with a 10:1 turndown ratio. When multiple boilers are used, care must be taken to assure proper proportional flow through each of the units. If flow is not properly balanced, wide variations in boiler firing rates can occur and, in extreme cases, the resulting outlet water temperatures may not be at the desired point.
