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.
6.7 star efficiency rating; Never run out of hot water; Delivers over $1000 of savings over the warranty of the heat exchanger* Smallest domestic condensing gas water heater
Continuous and Intermittent Blowdown Learning Outcome When you complete this module you will be able to: Describe the purposes, equipment and operation of continuous and intermittent the CBD line equal to 1% or more of the overall boiler steam flow rate. Heat Recovery The flow of CBD water from the boiler causes a slight decrease in overall
Author: Dean Heckscher The Madden Orifice Meter gives the boiler operator precise repeatable control of the continuous blowdown flow rate. 17 different hole sizes are drilled in the stainless steel orifice plate. Each hole is precision drilled to a diameter that will produce the flow. By selecting a larger hole the continuous blowdown flow is increased, or by selecting a smaller hole number on the index band the
capable of precise flow control of continuous boiler blowdown using the straight edge orifice principle at a boiler operating pressure of ___ p.s.i.g., with a blowdown flow range from ___ PPH to ___ PPH. 2. The flow control shall consist of: A multiple orifice meter with an attached filter and sediment
A continuous flow hot water system is usually a smaller, wall mounted unit that heats the water as you use it, rather than storing it like more traditional hot water systems will do. As the name suggests, the unit provides continuous water flow until the shower or the tap being used is turned off.

Optimal flow rate for condensing boiler I have a Vitodens 200 8-32 for a two storey brick 1914 house(of 2700 sqft including basement) heating a combination of about 350 sqft of cast iron radiation on a fat pipe gravity system converted to forced circulation as well as 400 sqft of cast iron radiation piped home-run.
The Madden Orifice Meter gives the boiler operator precise repeatable control of the continuous blowdown flow rate. This boiler blowdown valve utilizes 17 different hole sizes which are drilled in the stainless steel orifice plate. Each hole is precision drilled to a diameter that will produce the flow shown on the flow chart, see pages 3 and 4.
Continuous Flow Hot Water “Continuous flow” accurately describes how they work. You never run out of hot water because, unlike storage tank systems, it does not rely on pre-heating a quantity of water. You could have a house full of visitors, be last in the shower queue, and still have hot water.
The Continuous Circulation Concept In Hydronic Heating - By J.R. Fiedrich, originally published 1981-low temperature modulation, a standard feature of European hydronic heating system for many years, smoothes out the highs and lows of the heating curve caused by on-off circulation, saving fuel and offering a high level of heating comfort.
Sep 12, 2017· That's right, the Alde Flow doesn't require any gas, 230 V electric or dedicated 12 V (it plugs into the 3020 Compact HE boiler for its 12 V). It is a cleverly designed heat exchanger, that uses the heating fluid to pre-heat the water coming into the boiler.
