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.
Sep 06, 2001· As suggested in Table 1, the fuel cost savings from using a 10 bhp electric boiler, compared to keeping the 150 bhp main boiler in operation, amounts to at least $4.37 per hour in the case of the gas fired boiler. This means that the typical $20,000 installed cost of this electric boiler can be recovered in less than 4600 hours of operation.
The steam produced by an electrode type boiler depends on. the level of water in the basket. There are two general designs of electric boilers. They are the. low water cut-off. An immersion-type electric boiler has. elements. The load on an electrode-type electric boiler is maintained by the. amount of electrode covered by water.
An electrode boiler has a very quick response time. As it doesn't directly generate pollution, no pollution control system is needed. Unlike fossil fuel or conventional electric boilers, no boiler component is at high temperature except the water itself. As compared to other boilers, electrode boilers experience little thermal stress.

Electric Boilers Electric boilers are noted for being clean, quiet, easy to install, and compact. Because there are no combustion considerations, an electric boiler has minimal complexity (no fuels or fuel handling equipment) with easily replaceable heating elements. An electric boiler may be the perfect alternative to supply low or high pressure
Jan 17, 2015· If money is no object, Viessmann has launched its CHP boiler in the UK. The company says it will generate £1,000 in electricity and FITs each year, but it costs £22,000 to buy.
Small Standard Electric Steam Superheaters. ACME Electric Steam Superheaters are available for use with steam boilers as an auxiliary piece of equipment. Our superheaters are all custom made and built to meet the specific design requirements of each application.
Ajax Boiler is located in Santa Ana, California. Ajax Boiler is a designer and manufacturer of boilers and commercial grade water heating products. The company has extensive industrial experience and expertise in combustion and heat transfer, control and systems engineering, and pressure vessel design.
An advantage of an electric boiler is, that it a) has a high steaming rate b) can be operated at high pressures and temperatures c) produces very dry steam d) has a high efficiency of energy transfer from the electricity to the boiler water e) does not require an operator
When boilers are connected to a common header, it is required that an ample free blowing drain be provided between the stop valves if either or both boilers have ____. a. handholes b. manholes c. over 10 tubes or flues d. more than one safety valve
