WNS series horizontal internal combustion boiler is classic 3-pass wetback oil/gas fired boiler. After fuel is atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, called 1st pass; the high temperature flue gasses are collected in reversal chamber and then enter 2nd pass, which is grooved tube bundle area through heat convection, air temperature gradually falls and flows to front smoke box and enter 3rd pass, which is done in the smooth tube bundle area, and then through back smoke box lead to chimney and exhausted to the atmosphere.

Technical Advantages

Digitized Manufacture

The key processes including material cutting, rolling, drilling are made by advanced CNC machining process to reduce the assembly stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine with tidy and beautiful look.

Easy Operation and Maintenance

Fully intelligent operation, with automatic adjustment and protection of burning, water level, temperature and steam pressure. The smoke box door uses the hinge structure for easy inspection, inventory and cleaning.

Long Service Life

The way to weld Smoke tube and tube sheet is to first expand to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boiler service life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint are test by radiographic inspection.
Fin tube uses ND steel or stainless-steel material to avoid corrosion in the low temperature.
Inspection stops are set up to guarantee the sequence of expanding and welding to avoid cracking of the tube sheet holes.

Less Fuel Consumption

High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ and reduce heat lost.
Sufficient steam storage room and heating area to generate high quality steam and high thermal power.
Condenser is added to recycle the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce flue gas emission temperature and increase the thermal efficiency over 98% and save operating cost.

Heat Recovery | Resources & Guides | Carbon Tru

Heat recovery is the collection and re-use of heat arising from any process that would otherwise be lost. The process might be inherent to a building, such as space heating, ventilation and so on, or could be something carried out as part of business activity, such as the use of ovens, furnaces and the like.

Proper Procedure for a Boiler-Room Assessment

2015-9-16 · Next, the assessor will observe how the boiler is set up to control totally dissolved solids in boiler water to maintain proper conductivity. If effluent is going down the drain, a blowdown heat-recovery system, which puts valuable energy into a boiler's feedwater stream, likely will be recommended.

A New System of Absorption Heat Pump Vs. Boiler fo

Using a heat pump system with a boiler, the temperature of flue gas of the boiler can be drooped to dew point and the waste heat in the flue gas and condensation heat can be recovered deeply. In this paper, a new type of system, absorption heat pump vs. boiler, is proposed in which the waste and vapor in flue gas can be recovered efficiently.

Continuous Blowdown Heat Recovery Systems, Hea

2015-6-3 · This plate and frame heat exchanger package requires a minimum amount of space in the Boiler Room. Extra plates can be added if blowdown and make-up rates increase. In many cases an approach of 2°F is possible making this a very efficient heat recovery package. Design Features. Maximum Heat Transfer from blowdown to boiler make-up water.

Total heat recovery of gas boiler by absorption hea

A new technology for condensing heat recovery from gas boiler is presented. • Absorption heat pump and direct-contact heat exchanger are combined in this system. • Field test shows that the temperature of the flue gas can be cooled below 30 °C. • This technology can improve the heat capacity of gas boiler

Analysis of two‐stage waste heat recovery based o

Waste heat recovery (WHR) is crucial to the efficiency improvement of natural gas‐fired boiler systems. Two‐stage WHR systems based on the natural gas‐fired boiler were analyzed from the viewpoints of thermal efficiency and heat transfer irreversibility.

10 Things to Know About Boilers | Boiler Exper

Some people prefer boilers because they can set their thermostat at a lower temperature and the radiant heat makes the room feel warmer than the actual air temperature. Others say boilers provide more balanced heat throughout the home during the winter months. 3. What are the most important things to know about your boiler heating system?

Heat Recovery Systems - Babcock Wans

What are Heat Recovery Systems Best Suited to? This list is extensive as, in theory, any industrial process that produces waste heat can benefit from a Heat Recovery System. Common sources of waste heat that can be readily recovered and re used include: High temperature exhaust gas streams from furnaces, kilns, ovens and dryers; Boiler flue gases
