water tube fire tube wood fired boilers 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.
Technical advantages 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.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace.
FireCAD software is being used by Steam Boiler manufacturers and Engineering consultants across the globe from over 30 countries. Design software for Grate Fired Boilers, Water Tube Package Boilers, Fire Tube Boilers both fired and waste heat type (Steam Boiler and Hot Water Boiler), Combi boilers, Economizers, Air heaters and Superheaters is available.
2017-9-18 · duction process. Steam or hot water is generated for lumber drying and process requirements. Wood burning boilers however, normally create considerable ash and soot build-up in the firetubes, resulting in inefficient heat transfer and a loss of steam pressure. Most wood-fired boilers require manual tube brushing. This means shutting down
Alibaba offers 8,122 wood fired tube boiler products. About 97% of these are boilers, 1% are other machinery & industry equipment. A wide variety of wood fired tube boiler options are available to you, such as natural circulation, once through.
2019-5-21 · The only railway use of water-tube boilers in any numbers was the Brotan boiler, invented in Austria in 1902 by Johann Brotan and found in rare examples throughout Europe. Hungary, though, was a keen user and had around 1,000 of them. Like the Baldwin, this combined a water-tube firebox with a fire-tube

Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or
2019-5-13 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
Our Water Tube Boilers can use any fuel type including wood, agricultural waste, gas and oil. Their output range can be a large capacity output or small capacity of steam, our recommendation for the fuel type and type of water tube boiler will depend on your application and use of the water tube boiler.
