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.
Nov 20, 2019· Cochran Boiler is a vertical drum axis, natural circulation, natural draft, low pressure, multi-tubular, solid fuel fired, fire tube boiler with internally fired furnace. It is the modified form of a simple vertical boiler. In this boiler, the fire tubes are placed horizontally. The efficiency of this boiler is much better than the simple
The Cochran boiler is vertical, multi-tube boiler generally used for small capacity steam generation. Cochran boilers are made in different sizes of evaporative capacities ranging starting from 150 to 3000 kg/hr. and working pressure up to 15 bar.
The Cochran boiler was produced by Cochran & Co. of Annan. It is a multi-tubular vertical fire tube boiler having a number of horizontal fire tubes. It is the modification of a simple vertical boiler where the heating surface has been increased by means of a number of fire tubes.
Oct 07, 2018· Simple vertical boiler and Cochran boilers are examples of vertical boilers. Horizontal boilers: In this type of boilers, the axis of the shell is horizontal. Lancashire Boiler, Locomotive Boiler, and Babcock and Wilcox Boilers are Horizontal Boilers.
A locomotive boiler is a device which is used to create steam from water by using heat energy. It is a horizontal drum axis, multi-tubular, natural circulation, artificial draft, forced circulation, mobile, medium pressure, solid fuel fired fire tube boiler that has an internal fire furnace.
All steam boiler designs are avail from 6 Bar up to 28 Bar. Steam Boiler, Model: ST37 . Cochran’s ST37 Package Steam Boiler is of horizontal three pass wet back design and constructed in accordance with BS EN 12953. This CE marked boiler is designed to meet the latest European environmental legislation and Medium Combustion Plant Directive
Cochran Boiler Definition: Cochran Boiler is one of the best types of vertical, multi-tubular boiler which has a number of horizontal fire tubes used for the generation of steam. Line Diagram of Cochran Boiler: The diagram of Cochran Boiler is shown below.
Jan 31, 2017· It is a Horizontal drum axis, natural draft, natural circulation, multitubular, stationary, high pressure, solid fuel fired, externally fired water tube boiler. It was discovered by George Herman Babcock and Stephen Wilcox in the year 1967.
A vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam -powered vehicles and other mobile machines, including early steam locomotives .
2). COCHRAN BOILER: 2). COCHRAN BOILER It is one of the best types of vertical multi-tubular boiler, and has a number of horizontal fir tubes. Cochran boiler consist of a cylindrical shell with a dome shaped top where the space is provided for steam.
