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.
Fire tube boilers usually consist of a single furnace tube and a burner. Hence, the control systems meant for heating purpose inside these boilers is kept very simple. Due to their comparatively low operating pressures, the accessories needed to support fire tube boiler systems can be obtained at very economical rates.
Oct 31, 2016· How a Firetube Steam Boiler Works - Boiling Point Watch as Steven explains how the hot gases flow through the boiler and how firetube boilers turn heat into …
Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.
A complete line of Indeck Volcano “A” style package boilers are offered to provide the ability to fire the dirtier fuels while still incorporating the benefits offered with a package designed steam generator. The “A” type boiler is fully shop assembled, rail shippable up to steam capacities of 300,000 Ib/hr. If your project requires an industrial boiler, watertube steam packaged boiler
Apr 22, 2019· Water tube boilers can take up less physical space for large-capacity units. Water tube boilers can be 90% efficient, as compared to a 75% limit for fire tube designs. The design of water tube boilers is generally more complex than for fire tube boilers, and maintenance is typically greater.
Package Boiler. Packaged boiler is the most common and efficient type of fire tube boiler used in industry to produce steam and hot water. This boiler delivers to site as a whole package factory assembled. The package boiler only requires electricity, water, steam and fuel connections and it …
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
Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used by industrial facilities and power plants for process loads and can have an operating pressure of 16 to over 1,000 psig.
Definitions Points of Interest egg-ended boiler: an early form of tubular wagon boiler, with hemispherical ends to support higher pressures.; Elephant boiler: an early multi-cylindered wagon boiler, popular in France.; express boiler: another term for small-tube water-tube boilers, on account of their high ratio between heating surface area and water volume, and thus their rapid steam-raising.
Boilers typically come in either a fire-tube or water-tube heating design, and they are designed either to run on natural gas or a dual-fuel option. Fire-tube vs. Water-tube. Most conventional boilers use a fire-tube design, in which hot flue gas runs through a tube that is surrounded by the water in the tank.
