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.
In the prior art, heavy duty high pressure boilers necessitated the use of very heavy and bulky materials because of the high pressures generated in the boiler. In particular, the steam drum must have very thick walls to sustain the high pressures developed in modern boilers.
Nov 23, 2011· Boilers are one of the most commonly misunderstood pieces of home heating equipment. As a leading provider of boiler repair in Park City, we often get questions and concerns related to the safety of the machinery, especially in relation to high or low pressure issues.. The truth is that any residential boiler equipment is designed with family usage in mind.
Feb 02, 2016· HIGH PRESSURE BOILERS A boiler is called a high pressure boiler when it operates with a steam pressure above 80bar. The high-pressure boilers are widely used for power generation in thermal power plants. Example: Lamont boiler, Benson boiler, loeffler boiler, Babcock and Wilcox boiler Features of High pressure Boilers 1. Forced circulation of
Meaning of High Pressure Boilers: These are used to increase the efficiency of the plant. These are developed because of rising cost of fuel and restrictions on air pollution. Modern power generation plants generally use high pressure boilers. These high pressure boilers have pressures above 140 bar and the temperature may be up to 540 – 610°C.
Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to …
Oct 27, 2016· Thus, a boiler operation at high pressure will require less heat addition for steam generation. Features of High-pressure Boilers: High-pressure boilers have the following functions: Forced circulation of water – in all modern high-pressure boilers, the force circulation of water is maintained with the help of pumps. It increases the help of
In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination. Both mechanical factors such as boiler design, high water levels, load characteristics and chemical factors such as high solids concentration, excessive alkalinity, presence of contaminants contribute to the creation of carryover.
The water tube type boiler is used for high-pressure, high-temperature, high-capacity applications. The Main boiler design depends on its application, ie. for motor ships, a small fire tube boiler would be satisfactory. The features that are embodied in modern propulsion duty boilers are: Large furnaces
Pressure:0.7-2 Mpa; WNS gas-fired boilers are wetback fire-tube boilers with a two-pass or three-pass design. They use threaded flue tubes for heat transfer and install economizer and condenser on the tail, managing to achieve a thermal efficiency up to 98%.
Author: LEARN AND GROW modern high pressure high duty boiler Agents. 2019-9-6 · Boilers are machines that generate high-temperature, high-pressure steam on ships. They power the ship as it moves across the water and power other important machinery. Prior to 1973, boiler manufacturers instructed the Navy to coat boilers with external insulation containing about 15 .
